The study evaluates the performance of an inverter control in a single-phase grid-linked PV scheme, focusing on addressing issues like transient response, voltage overshoot, harmonics and steady-state error. . Abstract: Grid-connected photovoltaic systems require a control technique to minimize the Total Harmonic Distortion (THD) in current and voltage. In this work, the Proportional Integral (PI) Controller is proposed. The inverter employs sinusoidal pulse-width modulation (SPWM) with a 10 kHz triangular carrier to precisely control four IGBT switches. . In this paper, an improved control method is proposed by introducing a compensation unit. The compensation unit can effectively compensate the system's phase around the crossover frequency, greatly enhancing the system's phase margin and stability. It is also capable of handling weak-grid. . ith current-regulated PWM are used to synchronize DG sources with the utility grid.
