Abstract

The invention discloses a method and device for regulating power generation and utilization resources of a self-contained power plant. An energy consumption adjustment model and a response model of output of a generator set of a self-contained power plant, an energy consumption adjustment model and a response model of an adjustable load of an enterprise power utilization side, and an energy consumption adjustment model and a response model of an energy storage device are pre-constructed; to acquire a self-contained power plant unit regulation energy consumption model, a self-contained power plant total response model and a self-contained power plant total response frequency. An optimal power generation and utilization resource regulation strategy is solved by taking the minimum power generation and utilization resource regulation energy consumption, the shortest response time and the minimum response frequency of the self-contained power plant as optimization objectives. The adjustable power generation and utilization resources of the self-contained power plant are comprehensively considered and comprise a generator, a adjustable load and a energy storage device. Three devices areequivalent to integrally participate in demand response, the demand response potential of the self-contained power plant is fully excavated, and the peak regulation burden of the power grid is remarkably reduced.

Description

technical field [0001] The invention belongs to the technical field of power systems and automation thereof, and in particular relates to a control method and device for power generation and consumption resources of a self-provided power plant. Background technique [0002] Captive power plants refer to power plants built by enterprises to meet their own electricity needs. The self-provided power plant generates power according to the criteria of meeting the production needs of the unit, and purchases part of the power from the grid when the self-use is insufficient. The opposite is a utility plant, a power plant that provides electricity to the public. The current self-provided power plant management mode and means can no longer meet the relevant requirements for standardized management and flexible participation in transactions of self-provided power plants under the new situation. Functional realization in areas such as new energy consumption, and put forward operable m...
