Voltage coordinated control of distribution network with high proportion distribution photovoltaic considering network partition
摘要
Abstract
Due to the high proportion of distributed photovoltaic access to the distribution network,the traditional centralized control is difficult to adapt to the voltage control problem in high-dimensional environment.Therefore,this paper proposes a voltage coordinated control of photovoltaic distribution network with high proportion distribution considering network partition.Firstly,the distribution network is divided into centralized topology and local topology according to the partition function algorithm.Secondly,aiming at the centralized topology,the voltage centralized control model of distribution network based on second order cone programming(SOCP)is established with the minimum sum of voltage deviation and network loss as the objective function.Aiming at the local topology,the minimum node voltage deviation is taken as the objective function,and the voltage fine control model with Markov decision process is established.Then,the CPLEX solver and the deep deterministic gradient algorithm are used to solve the regional model effectively.Finally,the method is applied to an actual 35 kV/10 kV distribution network.The simulation results show that the proposed method has a good control effect,which ensures the safe operation of the distribution network and improves the photovoltaic penetration rate.关键词
