Coordinated Optimization of Distribution Network Based on Linear Model of Four-Quadrant Energy Storage Power
摘要
Abstract
High permeability of photovoltaic in distribution network may cause problems such as net load curve deformation,voltage deviation and network loss increase.A coordinated optimization strategy of active and reactive power of distribution network considering linear modeling of four-quadrant energy storage power regulation is proposed.Firstly,the active and reactive power regulation capability and operation characteristics of various regulatory resources in the active distribution network are analyzed,especially the operation boundary of photovoltaic and energy storage power.Based on this,a linear modeling method of four-quadrant energy storage power regulation is proposed.Then,considering the power capacity constraints and energy capacity constraints of the energy storage,the objective function and constraint conditions of the distribution network coordinated optimization model are established,which can be solved through the second-order cone algorithm.Finally,the improved IEEE 33-bus system is used to verify the effectiveness and feasibility of the proposed method.关键词
