Simulation of Single-Phase on-Grid Photovoltaic Inverter for Power Injection and Active Power Filter

A New Control Method for Single-Phase Grid-Connected Inverter Using Instantaneous Power Theory

Because of installation for local consumers and since it is free of all contaminations, connecting photovoltaic cells to the grid via single-phase inverter is significantly on the rise. In this paper, a new simple current control is proposed for a single-phase grid-connected voltage source inverter. Using the PQ theory and modelling a single-phase system as an unbalanced three-phase system, a m...

A Novel Control Strategy for a Single-phase Grid-connected Power Injection System

In this paper, a novel and simple control strategy, based on state feedback method is suggested to control the power injection system (PIS). The considered PIS is composed of, a DC voltage source, a voltage source inverter (VSI) and a L-C-L filter. The DC source includes the battery source with boosted voltage. The battery can be charged with photovoltaic cells. Since, the grid voltage acts as ...
