Optimization of Distribution Terminal Selection Considering Load and DG Random Timing Characteristics

随着配电设备一二次融合的进行,配电终端二次规划简单可行。基于此,提出一种计及负荷与DG随机时序特性的配电终端选型优化方法,对DG出力以及各类负荷停电损失进行建模,并综合考虑投资成本、运维成本以及停电损失构建配电终端选型优化模型。最后,通过算例验证了方法的可行性。配电网三相不平衡对运行安全性和经济性影响很大。

With the primary and secondary integration of distribution equipment,the secondary planning of distribution terminal is simple and feasible.Based on this,a distribution terminal selection optimization method considering the stochastic time sequence characteristics of load and DG was proposed.The DG output and various load outage losses were modeled,and the optimization model of distribution terminal selection was constructed considering the investment cost,operation and maintenance cost and outage loss.The feasibility of the method was verified by an example.The three-phase unbalance of distribution network has a great impact on operation safety and economy.
