摘　　要：针对用电负荷时空聚集与新能源出力尖峰导致的配电网双向阻塞问题,鉴于市场环境下温控型负荷的响应潜力和移动式储能技术的时空灵活性,提出一种综合考虑市场机制与移动式储能的有源配电网日前–日内2阶段阻塞管理方法。首先,构建考虑温控型负荷响应特性的电力市场分层架构与交易机制,通过调整温控型负荷用电功率来实现配电网阻塞的日前管理;然后,考虑负荷响应不确定性及日前新能源发电功率预测误差,引入可适应配电网阻塞情况时空变化的移动式储能,搭建基于市场机制与移动式储能的日前–日内阻塞管理框架,在确保系统阻塞得以消除的同时兼顾经济性。算例结果表明所提方法可有效解决有源配电网阻塞问题,降低配电系统运营商阻塞管理成本。In allusion to the two-way congestion problem of the distribution network caused by the temporal and spatial accumulation of electricity load and the peak of renewable energy output,in view of the response potential of thermostatically controlled loads under the market environment and the spatiotemporal flexibility of mobile energy storage system technology,a day-ahead and intra-day two-stage congestion management method for active distribution networks,taking into account market mechanism and mobile energy storage,was proposed.Firstly,the hierarchical structure and trading mechanism of the power market considering thermostatically controlled load response characteristics were constructed,so as to realize day-ahead management of distribution network congestion by adjusting the power consumption of thermostatically controlled load.Secondly,considering the uncertainty of load response and the prediction error of day-ahead renewable energy output,the mobile energy storage system which could adapt to the spatiotemporal change of distribution network congestion was introduced to build a day-ahead and intra-day congestion management framework based on market mechanism and mobile energy storage,ensuring that system congestion was eliminated,taking into account economy simultaneously.The simulation results show that the proposed method can effectively solve the congestion problem of active distribution networks and reduce the congestion management cost of distribution system operators.
