摘要
针对典型带海水淡化负荷的风光柴储互补独立微电网,提出了考虑全寿命周期净费用、可再生能源利用率以及污染物排放水平的多目标优化设计模型。在既定控制策略下,采用十进制最优保留遗传算法进行求解,获得微电网中分布式电源和储能系统的容量优化配置。对某独立海岛微电网进行优化设计,并与微电网优化软件HOMER计算结果进行比较,结果表明所提出的优化设计方法更加合理、可行。
Aimed at the island microgrid integrated with wind turbine,photovoltaic,diesel generator,energy storage,and desalination plant,a multi-objective optimal design model considering the allocation ratio of net present cost（NPC） in the full life cycle,the utilization of renewable energy and the pollutant emission level is proposed.The optimal number of distributed generators and the optimal capacity of energy storage are determined as optimization variables.Based on the established control strategy,a floating elitist preserved genetic algorithm is used to solve this problem.The island microgrid is designed and the simulation results are compared with the HOMER optimization results to illustrate that the proposed method is more reasonable and feasible than that of HOMER.
