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.

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.

Article	Active management of distribution grid			No file uploaded.			https://wires.onlinelibrary.wiley.com/doi/full/10.1002/wene.460	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.

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.

66	2019	An integrated approach to active system management with the focus on TSO–DSO coordination in congestion management and balancing	CEDEC, E.DSO, Eurelectric, GEODE, ENTSO-E	Study Report	Information exchange			No file uploaded.			https://www.entsoe.eu/news/2019/04/16/a-toolbox-for-tsos-and-dsos-to-make-use-of-new-system-and-grid-services/	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. Congestion Management

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.
