摘要
综合能源园区是以新能源为主体的新型电力系统的基本单元,通过建设分布式电源,可以实现能源生产、消费就近完成和园区自我平衡。通过挖掘用户需求响应潜力,制定差异化丰枯电价,能够缓解分布式电源出力和用户电量的季节性不匹配矛盾,对此提出一种面向综合能源园区的丰枯电价定价方法。首先,根据用户的电量特征和需求响应特征,基于k-means聚类算法进行用户分类;然后,根据园区不平衡电量,基于k-means聚类算法划分丰枯时段;最后,构建优化模型,制定不同类别用户的丰枯电价。根据案例分析可知,基于该方法制定丰枯电价,能够有效促进分布式电源就地消纳,提高园区清洁能源消费比重和整体经济性。
Integrated energy park is the basic unit of new electric power system dominated by renewable energy.Depending on distributed generators,the energy production and consumption nearby and self-balance of park are achieved.The contradiction of seasonal load mismatch between distributed generators and users can be released by tapping demand response potential and stipulating different season of use(SOU)price.A pricing method for SOU price in integrated energy park was put forward accordingly.First of all,considering characteristics of load and demand response,users were classified by k-means clustering algorithm.Then,according to unbalance load of park,SOU periods were determined by k-means clustering algorithm.At last,the optimization model was established to stipulate SOU price of different types of users.As the case shown,based on this method,SOU price can promote local consumption of distributed generators efficiently and raise the utilization ratio of clean energy and overall economic benefit of park.
