Power system scheduling method and system and storage medium

Abstract

The invention provides a power system scheduling method and system and a storage medium, and the method comprises the steps: constructing a power system economic scheduling model containing wind power, and determining a target function; inputting data such as installed capacities, economic parameters, climbing rates and the like of the wind turbine generator and each thermal power generating unit;performing scene generation and reduction on the wind power output based on a wind power model, and determining standby capacity; determining a unit combination scheme according to the load and the standby demand; calculating and solving a target function by adopting a particle swarm algorithm until a termination condition is met; and outputting the optimal particles as an optimal solution, and outputting the operation income of the power system. According to the invention, the power system economic scheduling model is established to adapt to a complex, open and competitive power market in the future; the development of clean energy is promoted, and more and more clean energy is merged into a power grid; and meanwhile, the particle swarm algorithm is applied to the power system economic scheduling model, and the prediction precision of the model is further improved.

Description

technical field [0001] The present invention relates to the field of electric power, in particular to a power system scheduling method, system and storage medium. Background technique [0002] Since the development of modern wind power technology in the 1970s, modern wind power technology has achieved remarkable results. In 1973, due to the global oil crisis, traditional fossil energy was non-renewable, and the combustion of traditional energy emitted a large amount of carbon dioxide, leading to a series of consequences such as global warming, which caused serious damage to the global ecological environment. Under this heavy pressure, people began to look for alternative energy sources. As a form of new energy with relatively mature technology and broad commercial application prospects, wind power generation has gradually attracted people's attention, and wind power resources have the advantages of abundant reserves and clean use. [0003] In the mid-to-late 1990s, wind po...
