摘要

In order to reasonably design the battery and solar panel array of solar power supply system,a multi-objective optimization design method considering the array economy and supply reliability was proposed.Based on the battery charge and discharge characteristics and the solar panel power generation characteristics,combined with the load demand and the cost of batteries and solar panels,with the battery temperature correction factor,discharging depth,charging efficiency,solar radiation level and ramp correction factor,considered the two longest continuous rainy days and the shortest interval days,the arrays total price to evaluate the arrays economy and the potential failure probability to evaluate the arrays power supply reliability were proposed;the arrays comprehensive coefficient to evaluate array economy and power supply reliability was further proposed;the optimum design scheme of the battery and solar panel was determined.%为合理设计太阳能供电系统的蓄电池和太阳电池板阵列,提出一种综合考虑阵列经济性及供电可靠性的多目标优化设计方法.基于蓄电池充放电特性和太阳电池板发电特性,结合负载供电需求和蓄电池及太阳电池板成本,利用蓄电池温度修正系数、放电深度、充电效率和太阳能日辐射量及斜面修正系数,综合考虑两次最长连续阴雨天数及其最短间隔天数等,提出了评价阵列经济性的阵列总价和评价阵列供电可靠性的潜在故障概率,并进一步提出了综合评价阵列经济性和供电可靠性的阵列综合系数,从而确定经济可靠综合性能最优的蓄电池和太阳电池板阵列设计方案.
