摘要 为缓解乌鲁木齐地区环境污染状况,系统地研究了该地区独立风-光-蓄混合发电系统,提出了基于直流总线的独立风-光-蓄混合发电系统结构,对混合系统中的风力发电机、光伏模块及铅酸蓄电池等关键部件进行建模,经济模型采用总净现值成本和平准化能源成本模型,可靠性模型采用负荷失电率.依据乌鲁木齐地区风能、太阳能和户用负载数据,利用遗传算法对该地区独立风-光-蓄混合发电系统进行优化设计.结果表明:独立风-光-蓄混合发电作为一种新型发电方式,可以减少环境空气中总悬浮颗粒物、二氧化硫和氮氧化物等污染物的排放.优化的混合发电系统包括1台风力发电机、12.561 1 m2的光伏模块和14.701 9 kW·h的铅酸蓄电池,负荷失电率为0.019 8,系统最小总成本为87 262元.

Abstract: In order to alleviate environmental pollution in Urumqi, a stand-alone hybrid wind/PV/ba-ttery power system was systematically studied for this region; as a result, a DC bus-based new system was proposed. The wind turbines, PV modules and lead-acid batteries in the system were modeled respectively, and the two principal economic models include the total net present cost(NPC)and the levelized cost of energy(LCE). At the same time, the reliability of the system was expressed in terms of loss of power supply probability(LPSP). The hybrid system design was optimized by means of genetic algorithm(GA)with a series of data of wind speed, solar radiation and user load in that region. As a result, the proposed stand-alone hybrid wind/PV/battery power system can be served as a new type of power generation in Urumqi to reduce the emissions of total suspended particulate(TSP), sulfur dioxide(SO2)and nitrogen oxides(NOx)etc. The optimal hybrid system consists of one wind turbine with 1 kW capacity, 12.561 1 m2 PV module and batteries with 14.701 9 kW·h capacity. The system has a loss of power supply probability of 0.019 8 and the minimum total cost of 87 262 Yuan. 
