Smart inverter-based PV-STATCOM power Compensation using BaPhin optimization Algorithm

Abstract

Photovoltaic (PV) solar farms are typically resting at nighttime with their entire expensive assets unused, in which the PV-STATCOM can be utilized to provide voltage control during critical system needs on a 24/7 basis. In the nighttime, the entire inverter capacity is utilized for STATCOM operation. This research developed a smart optimized inverter for reactive power compensation in the distributed grid systems, and new optimized controller for current regulation, voltage regulation, reactive power control, and power factor regulation. The PV-STATCOM controller is optimized using the proposed BaPhin algorithm, which will compensate the voltage, current, real, and reactive power in the distribution system.One of the FACTS devices, the static synchronous compensator (STATCOM), controls the voltage-current components and balances the reactive power in the power system. The voltage, current, power factor, reactive power in the grid-connected PV system as well as in the inverter is regulated by the proposed BaPhin optimization algorithm, which optimally adjusts the proportional controller in the regulators. The performance of the proposed method is more effective in the reactive power compensation than the existing methods.
