Abstract

In recent years, the aggregation business has gained a lot of attention in Japan. Aggregators will make contracts with customers with photovoltaic (PV) power systems and battery energy storage systems (BESSs) including electric vehicles (EVs) to participate in electricity markets. Aggregators might have to pay electricity supply-demand imbalance charges when generated and consumed energies contracted at the day-ahead supply-demand market are different from those at the current day operation due to distribution network constraints such as voltage and power flow limitations. Therefore, the information on network constraints is very important for aggregators to determine their day-ahead schedules. In this paper, we evaluated the relationship between aggregator supply-demand schedules and the distribution system operation. It was assumed that the reverse power flow limitations due to network constraints are notified to the aggregators by distribution system operator (DSO). Two cases of the aggregators’ schedules of PV systems and stationary BESSs were compared in the simulations. In addition, aggregator strategies for making adequate schedules were evaluated.

考虑配电系统运营商通知信息的聚合光伏电池系统调度方法

近年来，聚合业务在日本受到了很多关注。聚合商将与光伏（PV）电力系统和电池储能系统（BESS）的客户签订合同，包括电动汽车（EV），以参与电力市场。由于配电网的限制，如电压和潮流限制，当日前供需市场上合同的发电量和消耗量与当天运行时不同时，聚合商可能需要支付电力供需失衡费用。因此，关于网络约束的信息对于聚合器确定其日前计划非常重要。在本文中，我们评估了聚合器供需计划与分销系统运营之间的关系。假设配电系统运营商（DSO）向聚合器通知由于网络约束而引起的反向潮流限制。在模拟中比较了光伏系统和固定BESS的聚合器时间表的两种情况。此外，还评估了制定适当时间表的聚合器策略。
