Combined refrigeration system by fuel gas combined cycle and solar power generation and scheduling method thereof

Abstract

The invention discloses a combined refrigeration system by a fuel gas combined cycle and solar power generation and a scheduling method thereof. A user adopts two ways including a centralized heat absorption type refrigerator and an air conditioner to consume electric power to refrigerate, wherein cold water is obtained by converting hot water of a fuel gas combined cycle unit through using the centralized heat absorption type refrigerator after the hot water is output and the electric power is supplied by the fuel gas combined cycle unit and a solar generator unit; under the condition of assuring the electric power supply and the refrigeration supply, and a water flow of the hot water which is supplied to the centralized heat absorption type refrigerator is reduced and is compensated by consuming the electric power to refrigerate; and a generated output is correspondingly changed and is supplied according to the change of a power load and the matching of the solar power generation. The output of the heat and the power and the change of the power load of the user are adjusted by the wave property of the solar power generation and the equal detection period and adjusting period areutilized, so that an equivalent smooth output at the user side by the solar power generation can be realized.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of clean energy, and relates to a gas combined cycle and solar 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. However, taking solar power generation as an example, while solar power generation provides clean and low-carbon energy, the large-scale grid connection of solar farms also has a negative impact on the safe and economic operation of the power grid. After the large-scale solar 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 solar power generation will further expand the peak-to-valley difference of the system, increase the difficulty of grid dispatching, and have a series ...

AI Technical Summary

Problems solved by technology

The anti-peaking characteristics of solar power generation will lead to further expansion of the peak-valley difference of the system, increasing the difficulty of power grid dispatching, and will have a series of impacts on power grid dispatching operation, voltage control, and power grid peak regulation.

Due to the imperfection of relevant research, the phenomenon of energy abandonment is serious
