摘　　要：为探索离网型光储柴混合发电系统中光储容量配置与月最低光照有效时间和年平均光照有效时间的关系,基于Homer Pro微电网软件对光储柴混合发电系统进行模拟,在用电特性相同的情况下,分析了中国某地、苏里南某地和秘鲁某地3个光照强度不同地区理论计算的光储容量配置和Homer Pro微电网软件衍生优化的净现值最低光储容量配置的关系。结果表明:3个不同光照强度地区采用月最低光照有效时间理论计算的储能容量与Homer Pro微电网软件衍生优化的储能容量比值为1.134、1.052和1.019,光伏容量比值为0.97、1.34和1.30;采用年均光照有效时间理论计算的储能容量与Homer Pro微电网软件衍生优化的储能容量比值为1.134、1.052和1.019,光伏容量比值为1.46、1.48和1.50;采用年均光照时间理论计算的光储容量配置与Homer Pro微电网软件衍生优化的光储容量配置比值较为稳定,所以采用月平均光照时间理论计算的储能容量乘以1.07、光伏容量乘以1.48可以得到趋近于Homer Pro微电网软件衍生优化的净现值最低的光储容量,这对于研究离网型光储柴混合发电系统的光储容量配置具有重要参考意义。To explore the relationship between the configuration of PV-BESS capacity and the effective utilization hours of monthly minimum effective hours of day light in the off-grid PV-Diesel-BESS hybrid power system,Homer Pro microgrid software was used to simulate the off-grid PV-Diesel-BESS hybrid power system,In the case of the same power consumption characteristics,the relationship between the theoretically calculated PV-BESS capacity configuration and the lowest net present value(NPV)PV-BESS capacity configuration optimized by Homer Pro microgrid software derivation is analyzed for three different solar resource regions,one in China,one in Suriname and one in Peru.The results show that the ratio of BESS capacity calculated by the monthly minimum effective hours of day light average to the BESS capacity optimized by Homer Pro microgrid software is 1.134,1.052 and 1.019,and the ratio of PV system capacity is 0.97,1.34 and 1.30 in three different solar resource regions.The ratio of BESS capacity calculated by the average annual effective hours of day light to the BESS capacity optimized by Homer Pro microgrid software is 1.134,1.052 and 1.019,and the ratio of PV system capacity is 1.46,1.48 and 1.50.The analysis shows that the ratio between the PV-BESS capacity configuration calculated by the monthly minimum effective hours of day light average and the PV-BESS capacity configuration derived from Homer Pro microgrid software is relatively stable. Therefore, the BESS capacity calculated by the average annual effective hours of day light multiplied by 1.07 and the PV system capacity multiplied by 1.48 can obtain the PV-BESS capacity with the lowest NPV, which is close to the Homer Pro microgrid software derived optimization, which is an important reference significance for the study of the PV-BESS capacity configuration of the PV-Diesel-BESS hybrid power system.
