Optimal Scheduling of Load Aggregators Participating in Demand Response Market under Low-Carbon Power System

Abstract

To address the increasingly urgent issues of global energy security and environmental degradation, General Secretary Xi Jinping has proposed the “dual carbon” goal and the construction of a new power system dominated by new energy sources. It is one of the important ways to promote low carbon energy transition and achieve “dual carbon” goal to construct the demand response market transaction mode of load aggregator under new power system. Therefore, this paper puts forward a dispatching method for load aggregators to participate in the demand response market under the low-carbon power system, and gives some policy suggestions for load aggregators to participate in the demand response market under the low-carbon power system. Firstly, in the framework of the low-carbon power system, the definition of load aggregator is given, and the market function, technical function, voltage level limit, load response capacity requirement, grid access specification and technical standard of grid safety are analyzed. Second, research the load aggregators to participate in demand response market framework, combined with the new peak power system design cut demand response scenario, with the lowest cost of power grid operation, peak sharpening effect is best, at the same time meet the target of minimum carbon emissions, establish the low-carbon power system under load aggregators in optimal operation model of response to market demand; Finally, taking the receiving end system of China's low-carbon power as an example, the numerical simulation and analysis are carried out to prove the scientific nature of the optimal dispatching method of the load aggregator participating in the demand response market under the low-carbon power.
