Refrigeration scheduling system and method by adopting back-pressure type cogeneration unit and wind-power output

Abstract

The invention discloses a refrigeration scheduling system and method by adopting a back-pressure type cogeneration unit and wind-power output. The method comprises the following steps of: by combined control of the back-pressure type cogeneration unit and refrigerating load, the equivalent generation of the wind power is adjusted to be consistent with the actual need of the system, so that the pressure of grid paralleling is reduced; a user adopts two modes for refrigeration, namely, a centralized heat-absorption type refrigerator and an air conditioner for power consumption; and under the condition that the power supply and the refrigeration supply are met, the hot-water flow supplied to the centralized heat-absorption type refrigerator is reduced and is compensated by consumption of power and refrigeration, the power generation output is also changed correspondingly, and the supply is met according to the change of power consumption load and the matching of the wind power generation. The change of the cogeneration output and the power consumption load condition of the user is adjusted by fluctuation of wind power generation, so that the matching between the equivalent output of the wind power generation at the user side and the wind power output needed by the system is realized.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of clean energy, and relates to a back pressure cogeneration unit and wind power output refrigeration scheduling system and method. Background technique [0002] Renewable energy has the characteristics of green and clean, and has developed rapidly in recent years. However, taking wind power generation as an example, while wind power generation provides clean and low-carbon energy, the large-scale grid connection of wind farms also has a negative impact on the safe and economic operation of the power grid. After the large-scale wind farm is connected to the grid, its output fluctuates greatly, and the power fluctuation is often opposite to the fluctuation trend of the electricity load. The anti-peak-shaving characteristics of wind power generation will further expand the peak-to-valley difference of the system, increase the difficulty of power grid dispatching, and have a series...
