Abstract

The invention discloses an operation control method and device for a fuel cell combined cooling heating and power system. The system is composed of a fuel cell combined cooling heating and power unit,a hydrogen supply system, a hot water tank heat storage unit, an absorption refrigerator, a demand predictor, an operation controller, a heat energy transmission and distribution controller and an energy metering device. According to the system operation control method, an operation strategy of each device in the system is formulated in combination with energy consumption prediction, the actual output and state of each device in the system are monitored in real time in actual operation, the operation strategy is adjusted in time, and cooperative power supply, heating and cooling of the fuel cell combined cooling heating and power system are realized. The device is composed of a demand predictor, an operation controller and a heat energy transmission and distribution controller so as to achieve the method.

Description

technical field [0001] The invention belongs to the technical field of multi-energy systems, and in particular relates to an operation control method and device for a fuel cell cogeneration system. Background technique [0002] Every milestone development of energy utilization in human history will open a new era. From firewood to coal to oil, human civilization has also advanced rapidly, and at the same time, it is increasingly inseparable from energy. At present, petrochemical energy sources such as coal and oil are facing depletion, and the environmental problems brought about by carbon emissions and global warming are constantly engulfing the living environment of human beings, and human civilization will face a major turning point. Efficiency, cleanliness and sustainability are the key elements in the choice of future energy sources, among which efficiency is a necessary condition. Efficiency means high energy density. Tracing the history of energy development, it is ...
