决定分布式电源(distributedgenerator,DG)发挥最大效益的关键是在进行分布式发电系统规划时能够对众多DG类型进行合理的选择和配置。为此首先建立了各种DG的出力模型,然后以满足负荷增长需求、考虑环境效益的供电公司年总规划成本现值最小为优化目标,利用Homer软件对含有多种DG(包括风力发电、光伏发电、采用微型燃气轮机的冷热电联供)的分布式发电系统进行了仿真分析,并对风速、天然气价格以及排污处罚标准3变量进行了敏感性分析,最后得到分布式发电系统的优化配置结果。分析结果对城市大型DG项目规划和个人DG安装决策具有参考意义。

The key element to determine whether distribution generator (DG) can achieve better results or not is to reasonably select and configure various types of DGs during the planning process of distributed generation system. For this purpose, firstly the output models of various DGs are built; then taking meeting the demand of load growth and minimizing the present value of annual total programmed cost of power supply company in which the environmental effects are considered as optimization objectives, the simulation analysis on distributed generation system containing various DGs such as wind power generation, photovoltaic power generation and combined cooling, heating, and power (CCHP) by micro-gas turbine is performed, and the sensitivity analysis on three variables, namely the wind speed, the price of natural gas and the punishment criteria, is conducted; finally, the optimal selection and configuration results for distributed generation system is achieved. The obtained results are available for reference to the planning for large-scale urban DG projects and the decision-making of installing individual DG system.
