DESIGN AND MODELLING OF HYBRID PV-MINI HYDRO POWER PLANT CASE STUDY NYAGAK MINI HYDRO POWER PLANT.
West Nile is currently under the Rural Electrification program of Uganda with WENRECo as the sole power system operator. However, there is an increased demand on the WENRECo network during wet seasons and reduced water levels on the Nyagak River that have resulted in a 1MW power deficit in the region. Hence there is a need for increased generation to support the existing hydro power plant so as to meet the power deficit. A 1.5MWp solar power plant was optimised, designed and modelled to mitigate this power deficit. Using DIgSILENT Power Factory 15.0, a load flow analysis was carried out to optimise the location of the solar plant. The simulation results showed that Koboko is the optimal location because a power plant at this location will result in increased power generation, improved voltage profile and reduced active power losses. Since the solar plant utilises inverters, there was need for a harmonic analysis to be carried out. This analysis showed the voltage distortion levels were within an acceptable range specified by the IEEE-519-2014 standards, hence no need to use filters. The project also includes a financial analysis which clearly shows that the project will break-even in less than four years after its implementation. (1.136Mb)
