Standalone (off-grid) renewable energy systems supply electricity in places where there is no access to the standard electrical grid. These systems can include photovoltaic generators, wind turbines, hydro turbines, or any other renewable electrical generator. Usually this kind of systems includes electricity storage (commonly, lead-acid batteries, but also other types of storage such as lithium batteries, other battery technologies, supercapacitors, and hydrogen). In some cases, a backup generator (usually powered by fossil fuel) is part of the hybrid system.
The modelling of the components, the control of the system, and the simulation of the performance of the whole system is necessary to evaluate the system technically and economically. The optimization of the sizing and/or the control is also an important task in this kind of system.
Taking into account all the above, this Special Issue is dedicated to any topic related to ‘’Standalone Renewable Energy Systems’’, including modelling, control, sizing, simulation, and optimization, considering both technical and economic aspects.
