  • The Australian Energy Market Operator (AEMO) is investigating technological and functional solutions to the challenge of integrating large amounts of distributed, residential-scale photovoltaic (PV) generation. Information is provided on the following five key elements necessary to perform management of PV feed-in: device hardware, communication protocols, network infrastructure, a management system, and interconnection agreements. EPRI conducted interviews with representatives from entities facing similar challenges, including from the United States, Germany, Japan, and parts of Australia outside of the National Electricity Market and South West Interconnected System. The interviews and research revealed similar efforts to AEMO, yet none in widespread use that simultaneously address all three challenges of 1) high PV penetrations, 2) consisting mostly of small, distributed PV systems, and 3) on systems without strong (or any) interconnections to neighboring countries or regions. In considering solutions, a holistic view of PV management that includes more than just feed-in management (e.g. other advanced inverter functionalities and customer control of their net energy output) is likely on the horizon.

  • This report shows how different countries deal with the DER data collection, with a focus on PV systems. This report also provides a complete overview of all the relevant aspects that need to be addressed and foresee information that will be relevant in the future. A growing trend towards centralised databases can be observed, in several countries, the owner of DER are obliged to register their systems in a central database and to keep this register up to date. However, the data model and thereby the level of detail in the individual registers varies a lot. Data of PV plants are necessary for a range of use cases. Policy makers should know the impact of policies on the market, FIT agencies must know exactly which system produces how much energy, and system operators must be able to calculate the impact of the PV system to their grid, to name just a few. In this report, the different use cases are addressed and recommendations for the implementation of a database are given.

  • This paper, prepared as a sectoral note for the Lifelines report on infrastructure resilience, investigates the vulnerability of the power system to natural hazards and climate change, and provides recommendations to increase its resilience. It first describes how power outages are often the consequence of natural disasters and outlines the main vulnerabilities of the power sector. It then proposes a range of approaches and solutions for building a more resilient power sector – from increased robustness to greater flexibility – showing that the additional cost of resilience is not high if resources are well spent. Finally, it describes how emergency preparedness and disaster recovery encompass not only technical aspects, like asset strengthening or criticality analysis, but also “softer” skills, like governance, regulatory or capacity building, and education.

  • This report was prepared to provide guidance for analyzing climate resilience challenges and opportunities in the power sector. The document is intended to be relevant to public and private sector stakeholders―particularly, the electricity sector―who are interested in evaluating how climate change hazards may impact the ability to provide service and implement measures to enhance resilience to climate change. The reference is limited to coastal climate hazards of flooding and permanent inundation due to SLR, as well as flooding from storm surge associated with extreme storm events. The document includes examples of climate resilience challenges and opportunities related to generation, transmission, and distribution assets, recognizing that the affected sectors may have different responsibilities for different types of assets or portions of the overall electricity system. This report provides principles that are meant to apply broadly to key aspects of any climate resilience analysis rather than instructions for a specific analysis. It also includes general reference on how to estimate the costs and benefits of resilience measures but does not serve as a manual for calculating economic benefits of resilience measures.

  • Climate hazards and extreme weather affect all components of the electric grid system, from generation to end use. Increasing temperatures, decreasing water availability, more intense storm events, and sea level rise affect the ability of the electric grid to produce and transmit electricity from fossil, nuclear, and existing and emerging renewable energy sources. Most electricity infrastructure is built for past or current climate conditions. Due to long lifetimes, electricity systems are likely to be exposed more frequently to more extreme climate conditions than those for which they were designed, and may not operate as intended under changing climate conditions. Utilities, regulators, state energy offices, and other electricity system planners are beginning to conduct environmental risk assessments, develop climate resilience plans, and incorporate changing climate conditions into long-term planning processes. Here, we highlight the analytical resources available for sensitivity assessment of electrical grid components under extreme weather and climate, and identify gaps in the literature on quantitative methods available for assessment of component vulnerability.

  • Cyber-secure, resilient energy is paramount to the prosperity of the United States. As the experience and sophistication of cyber adversaries grow, so too must the US power system’s defenses, situational awareness, and response and recovery strategies. Traditionally, power systems were operated with dedicated communication channels to large generators and utility owned assets but now there is greater reliance on photovoltaic (PV) systems to provide power generation. PV systems often communicate to utilities, aggregators, and other grid operators over the public internet so the power system attack surface has significantly expanded. At the same time, solar energy systems are equipped with a range of grid-support functions, that—if controlled or programmed improperly—present a risk of power system disturbances. This document is a five year roadmap intended to chart a path for improving cyber security for communication-enabled PV systems with clear roles and responsibilities for government, standards development organizations, PV vendors, and grid operators.

