The use of renewable energy sources is increasing and will play an important role in the future power systems. The unpredictable and fluctuating nature of solar power leads to a need for energy storage as the prevalence increases. Photovoltaic (PV) is a method of generating electrical power by converting solar radiation into direct current electricity using semiconductor that exhibit the photovoltaic effect. The method is used to implement and determine the characteristic of a particular photovoltaic cell panel and to study the influence of different values of solar radiation at different temperatures concerning performance of photovoltaic cells. This model it can be used for build a photovoltaic circuit model for any photovoltaic array. An MPPT (maximum power point tracking) algorithm using DC/DC converter (Boost converter) is applied to make PV arrays to work at maximum power point. Then, the system behaviour and performance are studied. The simulation results of MATLAB/SIMULINK address that the proposed PI controller has a good performance. This validated model contributes to a better sizing of PV panel and battery energy storage for the small and medium standalone PV system. Power smoothing efficiency is demonstrated with different battery module sizes. Changing the power smoothing algorithm parameters to suit the battery capacity is shown to be effective in providing as good smoothing as possible within battery constraints.
