Research On Distribution Network Voltage Optimization With Distributed Generation

In recent years,with the deterioration of the environment,the global environmental protection and energy conservation issues of concern gradually increased.At the same time,along with wind power generation,photovoltaic power generation and so on through the renewable energy power generation technology matures,distributed power(Distributed Generation,DG)technology has become a hot research at home and abroad.DG has many traditional power generation methods do not have the advantages,such as flexible installation,power supply and harmless to the environment.However,after DG access to the distribution network,the distribution network will produce some changes we do not want to produce,such as distribution network structure changes,the distribution network may change in the control mode.Therefore,it is of great theoretical and practical significance to study DG access distribution network.The main contents of this article are.First introduce some of the typical distributed power technology and access to the grid.Secondly,the methods used in this paper are screened by summarizing the commonly used power flow calculation method.Then we introduce the particle swarm algorithm,the harmony search algorithm and the hybrid algorithm proposed in this paper,and analyze the superiority of the verification algorithm.Finally,the objective function of the voltage function and the network loss is established,and the simulation shows that the reasonable access mode can support the distribution network voltage.
