Abstract :
Renewable energy sources are an attractive
alternative option for augmenting the supply that comes
from the utility Grid. This is because they are
environmentally friendly. However Photovoltaic power
generation is intermittent in nature. Hence, it is usually
combined with energy storage systems such as batteries.
In this study, pumped hydroelectric energy storage is
used for supplementing the power produced from the
Solar Photovoltaic system especially during peak
demands and when the solar irradiance is low especially
at night. Thus, the objective of this study is to model
and simulate a pumped energy storage hydro system
that can provide power supply of up to approximately
100 kW for a 10 hour period to service the night time.
The proposed system is modeled using MATLAB
Simulink. A total volume of 91836.7 m3 of storage water
was calculated to achieve this purpose. Maximum
torque of about 90 N/m was attainable when the angular
speed of the water turbine was between 1100 and 1200
rpm. Recommendation for further works can be
considered to maintain the angular speed of the turbine
within this range.
