A SIMULATION OF SOLAR ENERGY SYSTEM CONTROLLED BY P&O, IC AND FUZZY LOGIC USING BIDIRECTIONAL CHARGING OF BATTERY
Keywords:The photovoltaic system, MPPT methods, DC-DC convertor, Bi-directional battery charge, PI control
In this study, a simulation designs using a MATLAB is presenting to identify the characteristic of a solar energy panel as main feeding part, also, an alternative source represented by battery to compenstae the required missing energy on the load in case of low energy produced by a PV panel due to the effect of atmosphere condition on the solar energy in case of low radiation and temperature degree fall on it where a PV system as a whole works on feeding both of load and battery, but it may depend on the stored energy into the battery based on its capacity. In this purpose, different maximum power point techniques used in the PV system to extract the maximum energy. Perturb and Observe P& O, Incremental Conductance IC and Fuzzy Logic are the main common and modern techniques for tracking the maximum power.
