Abstract

In this research work, design and analysis of BESS multiport DC-AC converter with DPPC Integrated by using FLC is implemented. The unavailability of power supply from solar PV is not uniform throughout the day. So, a battery is integrated with Solar PV. The obtained dc power from the integrated system needs to supply to the loads as well as to the grids. But the loads needs AC supply. So, a multiport ac-dc converter along with differential power processor is employed. The pulses to the MPC is given by Modified Space Vector Pulse Width Modulation Technique (SVPWM) that takes use of fluctuations in solar and battery voltage. In this project mainly, the control of active power flow is attained. In the controlling topology of MPC, PI controller is implemented to regulate the reference voltage by giving current and reference currents as inputs. But by implementing of PI controller will have less speed response of the system and high harmonic distortions. In order to overcome these issues, this paper proposes a novel controlling topology named Fuzzy Logic Controller (FLC). This will enhances the speed response of the system by maintaining good power quality. The evaluation of this system is considered in two cases namely constant irradiation and variable irradiation by using Matlab/Simulink 2018a Software.
