Abstract: This research presents a unique configuration to enhance the efficiency of a hybrid photovoltaic-battery energy system.The system combines a fuzzy logic PID controller to control the DC bus voltage with a three-level inverter (3LI) and three-level boost converter (3LBC) to achieve optimal energy consumption.To achieve maximum power extraction from the solar generator and maintain capacitor voltage balancing, a double-loop control system employs a perturbation and observation (P&O) algorithm for maximum power point tracking (MPPT) and proportional integral (PI) regulators.Furthermore, a three-level inverter NPC guarantees effective power transmission to the AC load.In the event of a power imbalance due to fluctuations in solar radiation or an AC load, a buck-boost converter (BBC) facilitates bidirectional energy transfer between the DC connection and the battery energy storage (BES).The PID controller uses a fuzzy logic controller (FLC) to determine its parameters.The study shows that using simulations on the MATLAB/SIMULINK platform to test the 3LBC and the fuzzy PID (FPID) controller can get rid of total harmonic distortion (THD) and improve system performance.
