Simulation and modelling of PV-wind-battery hybrid power system

As oil and coal reserves are being depleted whilst at the same time the energy demand is growing, it is important to consider alternative energy generating techniques. Similarly there is a move from centralized power generation to decentralized power generation. Specifically within rural communities where there is limited access to electricity, it is possible for decentralized renewable energy systems to make a large impact. This paper outlines the design of a hybrid power system consisting of solar photovoltaics (PV) power system, wind power system and battery storage. This system is designed for stand-alone operation. A novel controller links each of these components to ensure that one system is supplying the load dependant on the weather conditions. This system is modeled in Matlab Simulink and tested for various weather conditions and temperatures. The model and results are detailed in this paper.
