Abstract

The invention discloses a method for optimizing a wind power system-contained unit and backup configuration in the technical field of the operation and scheduling of an electric power system. The invention adopts a technical scheme that by analyzing the output characteristics of a fan, a valve point effect generated when a turbine inlet valve is suddenly opened is considered in a traditional method for analyzing the operation expense of a thermal power generating unit, and analysis on the rotary backup capacity based on the reliability index is also added; and a mathematic model for optimizing the unit and backup capacity is established, so that an optimal configuration result is obtained, and the configuration is carried out according to the configuration result. According to the method, different treatment ways of the water power in different periods are considered, and a favorable foundation is provided for the stable economical scheduling of the electric power system containing a wind power field; and the random fluctuation of the wind power is considered in the modeling process, a step for analyzing the rotary backup capacity based on the reliability index is added, the operation economical efficiency of the unit is combined with the optimized configuration of the rotary backup capacity, and a unit and backup optimization mathematic model containing the wind power field electric power system is established.

Description

technical field [0001] The invention belongs to the technical field of power system operation and scheduling, and in particular relates to an optimization method including wind power system units and backup configurations. Background technique [0002] In recent years, with the rapid development of the domestic power industry and the implementation of market-oriented reforms, my country's power system has developed rapidly. UHV AC / DC transmission has been put into operation, the installed capacity of traditional power sources and new energy power generation has grown steadily, and micro-grid and energy storage technologies have also made significant progress. Uncertainty factors are also increasing. In actual operation, due to the random outage of generators, load fluctuations, load forecast deviations, and line overloads, etc., the balance of the power system will be destroyed, which will bring great economic losses to the society. In terms of new energy power generation,...
