BACKGROUND RESEARCH 
The project focuses on the combination of wind, solar, Genset and energy storing systems for 
sustainable power generation. The wind turbine output power varies with the wind speed at different 
conditions. The solar energy also varies with the hourly, daily and seasonal variation of solar 
irradiation. Thus, a generator-set system with a battery bank (energy storage bank) can be integrated 
with the wind turbine(s) and PV-system to ensure that the system performs under all conditions. The 
dynamic model, design and simulation of a Genset-Solar-Wind hybrid power generation system 
together with storage bank and with power flow controllers will be proposed. In the proposed system, 
when the wind speed is sufficient, the wind turbine can meet the load demand. When there is enough 
energy from the sun, the load demands can be supplied from the PV-array system. Whenever there is 
excess supply from the RESs, the energy storage bank stores energy, which will be used at times 
when there are insufficient supplies from the RESs. If either the available power from the wind 
turbine or from the solar panels cannot satisfy the load demand, the Genset system can meet the 
excess power demand.
The project will investigate for the best design layout (connection topology); to size the system 
elements appropriately; to design different models and simulate for the different power management 
strategies (PMS) which are defined for the system of the HPSs, which consists of renewable energy 
sources (PV-arrays and wind generator), conventional backup energy source (diesel engine generator) 
and energy storage bank (battery bank) to sustainably and efficiently satisfy the energy demand of 
remote site.
