The invention discloses an electric power system economic emission scheduling method based on collaborative normalization, which comprises the following steps of A, generating M candidate solutions, and calculating the fuel oil cost, the waste gas emission amount and the constraint violation amount of the candidate solutions; B, carrying out collaborative normalization processing on the candidatesolutions; C, selecting the candidate solution with the minimum penalty function value as the optimal solution; D, if the constraint violation quantity of the optimal solution is 0, determining that the optimal solution is the optimal power system economic emission scheduling scheme meeting all constraint conditions, and otherwise, repeating the steps A to C. According to the method, the physicalquantity line, the magnitude order and the improvement potential difference between the fuel oil cost and the waste gas emission are eliminated through a collaborative normalization method, the problem that cost saving and pollution reduction are difficult to achieve at the same time in the power generation process is effectively solved, the electric energy utilization rate is increased, and the power supply and demand balance is guaranteed.
