What is a microgrid (MG) system?

School of Electrical, Computer, and Telecommunications, University of Wollongong, Wollongong, NSW 2522, Australia Author to whom correspondence should be addressed. The microgrid (MG) system is a controlled and supervised power system consisting of renewable energy (RE)-based distributed generation (DG) units, loads, and energy storage.

What is a microgrid system?

The microgrid (MG) system is a controlled and supervised power system consisting of RE-based DG units, loads, and/or energy storage that can be operated either autonomously or in grid-connected mode [ 3, 4, 5 ]. Under grid-tied operation, the MG injects or absorbs power from the grid according to the actual condition of the RE-based generator.

What causes small-signal stability in microgrids?

Stability in microgrid [ 11, 30 ]. Small-signal stability in MGs can arise from various sources such as continuous fluctuations of the RE-based system, the feedback controller, the small change in load, parameter variations, and a lack of damping due to the low-inertia characteristics of MG [ 11 ].

What is resonance assessment in MGs?

6.3. Resonance Assessment in MGs Autonomous and grid-tied operation of MGs leads to the occurrence of interactions such as interaction among DG units within the MG, the resonance between the MG and series compensator devices, and coupling between LCL filters of DG units and line impedance.
