弱中心化分布式能源网络的多主体随机博弈与运行优化研究

随着信息物联、人工智能等技术发展和能源互联网建设，分布式能源的互动和运行逐渐向着扁平化方向发展。相对于完全去中心化来说，弱中心化分布式能源网络能够兼顾电网运营企业在能源网络中的重要作用和分布式能源P2P交易的需求，是未来分布式能源参与系统运行、互动和交易的发展方向，将推动系统架构、分布式能源运行策略、网络运行机制等发生巨大的本质变化。本项目针对弱中心化分布式能源网络带来本质变化和科学问题，从弱中心化分布式能源网络的随机博弈机理和纳什均衡出发，驱动随机博弈中的分布式能源个体决策与进化，设计引导网络运行趋向理论纳什均衡的最优机制，推演博弈和网络形态变化，最终建立实现分布式能源、用户、电网企业多方共赢的弱中心化分布式能源网络理论体系，推动分布式能源大规模接入下的新形态和新机制构建及发展，激发分布式能源建设动力和利用潜力，并指导与推动电网企业向服务化、共享化、平台型发展转型。

With the development of technology like the Internet of things(IOT), artificial intelligent (AI) as well as the construction of energy internet, the interaction and the operation of distributed energy resources (DER) gradually become more and more flatten. The weakly centralized DER network which takes into account the important role of power grid corporation in energy network and at the same time satisfies the P2P trading requirement for DER, will become the development trend for DER to participate in the operation, interaction and market trading of the system in the future and will bring essential changes to the system structure, operating strategy and mechanism of DER network. This project focus on the eventual changes and scientific problems that are brought by the weakly centralized DER network. Starting from the analyze of the stochastic dynamic game of the weak centralized DER network and the optimal solution of the Nash equilibrium, driving the individual DER in the stochastic dynamic game to decide and evolve, guiding the network running towards the optimal Nash equilibrium strategy, projecting the structure variation of the game and the network, and finally a theoretical system of multilateral win-win weakly centralized DER network involving DERs , users and power grid enterprises is able to be established. This will promote the construction and evolution of novel forms and mechanisms with large-scale connection of DERs, simulate the motivation of DER construction and its potential utilization, meanwhile, guide and encourage the power grid corporation to transform towards service-oriented and sharing platforms.
