考虑负荷需求响应的配电网三相不平衡优化
Three-phase unbalance optimization of distribution network considering load demand response
摘要
Abstract
The increasing penetration of new energy generation,controllable loads,and energy storage in the distribution network has posed challenges to the safe and stable operation of power grids,making it more difficult to analyze power flow optimization and the three-phase imbalance issue.The concepts of load demand response and phase-switchable loads were introduced to construct a node load demand response model considering phase switching.By utilizing the characteristics of shiftable,interruptible,and phase-switchable loads,the power distribution among phase nodes was improved.At the same time,a node energy storage operation model was constructed to further improve the operation indexes of the three-phase distribution network.In the Matlab environment,the model solving variables were defined,the convergence accuracy and other parameters were set,the CPLEX solver was invoked to solve the optimal power flow model of the three-phase distribution network,and different scenarios were set for comparative analysis.The data analysis showed that the multi-factor flexible adjustment could effectively reduce the three-phase imbalance indexes of the distribution network in the IEEE 33 example system.关键词