  • Recently developed Distributed Energy Resource (DER) interoperability standards include communication and cybersecurity requirements. In 2018, the US national interconnection standard, IEEE 1547, was revised to require DER to include a SunSpec Modbus, IEEE 2030.5 (Smart Energy Profile, SEP 2.0), or IEEE 1815 (DNP3) communication interface but does not include any normative overarching cybersecurity requirements. IEEE 2030.5 and associated implementation requirements for California, known as the California Smart Inverter Profile (CSIP), prescribe the greatest security features—including encryption, authentication, and key management requirements. SunSpec Modbus and IEEE 1815 security requirements are not as comprehensive, leading to implementation questions throughout the industry. In this paper, (a) the elements of IEEE 2030.5 encryption, authentication, and key management guidelines are analyzed, (b) potential scalability gaps are identified, and (c) alternative technologies are explored for possible inclusion in DER interoperability or cybersecurity standards.

  • In the present report, active power management, as a part of ASM is described and analysed from the perspective of a close collaboration of TSOs and DSOs, for congestion management in both distribution and transmission grids and system balancing when such services are provided in a market-based approach by flexibilities owned and operated by third parties. Many other ASM solutions coexist as mentioned in the toolbox above, but they are not analysed in the present report. In addition, reactive power management has been left out of the report. The reason to concentrate first on congestion management and balancing services provided by third parties is the importance of TSO–DSO coordination for these processes to ensure the security of supply. In a later stage, other elements or purposes of ASM could be commonly investigated by DSOs and TSOs.

  • Effective integration of large scale DER into the electric network as well as utilization of DER services for wholesale markets and distribution network services will require operational and market coordination between AEMO and distribution network operators. This involves developing effective system architecture, including market designs, and operational structures (including controls) to execute DER coordination reliably, otherwise customer value may be negatively impacted. This analysis raises the need for early identification and action of long-lead time matters and the potential need for interim measures to be implemented by AEMO under the current regulatory regime. To this end, this report developed by the Newport Consortium of leading experts on DER coordination architectures summarises international experiences to-date and employs comparative analysis to assist AEMO in exploring options for future system architectures for the coordination of DER.

71 2016 The Value of Aggregators in Electricity Systems Burger, Scott; Chaves-Ávila, Pablo; Battle, Carlos; Pérez-Arriaga,, Ignacio J Article Market-based and tariff-based solutions No file uploaded. https://energy.mit.edu/wp-content/uploads/2016/01/CEEPR_WP_2016-001.pdf
  • Aggregators are being lauded as critical in enabling DERs to provide valuable electricity services at scale; in this light, regulatory and policy bodies are discussing the role of aggregators and even the need to support their market entry. In order to shed light on this debate, this paper reflects on the economic fundamentals of aggregators. We perform a critical review of the potential value of aggregators, defining the factors that is determining and will determine their role in power systems under different technological and regulatory scenarios. We identify three categories of value that aggregators may create: fundamental, transitory, and opportunistic. Fundamental value (e.g. economies of scale) is intrinsic to aggregation and is independent of the market or regulatory context. Transitory value may be diminished by technological or regulatory advances; for example, “energy boxes” that automate market interaction could mitigate the value in aggregators doing so. Opportunistic value emerges as a result of regulatory or market design flaws and may endanger the economic efficiency of the power system.

  • AEMO is working with the industry to implement a Wholesale Demand Response (WDR) mechanism in the National Electricity Market (NEM). The WDR mechanism allows demand side (or consumer) participation in the wholesale electricity market at any time, however, most likely at times of high electricity prices and electricity supply scarcity. ‘Demand Response Service Providers’ (DRSP) classify and aggregate the demand response capability of large market loads for dispatch through the NEM’s standard bidding and scheduling processes. The DRSP receive payment for the dispatched response, measured in Mega-Watt hours (MWh) against a baseline estimate, at the electricity spot price.

  • Due to an ever-increasing rise in proliferation of distributed energy resources (DERs), the paradigm of passive electrical distribution networks is shifting toward active distribution systems. This new environment introduces a plethora of challenges that cannot be managed by traditional tools, whose utilization could compromise the reliability and efficient operation of distribution feeders. This article systematically reviews state of the art in different DERs management software solutions available today. Additionally, it establishes distinguished roles and responsibilities of different levels of hierarchy in distinct solutions that are all commonly called DERs management systems—DERMS (e.g., fully centralized versus fully decentralized DER management solutions). Lastly, it offers a viewpoint on the directions that hold potential for the power system community and industry to explore for further developments of more robust and intelligent DERMS, to successfully enable efficient transition into a new era of clean and sustainable power systems, encompassing active and dynamically changing distribution circuits.

