Active Islanding Detection with Parallel Inverters in Microgrid

The most widely used technique for islanding detection is the passive is-landing detection method. However, conventional passive methods have wider non-detection zone (NDZ) area. Failure to detect unintentional islanding events impose various issues like voltage & frequency instability, power quality degradation, protective devices malfunctioning, equipment damage, and threats to line workers. This paper presents active islanding detection for parallel inverters in AC microgrid in which the effects of d-axis and q-axis disturbance current injection are analysed and compared. Further, the outcomes of current injection at different parameters through multiple inverters have been shown and discussed. The simulation results of the active islanding detection are obtained using MATLAB/Simulink.

In a microgrid, distributed generations (DGs) such as solar photovoltaic and energy storages(ESs)... more In a microgrid, distributed generations (DGs) such as solar photovoltaic and energy storages(ESs) are interfaced with the AC network through power electronic-based inverters. Due to the low inertia of the solar photovoltaic system, the inverter controls become crucial for improving the power quality. State-of-theart conventional droop control in the inverters face problems such as large voltage and frequency deviations and improper reactive power sharing during various contingencies. This paper presents a simulation model of a stand-alone microgrid with solar photovoltaic source with an enhanced droop control technique which is able to mitigate the constraints of conventional droop control. In order to improve the transient response and appropriate reactive power sharing, proposed control technique explores the addition of derivative of active power for the frequency droop control and the rms output voltage from the inverter for the reactive power control. The simulation results of the proposed controller are obtained and compared with the conventional droop control methods using MATLAB/Simulink.
