摘要
目前关于微网电源容量配置的研究主要针对独立运行情况,虽配置结果可保证系统运行的可靠性,但增加了冗余投资。针对并网运行的风/光/储微电网,制定了其运行策略,分别建立了微网经济性和供电可靠性模型,采用多目标模拟退火粒子群优化算法求取模型的最优解集,得到了微网中风力和光伏发电及储能系统容量配置方案。结果表明,相比于独立运行,在相同的可靠性要求下,以并网运行的角度配置风/光/储微电源容量关系,可明显降低微网投资成本。
Currently,research on micro-sources capacity configuration is concentrated on the case of isolated microgrid. Though configuration results can guarantee the reliability of the system connected or disconnected,the redundant investment is increased. In this paper,the operation strategy for the parallel operation of wind / photovoltaic /storage microgrid is developed,and the economy model and power supply reliability model are established respectively,using multi-objective simulated annealing particle swarm optimization algorithm to calculate optimal solution set of the model. The configuration scheme of the wind power,photovoltaic power and energy storage system is obtained. It shows that as compared with the isolated operation,to configure the micro-sources capacity relationship of wind / photovoltaic / storage microgrid in view of parallel operation,the investment cost will be decreased obviously under the same reliability requirement.
