A direct coupling hydrogen production system consisting of a photovoltaic (PV) cell and a proton exchange membrane (PEM) electrolyzer is established. The expression of the hydrogen production efficiency is derived and the general performance characteristics are revealed. The number of series‐parallel connected PV cell is optimized using the hydrogen production effficiency of the system as objection...
This paper develops an iterative searching method to find the optimal power management strategy and component sizes for a hybrid power system that consists of a proton exchange membrane fuel cell, a chemical hydrogen production system, photovoltaic arrays, and a Li-Fe secondary battery set. In order to find the most suitable power management and component sizes, we build a MATLAB/SimPowerSystem simulation...
The ability to track the optimum of dynamic environments is important in many practical applications. In this paper, the capability of a hybrid genetic algorithm (HGA) to track the optimum in some dynamic environments is investigated for different functional dimensions, update frequencies, and displacement strengths in different types of dynamic environments. Experimental results are reported by using...
The cooling tower is a significant device of the circular cooling water system in thermal power plants, whose cooling performance will directly affect the operation stability of steam-turbine unit and the efficiency of cold-end system. As the construction and development of thermal power plants, especially nuclear power plants and solar power plants, the requirement for the construction cost of cooling...
