摘　　要：微网技术作为分布式微源和负荷的接入和管理平台,其经济调度方法已成为一门重要课题。随着直流负荷和微源的应用越来越广泛,交直流混合微网开始受到关注。针对传统微网优化运行模型对交直流混合微网并不适用的问题,并且为了提高交直流混合微网运行应对实时情况的能力,提出了基于储能电量控制的交直流混合微网实时经济调度方法。该方法首先制定策略来计划储能充放电功率,其次基于此建立了实时经济调度模型的目标函数和约束条件。算例表明,所提出的方法能够适用于交直流混合微网实时经济调度,具有正确性和有效性。As an access and management platform for distributed micro sources and loads, microgrid economic dispatch technology has become an important issue. With the increasing application of DC load and micro source, AC/DC hybrid microgrid is becoming more and more popular. In the light of the problem that the traditional microgrid optimal operation model is not suitable for AC/DC hybrid microgrid, the real time economic dispatch method of AC/DC hybrid microgrid based on energy storage control is put forward to meet the real-time situation. Firstly, the method is used to plan the energy storage and discharge power. Secondly, the objective function and constraint conditions of the real-time economic dispatch model are established. The numerical examples show the correctness and effectiveness of the proposed method.
