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...

Grid connected voltage source inverters (VSIs) are essential for the integration of the distributed energy resources. Hysteresis current control (HCC) is a commonly employed method for power control of VSIs. This control method, in contrast with voltage control, provides good dynamics, good stability and implicit over current protection. However, the most important concern of digital implementa...

The reduction of high harmonic content in the grid side current is achieved by different harmonic compensating techniques. In order to accomplish it, selective harmonic compensation is carried out in grid-connected photovoltaic inverters by means of resonant harmonic compensators. The harmonic compensator shown in this paper is lead lag compensator. This paper shows a systematic design procedur...

Growing energy demand and environmental consciousness have reevoked human interest in grid-connected photovoltaic (PV) systems. This work is focused on the modelling and simulation studies of the dynamic behaviour of a grid connected photovoltaic system. The model is implemented using MATLAB/Simulink with the SimPowerSystems Block Set. This work also presents the results of a comparative study ...

The parallel operation of inverters has many benefits, such as modularity and redundancy. However, the connection produces circulating currents that may result in malfunctions system. In this work, a control technique for elimination low-frequency components grid-connected is presented. proposed structure contains n − 1 zero-sequence loops, with being number connected parallel. Simulation exper...

In today’s and future’s electrical power grid system, regenerative energy sources like photovoltaic (PV) power systems consisting of PV panels and grid-connected inverters are very popular in domestic as well as in commercial power plants. High competitive pressure among PV power system providers due to cut inverter’s costs can be observed. Therefore different technical approaches have to be ev...

An open-end winding induction motor, fed by two 2-level inverters connected at either end produces space vector locations, identical to those of a conventional 3-level inverter. In this paper, two switching algorithms are proposed to implement space vector PWM for the dual inverter scheme. The proposed algorithms do not employ any look-up tables. The time consuming task of sector identification...

The connection of inverters for distributed generation photovoltaic systems to the distribution network creates situations of risk to the loads that are connected to the point of common coupling (PCC) and personals who maintain the power grid. A risk that should be avoided is the supply of electricity, by one or more inverters, to the distribution network after disconnecting the main power grid...
