Abstract

The variability of RESs and their intermittent output power against the stochastic energy consumption, especially for standalone hybrid power systems, have spurred the development of new long-term energy storage solutions for improving the reliability in remote areas. Currently, the reliability of remote area hybrid standalone energy systems is affected due to the absence of long-term energy storage systems, as existing systems include batteries that are not capable of ensuring short-term reliability. Hence, there is an ongoing discussion on solar-powered water electrolysis systems to produce and store hydrogen utilizing excess generation, which can later be to generate electricity through fuel cells for providing long-term storage solutions. Though new long-term hydrogen storage solutions can improve the reliability, the optimal utilization of different components of remote area hybrid energy systems having solar photovoltaic systems, batteries, electrolyzers, hydrogen tanks, fuel cells; is a complex issue and the overall techno-economic benefits will be significantly affected if the energy coordination among different components is not properly carried out. This paper proposes a rule-based energy management system (RL-EMS) for appropriately coordinating energy in remote area hybrid energy systems and determining optimal sizes of different components so that the overall system cost is reduced while meeting the supply-demand balance. Simulations are conducted to validate the effectiveness of the proposed RL-EMS under changing power supply and load demand conditions. The simulation results confirm that the RL-EMS assist in meeting continuously changing load demands (with a maximum load of 20 kW) through a 20 kW solar PV, 5 kW battery, 10 kW fuel cell, 12 kW electrolyzer, and a 10 kg hydrogen tank, while achieving a minimum levelized cost of electricity of $0.2743 per kWh and improving the reliability.
