Abstract: Distributed generation is an important method to accumulating the energies from different sources. It has not impacted the environmental conditions along with to mitigate the transmission losses. In this regard, battery banks are performance very imperative role in the solar system for suppressing the power fluctuations and enhance the power quality. Moreover, various control techniques are essential to the PV-battery system because of rendering the continuous power flow during random load variation. This paper mainly focused on complete control and power organization system (CAPMS) with a hybrid fuzzy-PI controller for PV battery bank based on AC and DC buses in micro-grid operations. The proposed CAPMS improve the dynamic response of the system under extensive operating conditions. Also, it has controlled the DC and AC bus voltages and eccentricity of the frequency of the system. The proposed hybrid fuzzy PI system has an ability of improving the system stability compared with conventional PI controller. The simulation is approved out by Matlab/Simulink as well as compares the performance of the proposed approach with other conventional controllers.
