基于合作博弈的智慧能源社区协同运行策略

Cooperative game-based coordinated operation strategy of smart energy community

智慧能源是我国能源侧改革的重心之一,而智慧能源社区是整合大规模产消者的用户级智慧能源系统。在此背景下,提出了一种基于合作博弈的智慧能源社区协同运行策略,能够有效激励智慧能源社区内个体参与者与社区整体协同运行。在计及可再生能源出力不确定性的基础上,建立了智慧能源社区合作博弈模型,并设计了适用于大量参与者的合作博弈模型收益分配方案,显著提高了模型的计算效率和可扩展性。对智慧能源社区算例进行仿真分析,结果验证了所提模型可有效提高社区总收益,基于核仁的收益分配方案有效可行,在实现经济效益最大化的同时促进了可再生能源的就地消纳。

Smart energy is one of the focal points of China’s energy side reform,and SEC(Smart Energy Community)is a user-level smart energy system integrating large-scale proconsumers.In this context,a cooperative game-based coordinated operation strategy of SEC is proposed,which can effectively motivate the individual participants to cooperate with the whole community.Considering the uncertainty of renewable energy output,the cooperative game model of SEC is established,and the income allocation scheme of cooperative game model applicable to a large number of participants is designed,which significantly improves the computational efficiency and scalability of the model.The simulative and analysis results of SEC examples show that,the proposed model can effectively improve the total SEC income,and the nucleolus-based income allocation scheme is effective and feasible,which not only maximizes the economic benefit,but also promotes the local consumption of renewable energy.
