Energy control and size optimization of a small-scale hybrid renewable energy system with combination of storage systems

Abstract:

Several rural electrification projects in remote areas have been implemented, however sizing is a complex task due to meteorological variables and the type of control strategies. This article analyzes the impact of different combinations of energy storage or hybrid storage systems for a small-scale renewable generation system composed of biomass-based generators and/or photovoltaic panels backed by diesel generators, three types of storage technology are considered, lead acid battery, lithium and fuel cells this with the help of an analysis software for renewable systems in order to check whether this hybrid system could be more economical than a renewable generation system backed by a single storage technology. The charge tracking (LF) control strategy and with a single storage technology gets the best results, the level cost of energy is {\} 0.122 dollars, while with Li-ion batteries and the same control strategy the cost of kWh is {\} 0.326
