Photo-hydrogen fuel cell heat and power cogeneration system, capacity configuration method and medium

Abstract

The invention discloses a photo-hydrogen fuel cell heat and power cogeneration system, a capacity configuration method and a medium. The system comprises a control center, a photovoltaic array, a fuel cell, an electrolytic bath, an electric heating device, an inverter, a hydrogen storage tank and a heat storage tank. According to the capacity configuration method, the microgrid capacity planning takes the optimal cost as the target, and meanwhile, the light abandoning amount, the power shortage amount and the heat shortage amount are included into a target function in the form of penalty terms to achieve stable energy supply; the medium is a medium which is loaded and executed by the processor to realize capacity configuration of the photo-hydrogen fuel cell. According to the invention, electric energy supply can be satisfied when photovoltaic power generation is small or no illumination exists, and the economical efficiency is better.

Description

technical field [0001] The invention belongs to the field of combined heat and power supply of photovoltaic hydrogen fuel cells, in particular to a combined heat and power supply system of photovoltaic hydrogen fuel cells, a capacity configuration method and a medium. Background technique [0002] By the end of 2020, the global installed photovoltaic capacity will reach 750GW, and the installed capacity of distributed power generation in my country will reach 252GW. As the penetration rate of distributed power generation in large-scale interconnected power grids increases, the ability of the system to cope with extreme climatic conditions is getting weaker and weaker. For example, in August 2020, the state of California in the United States was affected by extreme high temperature weather, and implemented zonal power curtailment measures to ensure the stable energy supply of the California power grid. In December 2020, extreme cold weather occurred in southern my country, an...

AI Technical Summary

Problems solved by technology

The power generation efficiency of the fuel cell can reach 50%-60%, and the remaining hydrogen energy is converted into heat energy. If this part of the waste heat is collected and utilized, the overall efficiency can reach 85%-95%. Otherwise, because the proton exchange membrane is not resistant to high temperature, special The cooling fan of the fuel cell will dissipate heat, which will further reduce the power efficiency
