Aiming at the problem of high proportion of new energy consumption in Northeast China,the operation characteristics of wind-thermal power cogeneration system considering demand response are studied.The composition and structure of the cogeneration system,and the energy flow interaction are studied.Considering the demand response to construct a collaborative optimization strategy,explore the flexible resources in the domain,study the price and alternative demand response types,combine energy flow coupling and share energy storage units to construct a collaborative optimization mechanism,and use carbon flow characterization as an auxiliary decision.Then,a collaborative optimization model is established to analyze the synergistic regulatory effects of optimization strategies,with economic efficiency,wind power absorption rate,and carbon emissions as the objective functions.Through the simulation analysis of the actual regional system,the response of various demand-side resources to participate in the system regulation and control is studied.Meanwhile,the interaction of energy flow was analyzed by using carbon flow characterization,and the results verified the rationality and feasibility of the proposed strategy.
