【摘要】 针对独立型水-光-柴-储微电网,综合考虑经济性、环境效益和供电可靠性,提出了微电网的电源容量多目标优化配置模型,即采用粒子群优化算法在一定的控制策略下对所提出的电源容量多目标优化配置模型进行求解,得到微网系统中储能装置和各分布式电源的容量。以我国西藏某地区为算例对微电网进行电源容量优化设计,通过对模型求解结果与柴油发电机单一供电计算结果及单目标容量优化结果的对比分析,验证了所提模型的合理性和优越性。更多还原

【Abstract】 A multi-objective optimal configuration model of distributed generator capacity has been proposed for the isolated microgrid with hydropower,solar power,diesel power and battery.The model takes economical,environmental benefit and power supply reliability into consideration simultaneously.Under the established control strategy of microgrid,particle swarm optimization algorithm was used to solve the model in order to obtain the capacity of distributed generators and energy storage devices in the microgrid.The microgrid of Tibet area was taken an example.The multi-objective optimization of the example were compared with the results that use diesel generators only and the results solved by single target capacity optimization model.The analysis results verify the rationality and superiority of the proposed multiobjective model.更多还原
