该文围绕包含柴油发电机、风力发电、光伏发电和铅酸蓄电池的独立微网系统中的容量配置问题,提出了包含微网全寿命周期内的总成本现值、负荷容量缺失率和污染物排放的多目标优化设计模型。该优化模型在控制策略上,考虑了多台柴油发电机的组合开机方式、储能电池与柴油发电机之间协调控制策略,以及系统备用容量等问题。在优化变量上,选取设备类型和装机容量同时进行设计。最后利用自主开发的微网优化设计工具,针对某独立海岛微网系统开展了不同目标组合、不同控制策略下的分布式发电单元和储能电池的优化配置方案研究。
This paper presented a multi-objective optimal planning design model including net cost, loss of capacity and pollutant emission in life cycle for stand-alone microgrid system with diesel generators, wind turbine generators, photovoltaic generation and lead-acid battery. In this model, the two coordinated operating strategies between diesel generators and battery, dispatch method for multi diesel generators, and the reserve capacity had been considered. The type and capacity of distributed generation units had been selected as the optimal variables. Optimal allocation of distributed generation units and battery for an island microgrid system had been carried out under different combination objectives and different control strategies by the planning design system for mircogrid (PDMG).
