Combined heat and power scheduling method for improving wind power consumption and based on cooperative game

Abstract

The invention discloses a combined heat and power scheduling method for improving wind power consumption and based on a cooperative game. The combined heat and power scheduling method comprises the steps that a cooperative game model of a heat power plant, a wind power plant and a thermal power plant is constructed, and a participant operation strategy is given; then the expected economic benefitunder the cooperative game is analyzed; a maximum net benefit model of participants is established, and a benefit distribution model under the cooperative game is calculated; then a boiler start-stopcontrol strategy and a thermal storage device heat-storage heat-release model are constructed through the residual thermal space and the wind abandoning electric quantity; and finally, dynamic inertiaweight and a compression factor improved particle swarm optimization algorithm is introduced to solves the model. The combined heat and power scheduling method for improving the wind power consumption and based on the cooperative game can improve the benefit of the participants and improve the utilization rate of the wind power while ensuring the operational reliability of a system. In the cooperative game, the benefit of the participants can be improved and the wind power utilization rate is increased.

Description

technical field [0001] The invention relates to the field of dispatching of large power grids, in particular to a combined heat and power dispatching method based on cooperative game to improve wind power consumption. Background technique [0002] With the extensive development and use of traditional fossil energy, problems such as resource shortage, environmental pollution, and climate change have become increasingly prominent. In order to solve energy and environmental problems as a whole and break the bottleneck of economic and social development, wind energy has attracted widespread attention due to its economic reliability, clean environmental protection, and sustainable utilization. However, the uncertainty and volatility of wind power itself have brought many adverse effects on the safe operation and normal dispatch of wind power connected to the grid. [0003] Some areas are rich in wind energy resources, but in the winter heating period, thermal power units are usu...
