摘要
如何兼顾经济性和环保性是分布式电源优化配置研究的主要目的。采用Nash均衡理论构建了以环保性和经济性指标为参与者的非零和博弈数学问题,建立了计算模型;采用遗传算法对计算模型的Nash均衡点进行了求解,并应用IEEE33节点配电系统进行了算例分析。结果表明在IEEE33系统优化配置中经济成本略增加1.2%的同时环境指标减少了5.2%,说明采用Nash均衡理论所建立的模型可以兼顾经济性和环保性的要求,得到了合理的分布式电源配置参数。
The way to balance economic benefits and environmental benefits is the main purpose of the study on the opti-mal allocation of distributed generations. First,with the environmental and economic indicators as participants,a math-ematical problem of non-zero-sum game is formulated using Nash equilibrium theory,and the corresponding calculationmodel is built. Second,genetic algorithm is used to work out the Nash equilibrium point of the calculation model,andan IEEE 33-node distribution system is adopted as a case study. The results show that in the optimal allocation of theIEEE 32-node system,the economic cost slightly increases by 1.2%,while the environmental indicator decreases by5.2%,indicating that Nash equilibrium theory can balance the economic and environmental protection requirements,and obtain reasonable parameters for the distribution of distributed generations.
