Power management strategies for a stand-alone power system using renewable energy sources and hydrogen storage

摘要: A stand-alone power system based on a photovoltaic array and wind generators that stores the excessive energy from renewable sources (RES) in form of hydrogen via water electrolysis for future use polymer electrolyte membrane (PEM) fuel cell is currently operation at Neo Olvio Xanthi, Greece. Efficient management strategies (PMSs) have been developed. The PMSs assessed their capacity to meet load requirements through effective utilization electrolyzer under variable generation RES (solar wind). evaluation PMS has performed simulated experiments with anticipated conditions over typical four-month time period region installation. key decision factors are level provided by state charge (SOC) accumulator. Therefore, operating policies production consumption depend excess or shortage SOC. parametric sensitivity analysis investigates influence major variables such as minimum SOC characteristics performance integrated system.
