Abstract: Hyperbolic secant cost function based least mean square (HSLMS) algorithm is presented in this article to improve the performance of a three-phase single-stage gridconnected photovoltaic system (GCPVS) to improve its overall performance under adverse circumstances. The nonlinear loads at the distribution end pose a number of power quality challenges for the integration of distributed energy resources like solar photovoltaic (PV) energy. Nonlinearity, disturbances, and unbalanced loads cause these uncertainties. The key objective of this article is to operate the GCPVS to extract maximum PV power and solves the current related PQ problems. The characteristics of the hyperbolic secant cost function are employed to generate sinusoidal grid reference currents for harmonics mitigation, zero reactive power burden on the distribution grid, and to achieve unity power factor (UPF) mode of operation. The presented control structure is simulated in MATLAB/Simulink for analyzing the behavior of GCPVS during uncertain conditions.
