The development in grid connected three phase inverter has increased the importance of achieving low distortion and high quality current waveform. This paper describes a method of reducing current ripple in a three phase grid connected inverter utilizing Proportional Resonance (PR) controller. The effectiveness of the PR current controller is demonstrated by comparing its performance with that of...
With the increasing penetration of photovoltaic generation systems in the grid, the use of grid-connected photovoltaic converters for reactive power compensation has been proposed to increase the utilization of the system's voltage source converter. Power factor correction and voltage regulation at the point of common coupling are among the proposed methods. This paper presents the modeling and simulation...
Photovoltaic (PV) energy is one of the fastest growing renewable energy resources. Most PV units are connected to the distribution or transmission grid by voltage source converters (VSC). As the number and size of grid-connected PV units increase, the requirements placed on them by grid operators are changing. Among the new requirements by some grid codes is that PV units should help with voltage...
