This contribution presents experimental results on the short-circuit behavior of two grid-forming inverters, one commercial prototype and one experimental device.
In order to evaluate the efficiency, a model based on the equivalent circuit consisting of an ideal inverter, a series resistance, RS, (input series resistance) that represents the ohmic losses, and a parallel resistor, RP (output shunt resistance), which represents the self-consumption is used [12, 18].
Thus, for non-relevant generation plants to participate in voltage regulation, commercial hybrid inverter manufacturers have added new capabilities that allow them to inject/absorb reactive power into the grid by changing the power factor (PF) of the inverter.
Specifically, a parameter has been introduced to assess the dependence of the inverter efficiency’s dependency on the PF. Based on the experimental tests, this paper establishes a linear relationship between this parameter and the value of PF.
In this context, the presented paper studies the variation of the efficiency of a hybrid inverter system at different PF values. Both inductive and capacitive behaviour of the hybrid inverter has been tested. The test-bed system used in this paper is installed at the Storage X-Lab of Enel X of Catania (Italy).
Three different values of DC power have been considered. Experimental results show how the inverter efficiency decreases by only about 1% when varying the PF from 1 to 0.8, for both capacitive and inductive behaviours.
This contribution presents experimental results on the short-circuit behavior of two grid-forming inverters, one commercial prototype and one experimental device. Two different operation modes, grid-connected and islanded, have been investigated and the different requirements are discussed along the results.
