Abstract: Multi-fuel economic scheduling with valve point effect is a typical high-dimensional, non-convex, non-linear and non-differentiable optimization problem in power system operation control. In order to solve the problem, the existing technique is easy to fall into the local optimal value, the convergence precision is not high and the computational efficiency is low. Based on the standard difference algorithm, the algorithm improves the computational efficiency and the precision of the standard differential algorithm by solving the problem of gene editing. And the algorithm is applied to the simulation and analysis of the multi-fuel power system of 10 units and 40 units respectively. In addition, comparing the simulation results with the optimization results of a variety of algorithms, the results show that the proposed standard differential algorithm not only can greatly reduce the search space through the fusion gene editing operation, but also effectively alleviate the premature phenomenon of the algorithm, calculate better time in the calculation time.
