Research on optimal allocation of energy storage in distribution network based on improved gray wolf algorithm
In order to achieve the goal of carbon peak and carbon neutrality,it is necessary to greatly improve the absorption capacity of renewable energy,but the randomness of renewable energy such as photovoltaic and wind energy is strong,which increases the difficulty coefficient of stable operation of the power system,so reasonable allocation of energy storage in the distribution network is one of the ways to ensure its sustainable development.Based on this,this paper analyzes the network loss improvement cost and the life cycle cost of energy storage to form a complete comprehensive cost model,and uses the voltage offset index to construct a sound optimal configuration model of energy storage in distribution network.At the same time,the improved gray wolf algorithm is used to calculate and improve its actual space exploration ability and rationality of the configuration scheme.Finally,after IEEE33 node distribution network simulation simulation,the model and the improved gray wolf algorithm can reasonably control the network loss,increase the stability of the grid voltage,and have great advantages in calculation speed.
