Capacity Optimal Research of Hybrid Energy Storage Systems for Stand-alone Wind/PV Micro-grid
Abstract
In order to reduce the cost of the energy storage system in stand-alone Wind/PV power generation system and improve the reliability of power supply, it is necessary to configure the capacity of energy storage system reasonably. An optimization model is constructed, which considers the total cost of the energy storage system in view of the energy storage life within the engineering use fixed number of year as the objective function, the dividing frequency of different types of energy storage’s own compensation frequency band as optimization variables, and considers the LPSP, SPSP, SOC as the constraint, then use the improved PSO algorithm to solve the optimization problem. Finally, the example indicated that the optimization model and algorithm are correct and effective.
