Research on optimal configuration of hybrid energy storage capacity for wind-solar generation system
摘要
Abstract
The energy storage system can effectively solve problem of intermittence, volatility and source-load misalignment of distributed renewable energy, especially wind-solar generation in the micro-grid system. Different energy storage forms have their own characteristics in terms of response time, power and energy capacity, technological maturity and cost, etc. The hybridization of two or more types of energy storage technology will be a good solution to meet the technical and economic requirements of energy utilization system. In this paper, a hybrid energy storage system consisting of compressed air energy storage, lithium battery and supercapacitor is proposed, and mathematical modellings of three energy storage systems are established. For different characteristics, a power allocation method based on secondary moving average filtering and a capacity optimal allocation method based on continuous operation are proposed. Based on a practical customer load requirement, the power and capacity configuration results of the hybrid energy storage system are obtained, and the operational characteristics are analyzed. The research indicates that in the system of distributed renewable energy micro-grid, the coupling of multiple energy storage technologies can not onlyfully utilize the advantages of each type of energy storage, but also compensate for their respective disadvantages through mutual cooperation. That has an important role and significance of fully utilize renewable energy and satisfy demand of electric load, and has a good engineering application prospect in the field of distributed energy utilization.关键词
