This paper presents a model predictive control (MPC) of a utility interactive (UI) single phase inverter (SPI) for a photovoltaic (PV) system at residential/distribution level. The proposed model uses single-phase phase locked loop (PLL) to synchronize SPI with the grid and performs MPC control in a dq reference frame. SPI model consists of boost converter (BC), maximum power point tracking (MP...

Solar energy sources are widely available, but in the form of DC source. It is connected in distribution system by means of converting DC/AC supply. It is achieved by means of inverter. To get efficient AC source we use multilevel inverter (MLI). The popularly used inverter is cascaded H-bridge MLI. As the step increases, the AC output nearly becomes same as sinusoidal. The purpose of the proje...
