摘　　要：随着“双碳”目标下新型电力系统的发展,微电网规模日益增加,基于柔性互联的微电网群可实现微电网间互联互济,提高供电可靠性和经济性。针对柔性互联微电网群的优化调度问题,提出基于加速-鲁棒性目标级联法的微网群分层协同调度策略。首先,分别制定峰、平、谷不同时刻调度策略,建立微网群双层模型,上层是以微网群运营为主体的经济调度模型,下层是以子微网为主体的经济调度模型。其次,将智能软开关(soft open point,SOP)连在子微网末端的公共点,通过SOP实现子微网之间的互联,将微网与主网之间的交换功率作为耦合变量,采用加速-鲁棒性目标级联法实现上、下层模型的优化求解。最后,由算例分析表明:基于加速-鲁棒性目标级联法的优化调度方案能减少系统运行成本,实现整个微网群系统的协同优化调度。With the development of new power systems under the goal of“Dual Carbon”,the scale of microgrids is increasing.Multi-microgrids based on flexible interconnection can realize interconnection and mutual benefit among microgrids,and improve the reliability and economy of power supply.For the optimization scheduling of flexible interconnected multimicrogrids,a hierarchical collaborative scheduling strategy based on the accelerated and robust analytical target cascading is proposed.Firstly,scheduling strategies for peak,flat,and valley periods are formulated respectively,and a two-layer model of multi-microgrids is established.The upper layer is an economic scheduling model with multi-microgrids operation as the main body,and the lower layer is an economic scheduling model with sub-microgrids as the main body.Second,SOP is connected to the common point at the end of the sub-microgrid,and the interconnection between the microgrid is realized through SOP,and taking the exchange power between the microgrid and the main network as the coupling variable,the optimal solution of the upper and lower models is realized by accelerated and robust analytical target cascading.Finally,an example analysis shows that the optimized scheduling scheme based on accelerated and robust analytical target cascading can reduce the operating cost of the system and realize the cooperative optimal scheduling of the whole multi-microgrids system.
