Smart Inverter-Based PV-STATCOM Power Compensation using BaPhin Optimization Algorithm

In the Photovoltaic (PV) Solar farms the whole expensive resources are kept unused, while the PV-STATCOM one of the FACTS device is still be active at all time to provide voltage control even at the critical system needs, on a 24/7 basis. For the functioning of STATCOM at the night time the inverter capacity is used. This research developed a smart optimized inverter for reactive power compensation in the distributed grid systems, and a new optimized controller for current regulation, voltage regulation, reactive power control, and power factor regulation. The PV-STATCOM controller is optimized using the BaPhin algorithm, which compensates for the voltage, current, real, and reactive power in the distribution system and also it effectively tunes the parameters included in the controller. The static synchronous compensator (STATCOM), controls the voltage-current components and balances the reactive power in the power system. The current, power factor, voltage, and reactive power in the grid-connected PVsystem as well as in the inverter is regulated by the BaPhin optimization algorithm, which optimally adjusts the proportional controller in the regulators. The performance of the BaPhin method is more effective in reactive power compensation than the existing methods. The attained results of the BaPhin method in the reactive power compensation that achieved the values of 500V at 0.49 sec, 0.0097 at 0.49 sec, and 1.0093A concerning DC link voltage, DC, and Quadrature current. The active, reactive, and power factor of the BaPhin algorithm is measured that achieved 98.73kW, -0.329KVAR,1 concerning grid 90.7944kw, -13.3753 kVAR, 0.9998 in 0.5 sec concerning inverter, 84.369kw, -5.1345KVAR,1 concerning load.
