Synchronverters are inverters that mimic the behavior of synchronous generators. In this paper, we propose modifications to the synchronverter algorithm to improve its stability and performance. The proposed modifications are implemented in software and do not require any changes in the inverter hardware. The first two modifications concern the control of the virtual field current in the synchronverter...
We investigate the stability of a microgrid composed of two identical synchronous generators, inductive lines and resistive loads, without using any model reduction for “fast” variables. We derive sufficient conditions for local exponential stability, with a region of attraction that includes any initial state such that the states of the generators are sufficiently close to each other. This implies...
Synchronverters are inverters that mimic the behavior of synchronous generators. In this paper, we propose five modifications to the synchronverter algorithm from the paper “Synchronverters: Inverters that mimic synchronous generators,” (IEEE Trans. Ind. Electron., vol. 58, no. 4, pp. 1259–1267, Apr. 2011), to improve its stability and performance. These modifications are implemented in software and...
