| 摘要: |
| 针对风／光／储独立供电微网，提出一种基于可靠性的最优容量配置方法。首先，考虑风速和光照强度的随机性，分别建立风力发电机、光伏阵列以及蓄电池的数学模型；在此基础上建立包含设备投资费用、运行维护费用、蓄电池重置费用以及系统可靠性和能量过剩率指标的优化配置模型，并确定约束条件；其次，采用改进粒子群优化算法对微网容量优化问题进行求解。在MATLAB环境下编程实现微源最优配置方案，结果表明优化后的微网不仅保证了系统供电可靠性，而且节省了经济成本。 |

| Abstract: |
| A capacity configuration optimization method based on reliability is proposed for standalone wind／photovoltaic／storage microgrid. The models of wind generator，photovoltaic array and storage battery are built with the consideration of random wind speed and light intensity，based on which，a configuration optimization model containing equipment investment，operation／maintenance cost，storage battery replacement，system reliability index and energy excess rate index is established，and the constraints are determined. The improved particle swarm optimization algorithm is adopted to solve it. The optimal configuration scheme of microsources is programmed in MATLAB and results show that，with the power supply reliability ensured，the optimized microgrid is more economic. |
