Abstract

The invention discloses an optimal scheduling method and system for a photovoltaic power system based on a flexible load. The response characteristics of the flexible load are combined, and the minimum operating cost, carbon emission penalty cost and lost load risk cost are taken as objective functions, so that the random fuzzy constraint conditions are determined, the photovoltaic output is predicted and a model is solved by adopting an improved bacterial colony chemotaxis algorithm based on a satisfaction method. The method or the system can meet the requirements for safe, economic and environment-friendly operation of an electric power system, the absorptive capacity of the photovoltaic system is greatly improved, the adopted algorithm has better convergence, the optimization result ismore ideal, and a reference is provided for a decision maker to carry out scheme decision.

Description

technical field [0001] The invention relates to the field of optimal scheduling of power systems, in particular to a method and system for optimal scheduling of photovoltaic power systems based on flexible loads. Background technique [0002] Photovoltaic power generation has become one of the most potential new energy power generation methods, but due to the circadian periodicity of sunlight, the influence of the environment and meteorological conditions, it has greater intermittent and randomness. For large power grids, photovoltaic The power generation system is a typical uncontrollable source, and the uncertainty of its output power will bring great impact to the large power grid. Therefore, in order to meet the requirements of power system safety, economical operation and power supply quality, it is self-evident to optimize the scheduling of the photovoltaic power system. Contents of the invention [0003] The purpose of the present invention is to provide a flexible...
