计及蓄电池寿命的风光储微网系统能量优化管理
摘要：随着新能源电力比重的快速增长,风光储互补发电已成为我国电力供应的重要组成部分。本文提出一种针对风光储微网系统的能量优化管理策略。综合考虑系统运行成本、蓄电池寿命损耗成本和购电环境成本,建立经济调度模型;以综合发电成本最低为目标,考虑出力约束和安全性能约束,利用粒子群优化算法对该模型求解,产生能量管理策略的调度参数,实现功率优化调度。在不同天气条件下,对本文策略和常规策略进行了算例对比,验证了优化效果。基于算例数据,进一步讨论了蓄电池充放电深度和次数对寿命的影响,并证明在本文策略中蓄电池的使用寿命较长。
Abstract:With the rapid growth of the proportion of new energy power, wind-photovoltaic (PV)-storage complementary power generation has become an important part of China's power provision. An energy management strategy for the wind-PV-storage microgrid system is presented in this paper. Considering the system operation cost, battery life loss cost and environment cost of purchasing power, an economic dispatch model is built. Taking the minimum comprehensive cost of power generation as the objective, considering the constraints of power output and safety performance, the particle swarm optimization (PSO) algorithm is used to generate the parameters of the energy management strategy for optimizing power scheduling. Under different weather conditions, the better optimization effectiveness of the proposed strategy is verified by comparing its simulation results with that of the conventional strategy. Based on the case data, the influence of the depth and frequency of battery charge and discharge on the battery's life is discussed, and the battery life is longer under the proposed strategy.
