Optimization of region energy system operation considering part-load characteristics of fuel cells

Proton exchange membrane fuel cells use hydrogen as fuel and have the advantage of being safe and efficient, important for the research and development of future energy systems. This paper addresses the problem of constant efficiency of PEMFC in most region energy systems, an optimization model considering the partial load characteristics of proton exchange membrane fuel cells is proposed. First refine the modeling of PEMFC in Sinmulink, obtain the power generation efficiency and waste heat recovery efficiency functions at different load rates, then the optimized operation model is established with the lowest typical daily operating cost and carbon emission cost as the objective function, Finally, the solution is performed by particle swarm algorithm. The algorithm shows that the proposed optimization model can effectively reduce operating costs as well as carbon dioxide emissions, which is more economical and environmentally friendly.