  • Due to the large number of distribution transformers in the distribution grid, the status of distribution transformers plays an important role in ensuring the safe and reliable operation of the these grids. To evaluate the distribution transformer health, many assessment techniques have been studied and developed. These tools will support the transformer operators in predicting the status of the distribution transformer and responding effectively. This paper will review the literature in the area, analyze the latest techniques as well as highlight the advantages and disadvantages of current methodologies.

  • DERs can create new power system opportunities, but at the same time, can pose new challenges when a grid has not been properly prepared. Many jurisdictions are just beginning to understand how DERs fit into the wider energy landscape – what they are and what impacts they have on the grid, and how they can be used to improve system reliability and reduce overall energy costs. Meanwhile, other regions have built up experience with DERs, demonstrating that they can provide valuable services to the grid when incentivised with appropriate technologies, policies and regulations. Nonetheless, not all countries use the same electricity market model or are at the same stage of DER penetration, and the fit-for-purpose solutions will vary from place to place. This report reviews lessons from forerunners and distils best practices (with examples and case studies) to help policymakers, regulators and system operators across the globe understand what experience is most relevant to their own situation. Readers will be able to draw on a wide range of practical insights for electricity market design and regulation to help unlock the multiple grid benefits of DER technologies.

  • AEMO has been collaborating with the Clean Energy Regulator (CER) and the Clean Energy Council (CEC) to incorporate inverter settings checks into the CER’s existing inspection program as part of its Small-scale Renewable Energy Scheme. It was identified that as much as 40% of grid-connected inverters installed with rooftop solar PV systems since 2016 may not comply with some of the mandatory settings prescribed in AS/NZS 4777.2:2015 and the relevant Distribution Network Service Provider (DNSP) connection agreements. This is causing issues for grid reliability and security that without rectification will limit consumers’ choice to invest in DER. The information collected through the inverter settings checks in the CER inspection program will provide insights to better understand reasons for non-compliance to AS/NZS4777.2 and assist in improving processes to minimise this.

84 2020 Too much of a good thing? Global trends in the curtailment of solar PV O'Shaughnessy, Eric; Cruce, Jesse R.; Xu, Kaifeng Article Active management of distribution grid No file uploaded. Solar Energy https://www.sciencedirect.com/science/article/pii/S0038092X20309166?via=ihub
  • Solar photovoltaic (PV) systems generate electricity with no marginal costs or emissions. As a result, PV output is almost always prioritized over other fuel sources and delivered to the electric grid. However, PV curtailment is increasing as PV composes greater shares of grid capacity. In this paper, we present a novel synthesis of curtailment in four key countries: Chile, China, Germany, and the United States. We find that about 6.5 million MWh of PV output was curtailed in these countries in 2018. We find that: Policy and grid planning practices influence where, when, and how much PV is curtailed; Some PV curtailment is attributable to limited transmission capacity connecting remote solar resources to load centers; PV curtailment peaks in the spring and fall, when PV output is relatively high but electricity demand is relatively low. We discuss available measures to reduce PV curtailment as well as increasing PV curtailment in the contexts of evolving grids and energy technologies.

  • "Project RAIN — Resource Aggregation and Integration Network — is one of the first globally to explore how distributed generation and energy storage might be combined with flexible loads (such as electric vehicle chargers or smart thermostats) to respond optimally to dynamic system needs. Open standards and protocols such as SunSpec Modbus and OpenADR are being utilized in an effort to improve future system performance and reduce integration costs. Several controller vendors (both established and new entrants) were engaged in laboratory testing, though the field trial features a single control system that is coordinating DER from multiple suppliers. In this first report, findings are shared from the experimental design, laboratory testing, and initial field installation stages of the project."

  • "...This paper disseminates experiences from Urja Upatyaka, where an interconnected mini grid connecting six MHMGs was developed as a pilot project in western Nepal; as well as insights from a number of other such interconnected grids at different stages of development in Nepal. Development costs for the pilot project proved relatively high, and such projects will therefore only be commercially viable if the project cost can be reduced, or if significant increases in electricity consumption and hence revenue result from the development of the interconnected mini grid. Nevertheless, assessment of the pilot project, as well as feasibility studies from the other projects reveal that these have already delivered many direct benefits, as well as providing lessons which will facilitate further development of interconnected mini grids. This paper identifies some of the key benefits of Micro Hydro Interconnected Mini Grids2 (MHIMGs), and factors that can contribute to their successful deployment and operation."
