6 FAQs about [Microgrid fault-tolerant control]

Is there a fault-tolerant control scheme for DC Islanded microgrids?

In this paper, an active fault-tolerant control scheme is proposed for DC islanded microgrids subjected to sensor fault and external disturbance. Firstly, a distributed H ∞ observer is designed to estimate the uncorrupted voltage and current with high accuracy.

Can a distributed secondary consensus-based fault-tolerant control method overcome faults in MG?

Proposed distributed secondary consensus-based Fault-Tolerant control (FTC) method In this paper, the FTC method is proposed to overcome the impacts of faults in the MG based on a distributed consensus control method. The proposed controller can restore the system frequency, voltage, active and reactive power -sharing between DGs in MG.

What is fault tolerant control?

Fault Tolerant Control The estimated faults in C.T/P.T are used for corrections in the faulty sensors’ (transformers) readings to avoid the wrong current/voltage readings to calculate the instantaneous powers and correspondingly generation of wrong PWM signals.

What are additive faults/disturbances in microgrid system?

The additive faults/disturbances are considered in the system, such that the sensor output is added up with different sinusoidal faults/disturbances, which compositely form the complete mathematical model of the faults actually occurring in the C.Ts/P.Ts. 2.2. Mathematical Model of Microgrid System

Can a sliding-mode observer detect faults in a voltage source converter based microgrid?

This work investigates sensor fault diagnostics and fault-tolerant control for a voltage source converter based microgrid (model) using a sliding-mode observer. It aims to provide a diagnosis of multiple faults (i.e., magnitude, phase, and harmonics) occurring simultaneously or individually in current/potential transformers.

Does secondary consensus FTC work in multi-agent microgrid?

Evaluating the performance of the proposed secondary consensus FTC method in the MG. This paper proposes a distributed secondary consensus fault-tolerant control (FTC) method for the multi-agent microgrid (MG). The proposed controller is applied to compensate for the errors in the system frequency and voltage profiles in the presence of MG faults.
