摘　　要：通过计算不同分布式电源配置方案的年发电费用、用户停电损失、环保成本,建立了综合经济性、可靠性、环保性评估的分布式电源优化配置模型。基于电力不足概率对分布式电源配置方案进行可靠性评估,给出不同可靠性目标下的最优配置方案,并对用户不同停电成本对配置方案的影响进行了敏感性分析。同时,将分布式电源对环境的影响也纳入了优化评估中,考虑了SO2和NOx等各种污染气体的排放特性,以及不同地区环保成本差异对优化配置结果的影响。算例分析表明,该模型能够全面评估各种分布式电源的性能,并针对不同用户的可靠性和环保要求提出了最优配置方案。A mathematical model for deploying distributed generation is proposed to consider overall economic performance, reliability and environment assessment at the same time, by calculating annual generation costs, the consumer＇s economic toss of power outage and environment protection costs. Loss of load probability is used to evaluate the reliability of power supply. Different optimal deployment scheme for distributed generators are given under different reliability targets. The sensitivity of different consumer＇s outage loss is also analysed. Meanwhile, environment influence of distributed generators is considered in the optimization evaluation process. Research on SO2, NOx emission characteristic of different kinds of distributed generators is given and deployment results under different environment protection costs are analyzed. Simulation results indicate that this model can evaluate the performance of distributed generators comprehensively and establish optimal deployment scheme which can satisfy consumers＇ different demands for reliability and environment protection.
