Multi-energy-flow strong-coupling ecological breeding whole-process combined heat and power supply method

Abstract

The invention discloses a multi-energy-flow strong-coupling ecological breeding whole-process combined heat and power supply method. The method comprises the steps that 1, performing model selection on an energy production module, an energy conversion module and an energy storage module in a combined heat and power supply system; 2, arranging an energy generation module and an energy conversion module near a load; 3, respectively modeling an energy generation module, an energy conversion module and an energy storage module in the combined heat and power supply system so as to construct a combined heat and power supply system model considering the whole ecological breeding process; and 4, performing two-stage random optimization scheduling by taking the lowest operation cost of the whole combined heat and power system as an objective function, taking output climbing and energy charging and discharging constraints of energy storage equipment of each unit as inequality constraints and taking system energy balance as an equality constraint. The multi-energy flow strong coupling ecological breeding whole-process combined heat and power system considering and covering a fluctuating powersupply and a cooling, heating and power load is built, gradient utilization of energy is achieved, and the primary energy utilization rate is increased.

Description

Technical field[0001]The invention belongs to the field of power supply and demand interaction, and in particular relates to a multi-energy flow strong coupling ecological farming whole process cogeneration method.Background technique[0002]With the continuous exploration of combined heat and power systems, the technology has become increasingly mature. However, to realize the improvement of the energy utilization rate of the combined heat and power system, it is still necessary to study the model of the combined heat and power system. The general combined heat and power system uses natural gas as fuel, and uses small gas turbines, gas internal combustion engines, micro-combustion engines and other equipment to first use the high-temperature flue gas obtained after natural gas combustion to generate electricity, and then use waste heat for heating in winter; in summer, drive absorption Refrigerators provide cooling; at the same time, it can provide domestic hot water.[0003]However, t...

Problems solved by technology

[0003] However, there is still a lack of modeling research on the combined heat and power system that considers the full use of local natural resources in the ecological breeding process, using biogas units and water source heat pumps as the main, and fluctuating power as the auxiliary.
