In-depth mining of the adjustment capacity and value of demand-side load resources under the background of marketization is an important support for realizing the safe operation of the power grid and efficient operation of the power market in the future. This paper takes the load aggregator as the object, exploring its market operation ability through the main energy and ancillary service joint market simulation analysis. Firstly, the transaction framework of main energy market and frequency modulation ancillary service joint market considering load aggregators is built, then the market participation mode and the cost of each entity are analyzed. Secondly, based on the game equilibrium theory of oligopoly competition, a load aggregators included multi-period equilibrium model of energy and frequency modulation ancillary service joint market is established. Finally, the nonlinear complementarity method is applied to solve the model, and the rationality and effectiveness of the proposed model are verified through typical case analysis. The results show that with the participation of load aggregators, the effect of “peak shaving and valley filling” on both load and active power price is obvious, up and down frequency regulation capacity prices of the system have decreased, and the downward adjustment is more prominent, the purchase cost is reduced, and the user profit and social welfare can increase. It provides reference for future market planning as well as EVA operation.
