| Summary: | Renewable energy sources such as solar and wind system are the most affordable energy sources compared to conventional sources. Both energy sources can be connected to support and supply the demand and act as a backup energy sources for locations that are not fitted with any electricity distribution system. Furthermore, these clean energy sources have minimum operational cost and can reduce the dependency on conventional sources due to decrease the release of harmful greenhouse gases polluting the environment. The main problem and challenges that hinder the sustainability of renewable energy sources is voltage fluctuations that may lead to violation solar system and wind generation. Weather event is strongly affecting the solar system and wind generation. This fluctuation will be influencing the energy and stability of the power generation system. Therefore, the purpose of this project is to manage the combination of PV, wind, microturbine and the battery in the stand-alone system in order to ensure the continuity of supply and the optimal Non-Renewable energy utilization can be achieved. Besides, the cost of Microturbine energy generation is targeted to be reduced. Actual data from power supply by Solar (PV) is utilized in this project. The energy management in the hybrid PV-wind and microturbine stand-alone system are able to increase the operation efficiency thus maximizing the battery lifespan by keeping the State of Charge (SoC) at 90% or higher than that. State of charge level control is critical for extending battery life, minimizing power fade, and preventing over draining of battery energy. |
