In autonomous microgrids, the well-known frequency and voltage droop control are extensively used to share active and reactive powers among parallel inverters without using any communication infrastructure. However, power sharing is performed at the

In low-inertia microgrids (MGs), one of the major challenges is the large frequency drop in case of active load increment. There has been presented an appropriate approach to tackle this issue, which is the virtual synchronous generator (VSG) control

Autor: S.M.T. Bathaee, Mahmoud Mollayousefi Zadeh, Zakaria Afshar

Publikováno v: 2019 IEEE International Conference on Environment and Electrical Engineering and 2019 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe).

In this paper, the switching command is produced by a sliding mode controller so that inverter output current follows the load current. To this end, an appropriate sliding surface for inverter output current is first defined, whereby control law is d
