摘　　要：To integrate different renewable energy resources effectively in a microgrid, a configuration optimization model of a multi-energy distributed generation（DG） system and its auxiliary equipment is proposed. The model mainly consists of two parts, the determination of initial configuration schemes according to user preference and the selection of the optimal scheme. The comprehensive evaluation index（CEI）, which is acquired through the analytic hierarchy process（AHP） weight calculation method, is adopted as the evaluation criterion to rank the initial schemes. The optimal scheme is obtained according to the ranking results. The proposed model takes the diversity of different equipment parameters and investment cost into consideration and can give relatively suitable and economical suggestions for system configuration.Additionally, unlike Homer Pro, the proposed model considers the complementation of different renewable energy resources, and thus the rationality of the multi-energy DG system is improved compared with the single evaluation criterion method which only considers the total cost.为了有效整合微电网中不同新能源发电设备,提出了一种面向多能互补分布式新能源发电系统及其辅助设备的电源配置优化模型.该模型首先确定电源配置的初始方案,然后根据用户偏好对初始方案进行优选.通过层次分析指标权重计算方法得到各初始方案的综合评估指标值,并对初始方案进行排序.针对不同型号设备参数多样性及投资成本的差异,该方法可以给出相对合适、经济的电源配置方案建议.此外,较之目前主流Homer Pro,所提出的规划方法考虑了多种新能源之间互补性,相比仅考虑综合成本的单一评价方式,提高了多能源微网配置的合理性.
