Abstract

The invention discloses a method and equipment for optimizing dynamic economic dispatching of a power system. Sewage data, build a hybrid dynamic economic dispatch model of the power system; according to the improved Sailfish optimization algorithm and the hybrid dynamic economic dispatch model, determine the output power distribution results of the power system generators, where the position update formula of the improved Sailfish optimization algorithm It is determined by the weight inertia, global search formula and Levi's flight strategy; the output power distribution result of the generator set of the power system is output. The sailfish optimization algorithm is improved by introducing weight inertia, global search formula and Levi's flight strategy to improve the algorithm's optimization ability and convergence speed, thereby improving the optimization effect of power system dynamic economic dispatch optimization.

Description

technical field [0001] The application belongs to the technical field of electric power systems, and in particular relates to a dynamic economic dispatch optimization method and equipment for electric power systems. Background technique [0002] There are a large number of renewable energy sources in the power system, so their operation is random and uncertain to a certain extent, which will increase the difficulty of economic dispatch. Therefore, dynamic economic dispatch (Dynamic Economic Dispatch, DED) of power system is one of the important links of power system operation. How to take into account the instability of renewable energy, not only to ensure the normal operation of the power system, but also to make a reasonable load distribution plan, is a research hotspot in the field of dynamic economic dispatch of power grids. [0003] In the prior art, sailfish optimization algorithm, particle swarm optimization algorithm, etc. are often used to optimize the dynamic econ...
