Is there a finite-time event-triggered frequency control for Islanded AC microgrids?
The performance of the proposed finite-time event-triggered frequency control is verified utilizing a hardware-in-the-loop experimental testbed which simulates an AC MG in Opal-RT. This paper proposes a finite-time event-triggered secondary frequency and voltage control for islanded AC microgrids (MGs) in a distributed fashion.
How to control the frequency of a microgrid with distributed generation sources?
In this section, the frequency model of a microgrid with various distributed generation sources is first implemented to control the microgrid frequency. The proposed RANFIS controller is designed to reduce fluctuations in the microgrid frequency compared to other controllers.
What is the frequency control strategy for a hybrid stand-alone microgrid?
In this paper, the frequency control strategy is designed for a hybrid stand-alone microgrid, which is robust against load disturbances, variations in weather conditions, and uncertainties in the microgrid parameters. The proposed intelligent control scheme relies on the Recurrent Adaptive Neuro Fuzzy Inference System (RANFIS).
How do we control the frequency of Islanded microgrids?
In the context of controlling the frequency of islanded microgrids, a common approach involves employing droop control based on active-frequency power droop characteristics.
How does a microgrid work?
When connected to the grid, the microgrid's frequency and power are functions of the main grid and only need to be controlled for the power of the units, but on islands, the microgrid's frequency and voltage fluctuate need an independent control 3, 4.
How can ranfis control the frequency of a microgrid?
Our proposed control strategy is based on the Recurrent Adaptive Neuro-Fuzzy Inference System (RANFIS). This controller can dynamically adjust the active power output, thereby assisting in frequency control within the microgrid.
