摘　　要：为实现风/光/柴多能互补发电系统的经济运行,应用启发式算法以分布式发电投资、运行费用、向输电系统直接购电费用以及考虑环境因素费用总和最小为优化目标,分别对并网型和离网型两种情况进行规划和运行的综合分析,从而确定各DG类型的最优投入容量。研究结果表明:该模型可以全面评估分布式发电的经济性能,并对不同运行方式给出相应的最优配置方案,从而极大地提高系统的供电可靠性和经济可行性。This paper presents model to realize optimization of the wind/solar/diesel hybrid power generation system. While meeting the basic requirements of power systems, the minimum cost of the objective function is calculated considering investment and operating costs of distributed generation as well as environmental factors by means of Heuristic Algorithm.Comprehensive analysis of planning and running for on/off grid are used to identify the optimum capacity. Simulation results show that the model can be used to comprehensively assess the economical performance of distributed generation and the corresponding optimal configuration under different operation situations, thus greatly improve the reliability and economic feasibility of power systems.
