摘　　要：提出了一种含多种分布式电源的三相不平衡微网综合优化调度策略。首先,确定了三相不平衡微网安全、经济、高效运行的评价指标;建立了多目标优化调度模型,并通过对多目标调度模型的求解得到微网的运行策略。其次,对各目标函数从不同的运行角度进行了分析,以充分利用多目标方法的有效性。算例仿真验证了所提出的优化调度策略在充分发挥各种分布式电源作用方面的优势。This paper proposes a comprehensive optimization scheduling strategy for unbalanced microgrid with three- phase imbalance including multiple distributed generations. Firstly, we determine the evaluation indices for the security, economy and efficient operation of three-phase unbalanced microgrid; establish the multi-objective optimization scheduling model; and obtain the running strategy of microgrid through solving the model. Secondly, we analyze each objective function from different operation angles, which can make full use of the effectiveness of the multi-objective approach. The example simulation verifies the effectiveness of the proposed optimization scheduling strategy in giving full play to all kinds of distributed generations.
