With an increasing number of inverter-interfaced generators (IIGs), the power system is undergoing massive shifts toward electronic dominated system. Such paradigm change poses significant challenges to existing fault analysis theory and protection system, as a result disparate short-circuit response. Given this, needs be further investigated expanded address issues arising from new grid paradi...

The proposed DVSI scheme consists of two ...

This paper presents a soft-switching DC-DC boost converter, which can be utilized in renewable energy systems such as photovoltaic array, and wind turbine connections to infinite bus of a big power network, using grid connected inverters. In the proposed topology for the DC-DC boost converter, the main and the auxiliary power switches are turned on and turned off with zero voltage switching (ZV...

The paper presents common mode voltage analysis of single phase grid connected photovoltaic inverter. Many researchers proposed different grid tie inverters for applications like domestic powering, street lighting, water pumping, cooling and heating applications. Traditional grid tie PV inverter uses either a line frequency or a high frequency transformer between the inverter and grid. The tran...

The multiple parallel inverters have more than one resonant frequency influenced by many factors, which tends to result in stability and power quality problems. This paper develops the multiple input multiple output model of the grid-connected inverters system using the closed-loop transfer function. The influence factors of resonant characteristics are analyzed with the developed model. The an...
