计及灵活性资源的综合能源系统源荷协调优化调度OA北大核心CSTPCD

The uncertainty and volatility of renewable energy and loads pose enormous challenges to the safe and flexible operation of integrated energy systems(IES).In order to improve the flexible adjustment ability of IES and the consumption level of renewable energy,this paper proposes an IES source-load coordination optimization scheduling method considering flexible resources.According to the operational flexibility requirements of the system,the flexibility capabilities of various resources are finely described.A joint operating model of combined heating and power(CHP)unit and hydrogen fuel cell(HFC)is established at the source-side according to the operating characteristics of the electric-hydrogen coupling unit,and a comprehensive flexible supply model of system is constructed at the load-side with consideration of the flexible supply capacity of comprehensive demand response.Two scheduling modes is divided according to the vacancy of operation flexibility at different times,and an optimal scheduling model based on IES flexibility constraints is constructed.A simulation analysis is carried out,and the simulation results show that the proposed optimal scheduling method can effectively improve the flexible adjustment ability of IES and the consumption level of renewable energy.
