Abstract

Power quality (PQ) is the prime constraint in grid-connected photovoltaic (PV) systems. In this paper, the reactive and active power controller is utilized with a three-phase grid-connected PV system to improve the PQ using seagull optimization algorithm (SOA). This proposed system comprises two key controllers as the Fly back converter with bacterial foraging optimization algorithm (BFOA) to track maximum power of PV panels and the suggested SOA optimized controller for the grid-integrated three-phase inverter. The grid integration of PV is utilizing a three-phase modular multilevel inverter, which manages the active and reactive powers by functioning the SOA optimized controller using the grid voltage. The novelty of the proposed system is to improve the PQ by utilizing the BFOA and SOA optimization algorithm for generating the maximum power and improve the active power from the non-linear PV. The proposed control strategy has to minimize power dropping into the inverter, by regulating the instantaneous active and reactive powers, for the improvement of PQ. Moreover, it can reduce the harmonic and reactive power compensation. The proposed system is established and replicated in the MATLAB/Simulink platform and its outcomes are examined and equated with existing methods.
