Impact of Green Hydrogen Power Generation on HRES for Rural Area including EV and Home Loads

The use of renewable energy as the new normal is becoming one of the recent developments of the present century, and this trend is supposed to continue, since the increasing energy demand throughout the world, and excessive reliance on fossil fuels in power systems and energy generation has led to environmental pollution. Green hydrogen-based power generation including photovoltaic and wind hybrid renewable energy systems (HRES) are the most effective and perfect solution in these cases. Green hydrogen-based solar power has been the most promising and yielding of the alternatives that are available to us, and hence it has been a bright idea to study and work on utilizing solar resources to provide required power in the electrolysis process and also to HRES system. Along with solar, we have used wind resources to supplement solar energy. But, the disadvantage of solar and wind energy is that, they are intermittent in nature. A green hydrogen source is added to this system to solve this problem, to ensure that there is an unlimited energy supply. The objective of this paper is to provide the modeling and optimal sizing of a hybrid energy system to satisfy the electricity demand for a region in Siliguri, located in WB, India. HOMER Pro software has been used to model a green hydrogen-based Renewable Energy System (HRES), keeping in mind the component constraints (capacity, cost and emissions). Different case studies have been considered, to improve the efficiency and reduce the costs of operation.
