基于储能惯量支撑的高比例新能源基地效益提升优化方法
A Method for Optimizing the Allocation of Comprehensive Benefits of a High Proportion of New Energy Bases Based on Energy Storage Inertia
摘要
Abstract
With the continuous improvement of the penetration rate of new energy and the access of a large number of power electronic equipment,the power system gradually shows a trend of decreasing inertia and weakening system strength,which makes it difficult for equipment such as grid-based fans to maintain grid-connected status in some cases.The energy storage system has the ability to establish and support voltage,which can effectively solve the problem that new energy is difficult to integrate into the weak power grid.In this paper,the inertia response characteristics of each part of the wind-solar-storage in the high-proportion new energy base are analyzed,and on this basis,the inertia of the new energy station is modeled,and the minimum inertia demand of the new energy base is formed.From the perspective of cost and benefit,an optimal configuration model of energy storage for the comprehensive benefit improvement of the grid-connected system with a high proportion of new energy bases,considering the constraints of frequency safety and stability,is established.The particle swarm optimization configuration model is used to solve the energy storage optimal configuration model,and the kmeans clustering method is used to construct the typical seasonal scenarios on a daily basis.Finally,a typical scenario system analysis is carried out to verify the effectiveness of the proposed configuration method.关键词
