近年来，拥有太阳能光伏和电池的住宅消费者（又称产消者）数量一直在增加。现在存在激励措施，鼓励产消者以比自用模式更有利可图的方式使用电池。然而，这可能会增加产消者的出口或进口，从而导致电力流动，从而导致配电网络中的电压和热限制违规。这项工作为配电网络运营商 (DNO) 提出了一个框架，通过对产消者使用动态操作限制来确保 MV-LV 网络的完整性。各个产消者定期将其本地控制确定的预期操作（净出口/进口）发送给 DNO，然后 DNO 使用智能电表数据和潮流引擎评估网络完整性。如果检测到潜在的违规行为，则根据包含网络约束和公平性方面的三相最佳潮流来确定其最大运行限制。研究了一个真实的澳大利亚中压馈线，具有真实建模的低压网络和 4,500 多个家庭，其中产消者的本地控制根据能源价格进行操作。时间序列结果表明，所提出的框架可以帮助 DNO 确保产消者之间的网络完整性和公平性。此外，与澳大利亚采用的 5kW 固定出口限制相比，它为产消者带来了更大的利润。
The number of residential consumers with solar PV and batteries, aka prosumers, has been increasing in recent years. Incentives now exist for prosumers to operate their batteries in more profitable ways than self-consumption mode. However, this can increase prosumer exports or imports, resulting in power flows that can lead to voltage and thermal limit violations in distribution networks. This work proposes a framework for Distribution Network Operators (DNOs) to ensure the integrity of MV-LV networks by using dynamic operating limits for prosumers. Periodically, individual prosumers send their intended operation (net exports/imports) as determined by their local control to the DNO who then assesses network integrity using smart meter data and a power flow engine. If a potential violation is detected, their maximum operating limits are determined based on a three-phase optimal power flow that incorporates network constraints and fairness aspects. A real Australian MV feeder with realistically modelled LV networks and 4,500+ households is studied, where prosumers’ local controls operate based on energy prices. Time-series results demonstrate that the proposed framework can help DNOs ensure network integrity and fairness across prosumers. Furthermore, it unlocks larger profitability for prosumers compared with the use the 5kW fixed export limit adopted in Australia.
