Abstract:
The proton exchange membrane fuel cell(PEMFC) with hydrogen as the main fuel is a good clean energy utilization device.In order to meet the challenge of "carbon peaking and carbon neutrality goals",an integrated energy system model based on the hybrid energy storage of proton exchange membrane fuel cell and power-to-gas(P2G) and considering the uncertainties of wind power and photovoltaic output in the system is proposed. Firstly,the membrane fuel cell is finely modeled and analyzed. Secondly,the short-term prediction based on the wavelet transform-neural network is adopted for new energy sources such as wind power and photovoltaics;finally,a mixed integer linear programming model including the equipment operation and maintenance cost,real-time electricity price policies,and carbon penalty cost is established,while the system is constrained by safety and steady operation. The results of the numerical analysis for an industrial park show that the proposed optimization model considering new energy output and PEMFC-P2G hybrid energy storage can effectively reduce operating cost and carbon emission,and has excellent economy and environmental protection.
