考虑综合承载力的主动配电网优化调度与运行

随着风、光渗透率不断提高，其多重时序波动与不确定性给主动配电网优化调度工作带来了挑战。为提高主动配电网应对不确定性扰动的能力，提出一种考虑综合承载力的主动配电网优化调度方法。首先，从主动配电网资源充裕度和运行安全性两方面提出了综合承载力指标体系。然后，计及多种主动管理资源的协调调度，构建了考虑综合承载力的主动配电网优化调度模型。其次，引入图论“破圈法”对网架编码策略进行改进，并采用混合编码粒子群算法对模型进行求解。最后，基于改进IEEE 33系统设计算例验证了所建模型的科学性和有效性。

Optimal Scheduling and Operating of Active Distribution Network Considering Comprehensive Carrying Capacity

With the increasing penetration of wind and solar power,the uncertainties bring great challenges to the optimal scheduling of active distribution netw ork.In order to improve the ability of active distribution netw ork to deal w ith uncertain disturbances,an optimal scheduling method is proposed to enhance the comprehensive carrying capacity of active distribution netw ork.Firstly,comprehensive carrying capacity is proposed from the aspects of resource adequacy and operation safety of active distribution netw ork.Then,based on the coordinated scheduling of various active management resources,an optimal scheduling model of active distribution netw ork considering comprehensive carrying capacity is constructed.Secondly,the graph theory"broken circle"method is introduced to improve the encoding strategy of the grid,and the hybrid encoding particle sw arm optimization algorithm is used to solve the model.Finally,an improved IEEE 33-node system is taken as an example to verify the validity of the model.
