摘　　要：针对单个微电网中存在严重的风、光利用率不足的问题,从需求侧响应入手,建立一种微电网群协调优化调度模型。模型通过能量管理中心协调微电网群供给侧的可再生能源,实现各微电网之间能源互补,并根据需求侧响应转移柔性负载和调度自身的发电机组,实现微电网的优化运行。以三个微电网构成的微电网群为例进行实验,验证需求侧响应与微电网之间的协调优化调度策略的可行性,并进行各策略之间的对比分析。实验结果表明,所提出模型能够有效降低储能装置的使用频率。Aiming at the serious problem of insufficient utilization of wind and light in a single microgrid,a coordinated optimal dispatching model of multi-microgrid is established from the demand side response.The model coordinates the renewable energy on the supply side of microgrids through the energy management center,realizes the energy complementation among microgrids,and transfers the flexible load and dispatches its own generator set according to the demand side response,thus realizing the optimal operation of microgrids.Taking a multi-microgrid composed of three microgrids as an example,the feasi-bility of coordinated optimal scheduling strategy between demand side response and microgrid is verified,and a comparative analysis of each strategy is given.The experiment results show that the proposed model may effectively reduce the use frequency of energy storage devices.
