Optimal Allocation of Distributed Energy Storage Capacity in Power Grid With High Proportion of New Energy
Abstract
In order to reduce the waste of power resources caused by unreasonable capacity allocation, an optimal allocation method of distributed energy storage capacity in power grid with high proportion of new energy is proposed. Taking wind and solar power generation as the research object, the wind power generation model is established by using Weibull algorithm, the photovoltaic power generation model is established by using beta algorithm, and the energy storage system model is constructed based on the state of energy storage device. The economic benefits of power grid are taken as the objective function to constrain the grid side, DG and energy storage. On this basis, the model parameters are optimized by using particle swarm optimization algorithm, Finally, the optimal configuration of distributed energy storage capacity is realized. The experimental results show that the proposed method can quickly calculate the optimal energy storage configuration under the condition of constant power shortage rate, and the reduced economic loss increases significantly with the increase of power shortage rate. It has a certain research value.
