Renewable Energy Resources Modeling Survey

Abstract

Renewable energy resources (RES) have become multiple, which made the world interested in developing them because of their continuity, relieving pressure on fossil fuels, as well as the environmental impact. Using RERs will lessen reliance on conventional fossil fuel-based electrical power generation and is more ecologically friendly and eternally sustainable. In this paper, modelling of several renewable energy resources (RERs) including photovoltaic solar (PV), wind, hydro power, geothermal, biofuel, and battery power storage is presented. Modeling of these sources is very important because of their impact on the smart grid and because of their variable nature and different from the components of the traditional electrical network. For battery, the battery storage is very important because many RERs are not fixed in the amount of power generation or they are not sufficient for the loads. For hydro power, Water flows at different rates, small hydropower generators operate at different speeds. For geothermal, geothermal thermal energy includes drawing steam or warm water from wells buried kilometers under the surface of the Earth which is constantly changing. Burning a variety of biomass fuels, which after combustion are transformed into various kinds of energy, can provide sustainable biomass energy that is also unstable. This paper discusses the modelling of all of these resources as well as their benefits and drawbacks.
