摘要
近年来,随着能源短缺以及生态环境问题不断加剧,考虑分布式新能源的多能源微电网作为一种新型供电模式,受到更多的关注。因此,科学、全面地评价考虑分布式新能源的多能源微电网的综合效益,可以为微电网的建设提供指导,具有较高的现实意义。提出了一种基于前景理论和VIKOR法的微电网效益评价方法。首先,根据微电网的发展特点和实际属性,构建了考虑经济性、能源利用效率和环境因素的微电网效益综合评价指标体系;考虑决策者的主观风险倾向,根据前景理论建立前景价值函数,采用改进AHP法和熵权法进行主客观综合赋权;然后采用VIKOR法对各种微电网方案进行分析与评价;最后,通过仿真验证了该方法具有较高的合理性和有效性,并且光伏微电网系统的年运行费用低,节能环保、综合效益相对较高。
In recent years,with the shortage of energy and the growing problem of ecological environment,multi-energy microgrid has received more attention as a new power supply mode.Therefore,the scientific and comprehensive evaluation of the comprehensive benefits of the multi-energy microgrid considering the access of distributed new energy can provide guidance for microgrid investment and has high practical significance.Under the above background,a micro-network benefit evaluation method based on prospect theory and VIKOR method was proposed.Firstly,according to the development characteristics and actual attributes of the microgrid,a comprehensive evaluation index system of microgrid benefit considering economics,energy utilization efficiency and environmental factors is constructed.Considering the subjective risk preference of decision makers,the prospect value function is established according to the prospect theory.The AHP method and the entropy weight method are used to carry out the subjective and objective comprehensive weighting;then the VIKOR method is used to analyze and evaluate various microgrid schemes.Finally,the simulation proves that the VIKOR evaluation method based on prospect theory has higher rationality and effectiveness.Moreover,the photovoltaic microgrid system has low annual operating cost,energy saving and environmental protection,and the comprehensive benefits are relatively high.
