Optimal Configuration Of Microgrid Base On Hybird Gray Wolf Optimizer And Genetic Algorithm

With the development of technology,the shortagement of energy and environmental problems have attracted wide attention from all over the world.As an important way to solve this problem,the technique of renewable energy generation has developed rapidly.Distributed generation technology is a kind of renewable energy generation,which is great significance to solve environmental problems,improve the utilization of energy and solve the problem of power supply.Microgrid is an important way of distributed power generation integrations into Power System,and it has unique advantages in solving the power supply reliability problem in remote areas and improving the new energy access ratio of power grid.Ownning to the randomicity of wind and solar energy,it is improtant to find a reasonal plan to reach the goal of saving the investment of microgrid,improving energy efficieny and raliablility of power supply in optimization problem of microgrid configuration.In this paper,I first analyzed the current research status of the technique of microgrid in the world,and discusses the future research trend,analysed and built the power models of photovoltaic cells,wind turbines,diesel generators and batteries.Then introduce the standard genetic algorithm,and add adaptive,parallel and natural disaster operators to improve it.And introduce the gray wolf algorithm and use it to improve the effectiveness of local search ability of genetic algorithm,the tests on standard test functions indicate that the hybird gray wolf and genetic algorithm has high search efficiency and accuracy.Then established the microgrid climate model,and the control strategy of the independent micro grid and the grid connected micro grid is analyzed.The objective function base on new energy penetration and comprehensive investment cost is established,and the relative constraint conditions are determined,use HGW-GA to calculate the optimization configuration of microgrid.Considering the new microgrid's optimization configuration in the microgrid net base on energy complementation,and analyze the related factors.
