计及低碳效益的分布式发电优化配置

首先对电力系统各个环节进行低碳分析,针对配电网分布式发电DG(distributed generation)优化配置问题,提出了低碳费用、电压安全、有功网损这三个评估配电网效益的重要指标,在此基础上建立分布式发电多目标优化配置模型,应用最大满意度法将多目标规划转化成单目标规划问题,并用模拟植物生长算法PG-SA(plant growth simulation algorithm)对上述模型进行求解。算例表明该模型确定的分布式电源在配电网的位置和容量可有效减少碳排放、提高系统运行电压,降低有功网损。

Optimal Allocation of Distributed Generation Considering Low-Carbon Effect

The low carbon analysis of all aspects of power system was made.According to the optimal allocation of distributed generation(DG) in distribution network,three important indexes of low-carbon expense,voltage security and active power loss were introduced to evaluate distributed generation profits,and on this basis,the model of DG multi-objective optimization was established.The multi-objective program was turned into a single objective program by the maximum satisfaction method.An artificial intelligent algorithm named plant growth simulation algorithm(PGSA) was used to solve the optimal planning problem of DG.The example shows that the location and capacity of DG determined by proposed model in distribution network can effectively decrease the carton emission,improve the system voltage and reduce the active power loss.
