Island Isolated Microgrid Grid Design with Distributed Power Supply

分布式电源具有波动、随机和不可控特点,孤立海岛微电网中电源及负荷种类多样,给网架设计提出了更多的限制。为此,提出包含分布式电源的微电网网架设计方法。从光伏系统模型、风速概率模型、风力发电机模型和负荷概率模型出发,将分布式电源的概率数学模型应用到海岛孤立微电网规划中。将分布式电源的出力特性进行量化并合理优化配置,有效提高电网的运行效率,降低运行费用,减轻电能损耗,实现其经济性,有效提升孤立微电网的供电可靠性。

The distributed power supply has the characteristics of fluctuation,randomness and uncontrollability.The isolated island microgrid has various power sources and loads,which imposes more restrictions on the design of the grid.To this end,a microgrid grid design method including distributed power supply is proposed.Based on the photovoltaic system model,wind speed probability model,wind turbine model and load probability model,the probabilistic mathematical model of distributed power supply is applied to the island isolated microgrid planning.The output characteristics of the distributed power supply are quantified and the configuration is rationally optimized,the operating efficiency of the power grid is effectively improved,the operating cost is reduced,the power loss is reduced,the economy is realized,and the power supply reliability of the isolated microgrid is effectively improved.
