The invention provides a power market power generator balanced quotation method and system compatible with different load levels. The method comprises the following steps: summarizing and calculating a power generation cost function through a physical acquisition system, determining a supply function game model, selecting a decision variable and a non-strategy variable, and issuing load parameter information in a power transaction center; according to decision variables, non-strategy variables and load parameter information, a double-layer optimization model is established for each load level appearing in the market, and a corresponding equilibrium point is solved by using an EPEC model conversion method; based on the balance points, a quotation curve passing through the balance points under various load levels is obtained through a connection crossing mode; and carrying out equilibrium property test and iterative judgment on the quotation curve. According to the method, the final quotation curve of the power
