Abstract
There is a shortage of power supply in multi provincial power grid during peak load period. The response speed of interruptible load is fast, and it has the same excellent regulation performance as the standby on the generation side, which can meet the needs of fast transfer. Aiming at the situation of interruptible load participating in the joint market under the bilateral mode, this paper designs the joint clearing process of electric energy and reserve market considering interruptible load, and establishes the joint clearing model considering interruptible load participating in electric energy and reserve market with the goal of maximizing social welfare. Simulation results verify the effectiveness of the proposed model.

Summary
There is a shortage of power supply during peak load period in many provinces. Step 2: Taking the maximization of social benefits as the optimization objective, considering the generation side and user side volume price curves, system source load balance constraints, reserve capacity constraints, upper and lower limits of generator output, line power flow constraints, load characteristic constraints and other constraints of the electric energy market and reserve capacity market, the unit commitment (SCUC) with safety constraints is cleared, and the start and stop of the 24 hours is calculated Plan. Step 3: on the basis of known unit start-up and shutdown scheme, considering other related constraints besides unit start-up and shut-down constraints, the sced clearing with safety constraints is carried out, and the clearing results of joint optimization of electric energy and standby auxiliary services are calculated, so as to realize the economic distribution of load and generator output under the standby capacity market. Through the technical support system, SCUC and sced algorithms are used to optimize the calculation based on the declaration information of market participants and the grid operation boundary conditions on the operation day, and the day ahead market transaction results are obtained
