This paper presents a unique application of continuous mixed -norm (CMPN) algorithm-based adaptivemanagement strategy with the aim of enhancing the low voltage ride through (LVRT) the capability of grid-connectedelectrical phenomenon (PV) power plants. The PV arrays are connected to the purpose of common coupling through a DCDC boost converter, a DC-link capacitor, a grid side inverter, and a three-phase step up transformer. The DC-DC converteris used for a maximum power point tracking operation based on the fractional open circuit voltage method. The grid-sideinverter is utilized to control the DC-link voltage and terminal voltage at the PCC through a vector control scheme. TheCMPN algorithm-based adaptive proportional-integral (PI) controller is used to control the power electronic circuits due toits very fast convergence. The proposed algorithm updates the PI controller gains online without the need to fine tune oroptimize. The effectiveness of the proposed control strategy is compared with that obtained using Taguchi approach- basedan optimal PI controller taking into account subjecting the system to symmetrical, unsymmetrical faults, and unsuccessfulreclosing of circuit breakers due to the existence of the permanent fault.
