Abstract: This paper presents the optimal design and simulation of a grid-connected Photovoltaic (PV) system to supply electric power to meet the energy demand by Electrical Department in University of Tripoli Libya. Solar radiation is the key factor determining electricity produced by photovoltaic (PV) systems. This paper is designed to develop a novel method to calculate the solar photovoltaic generation capacity on the basis of Mean Global Solar Radiation data available for Tripoli Libya and finally develop a system design of possible plant capacity for the available roof area. MatLab/Simulink Programming tools and monthly average solar radiation data are used for this design and simulation. The specifications of equipments are provided based on the availability of the components in the market. Simulation results and analyses are presented to validate the proposed system configuration.
Abstract: This paper investigates the energy storage
technologies that can potentially enhance the use of solar energy.
Water electrolysis systems are seen as the principal means of
producing a large amount of hydrogen in the future. Starting from the
analysis of the models of the system components, a complete
simulation model was realized in the Matlab-Simulink environment.
Results of the numerical simulations are provided. The operation of
electrolysis and photovoltaic array combination is verified at various
insulation levels. It is pointed out that solar cell arrays and
electrolysers are producing the expected results with solar energy
inputs that are continuously varying.
