能量与备用市场主体自调度的电热综合能源系统优化

为更好地管理电热综合能源系统中能源交易以提高系统运行的经济效益,同时考虑新能源入网带来系统运行的不确定性,本文提出能量与备用市场主体自调度的电热综合能源系统两阶段优化方法.第一阶段基于博弈模型分析主从(双层)交易的市场主体之间多种能源的交互方式,以系统经济性运行为优化目标来求解市场主体之间的均衡交互策略.第二阶段是鲁棒...

Optimization of Integrated Electric and Heating Energy System with Self-dispatching by Energy and Reserve Market Players

To better manage the energy transactions in an integrated electric and heating energy system to improve the economic efficiency of system operation while taking into account the uncertainties in system operation brought by the integration of new energy sources,a two-stage optimization method for the integrated electric and heating energy system with self-dispatching by energy and reserve market players is proposed in this paper.At the first stage,based on the game model,the interaction of multiple energy resources between the market players of the Stackelberg(two-tier)game is analyzed,and the equilibrium interaction strategy for the market players is solved with the optimization goal of the system’s economic operation.At the second stage,a robust feasibility test is conducted,where the modified column and constraint generation algorithm is used to solve the robust feasible solutions at the first stage.The result of an example shows that the proposed model can realize the system’s economic operation through energy management by market players,and the reliable operation of the system under the uncertain environment can be ensured by reserve setting and robust optimization.
