Problems solved by technology

For example, the wind power grid in Inner Mongolia can operate at full load during the day, but at night when the electricity load is low, in order to ensure the electricity consumption of urban residents, the wind power has to take the measure of "abandoning wind", which is a pity

Embodiment Construction

[0088] The combined refrigeration system of water source heat pump and wind power generation and its dispatching method provided by the present invention, on the supply side, the power is jointly provided by thermal power generators and wind power generators, and the hot water of the water source heat pump is supplied to the centralized heat absorption refrigerator for refrigeration and transportation Cold water, users use cooling fan coil to consume cold water to provide cold air and air conditioner power consumption for cooling. Based on historical testing, predict the energy supply and energy consumption in the future to reduce the power consumption of cooling water for cooling In this way, compared with the volatility of wind power generation, the user's electricity load also has room for adjustment. Power-consuming refrigeration can not only compensate for the lack of cold water cooling, but also increase the load during low-power periods, and use it for cooling and hot wat...

Abstract

The invention discloses a water source heat pump and wind power generation combined refrigeration system and a scheduling method thereof. A user adopts a refrigeration fan coil method and a heat pump power consumption method for refrigeration. The user adopts the refrigeration fan coil method and an air conditioner power consumption method for refrigeration. After a comprehensive scheduling control device detects energy supply and user energy consumption situation at a certain period, a prediction is made for a future certain period; on the premise that power supply and refrigeration supply are satisfied, the hot water flow of a refrigeration centralized heat-absorbing-type refrigerator is reduced, the refrigerating capacity in shortage is compensated through refrigeration by consuming power, and the refrigeration by consuming power not only can compensate the deficiency of cooling water refrigeration, but also can increase the power load at a valley period; and in combination with wind power generation and heat and power cogeneration, the heat and power output and the change of user power consumption load are regulated according to the fluctuation of wind power generation, and through equal detection cycles and regulation cycles, the goal of user-side smooth output equivalent to wind power is realized.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of clean energy, and relates to a water source heat pump and wind power combined refrigeration system and a scheduling method thereof. Background technique [0002] Renewable energy has the characteristics of green and clean, and has developed rapidly in recent years. But taking wind power as an example, while wind power provides clean and low-carbon energy, the large-scale grid connection of wind farms has also brought adverse effects on the safe and economic operation of the grid. After large-scale wind farms are connected to the grid, due to their large output fluctuations, and power fluctuations are often opposite to the fluctuation trend of electricity load, that is, there is no wind available during peak load periods, and abundant wind energy appears during low load periods. The anti-peak-shaving characteristics of wind power will further expand the peak-to-valley differen...
