本文讨论了规划和运营具有高度分布式能源（DER）渗透率的电力系统所固有的技术，监管和政策挑战：发电机，灵活的需求和配电网内连接的储能。全球许多自由化的电力系统都看到了DER的增长，包括分布式可再生能源发电的巨大容量。本文从最优配电网络的前提下，满足最低成本的电力系统的目标，同时满足客户的期望的可靠性和社会的可持续发展的愿望。它强调了决策者在市场和监管安排方面面临的主要挑战，这些安排支持从大量小型、可变和往往不确定的资源中提供能源和灵活性。这些挑战包括需要尊重该系统的技术限制并确保其可操作性，发展设计良好的机制以支持创新，以及在市场行为者之间适当分担风险。本文的一个主要贡献是讨论了更积极的配电系统运营作为资本投资的替代品所提供的机会及其监管和政策影响。最后，本文提出了政策的优先事项，以促进高度分布式的电力系统。
This paper discusses the technical, regulatory and policy challenges inherent in planning and operating power systems with high penetrations of Distributed Energy Resources (DER): generators, flexible demand and energy storage connected within electricity distribution networks. Many liberalised electricity systems worldwide are seeing growth in DER including significant capacities of distributed renewable generation. The paper starts from the premise that optimal distribution networks are those that satisfy the objective of a lowest cost power system whilst meeting customers' expectations of reliability and societal desire for sustainability. It highlights major challenges that policy makers face in respect of market and regulatory arrangements that support energy and flexibility provision from a large number of small, variable and often uncertain resources. These challenges include the need to respect the technical limits of the system and ensure its operability, development of well designed mechanisms to support innovation, and an appropriate share of risk between market actors. A key contribution of the paper is to discuss the opportunities offered by more active distribution system operation as a substitute for capital investment and its regulatory and policy implications. Finally, the paper presents priorities for policy to facilitate a highly distributed electricity system.
