摘要: 为促进微网间的能量互济和协调控制以及平抑微网与配网之间的功率波动,文章提出了可交易能源(transactive energy,TE)框架下的微网群动态电能交易策略。首先,设计了基于可交易能源平台的微网群电能交易结构,保证了市场参与者的隐私安全,提高了电能交易的灵活性;其次,构建了微网群动态电能交易模型,以计及储能电池退化成本和可控负荷调度补偿成本的微网成本最低为目标优化电能报价,以微网群电能交易成本最低为目标优化电能交易量,通过多轮竞价以协调微网间的电能交易,促进系统供需平衡,减小微网与配网之间的交互功率;最后通过3个互联的微网分析验证所提策略的有效性和经济性。

Abstract: In order to promote electricity transaction and coordinated control among microgrids and to smooth power fluctuation between the microgrid and the distribution network, a dynamic electricity trading strategy for multi-microgrid under transactive energy(TE) framework is proposed.Firstly, the electricity transaction pattern of multi-microgrid based on transactive energy platform is designed to ensure the privacy and security of market participants and improve the flexibility of electricity transaction.Secondly, a dynamic electricity trading model for multi-microgrid is established.The first objective is to optimize electricity price by minimizing the cost of the microgrid taking into account the cost of energy storage battery degradation and controllable load dispatch compensation.The second objective is to optimize electricity transaction by minimizing the total electricity trading cost of multi-microgrid.Then, coordinating electricity transaction among microgrids based on multi-round auction aims to promote supply-demand balance and reduce the power interaction between the microgrid and the distribution network.Finally,the effectiveness and economics of the proposed strategy are verified by three interconnected microgrids.

Key words: multi-microgrid, direct electricity transaction, transactive energy(TE), multi-round auction, coordination optimization
