多能源微网参与电-气多能源市场的多主体主从博弈交易策略

Multi-agent Stackelberg game trading strategy of electricity-gas multi-energy market considering participation of multi-energy microgrids

针对多能源微网(MEMGs)具有丰富可调节资源的特点,基于区域电-气综合能源系统中配-微网络间不同层级的能源交互特性,提出一种MEMGs参与多能源市场的交易框架和多主体主从博弈的交易模型。通过MEMGs策略性参与区域能源市场交易,降低各主体购能成本,实现多个能源市场下多主体互动交易。将配电系统运营商和配气系统运营商视为领导者、各个多能源微网运营商(MEMGO)视为跟随者,以配电网节点边际电价和配气网节点边际气价作为各MEMGO的能源结算价格,构建考虑MEMGs参与电-气多能源市场的多主体主从博弈交易模型;在证明该模型存在Stackelberg均衡解的基础上,通过交替方向乘子法求解所提模型以保证各主体的信息私密性;通过REGES E13-G7和REGES E123-G20测试系统验证了所提多主体交易策略的可行性和有效性。

In view of the characteristic of multi-energy microgrids(MEMGs)with abundant adjustable resour-ces,and based on the characteristic of energy interaction between distribution network and microgrid at dif⁃ferent levels in the regional electricity-gas integrated energy system,a trading framework and a multi-agent Stackelberg game trading model considering the participation of MEMGs in the multi-energy market are proposed.Through the strategic participation of MEMGs in regional energy market transaction,the energy purchase cost of entities is reduced,and the multi-agent interactive trading in multi-energy market can be realized.The distribution system operator and gas system operator are regarded as the leaders,and the multi-energy microgrid operators(MEMGOs)are regarded as the followers,taking the distribution locational marginal electricity price and distribution locational marginal gas price as the energy settlement price of each MEMGO,the multi-agent Stackelberg game trading model considering the participation of MEMGs in the electricity-gas multi-energy market is established.Based on proving the existence of Stackelberg equilib⁃rium solution in the model,the proposed model is solved by the alternating direction method of multipliers to ensure the information privacy of each entity.The REGES E13-G7 and REGES E123-G20 test systems are used to verify the feasibility and effectiveness of the proposed multi-agent trading strategy.
