The invention discloses a simulation calculation method for a Nash equilibrium point of an electricity market including multiple load agents. The electricity market is simulated based on a conjectured supply function equilibrium (CSFE) model, and profit of a load agent company comes from a result formed by subtracting the cost used by the load agents for scheduling electricity price type and excitation type load resources from a subsidy given by an electricity company after bid success. Based on features of electricity price type and excitation type loads, the cost of the load agents is a secondary function of output of the load agents, a bidding strategy limit compensation price is a primary function of the output, a bidding coefficient is determined by response conjecture variables of the agents for the market, the agents dynamically adjust their own bidding strategies through learning, after full competition, finally, the market reaches the Nash equilibrium point, an algorithm performs analog simulation on a bidding process of each time, the market gaming process when the multiple load agents appear in a specific market is fully represented, a clearing price of a market final balance state is obtained, and guidance is provided for construction of the electricity market and evaluation of resource utilization efficiency.
