“…Mobile resources, e.g., portable energy storage and dispatchable electrified transportation have potentials to provide emergency response to extreme conditions [43,44], and mobility requires the plug-and-play operation of MGs. Although plug-and-play operation has been widely investigated from a physical-layer perspective [12,13,38], it has not been investigated from a cyber-layer especially under extreme conditions. Due to limited communication bandwidth, just one-way communication is designed, i.e., mobile DGs only receive the information from networked DGs that have pre-designed in the cyber-layer network.…”

This paper proposes a cyber-physical cooperative mitigation framework to enhance power systems resilience under extreme events, e.g., earthquakes and hurricanes. Extreme events can simultaneously damage the physicallayer electric power infrastructure and the cyber-layer communication facilities. Microgrid (MG) has been widely recognised as an effective physicallayer response to such events, however, the mitigation strategy in the cyber lay is yet to be fully investigated. Therefore, this paper proposes a resilience-oriented centralised-to-decentralised framework to maintain the power supply of critical loads such as hospitals, data centers, etc., under extreme events. For the resilient control, controller-to-controller (C2C) wireless network is utilised to form the emergency regional communication when centralised base station being compromised. Owing to the limited reliable bandwidth that reserved as a backup, the inevitable delays are dynamically minimised and used to guide the design of a discrete-time distributed control algorithm to maintain post-event power supply. The effectiveness of the cooperative cyber-physical mitigation framework is demonstrated through extensive simulations in MATLAB/Simulink.

“…In addition, the proposed sliding surface suffers from deviations due to the inevitably compromised regulation nature between the frequency and active power sharing schemes. To improve the resilience of the secondary voltage sharing schemes against parameter uncertainties and measurement noises, a fast terminal SMC algorithm in combination with a model-dependent Extended State Kalman-Bucy Filter (ESKBF) is presented by [13]. However, this scheme suffers from complexity associated with model-based algorithms, and it lacks consideration of power terms as well as frequency regulation into the proposed sliding surface.…”

“…To address the stated problem, a fully-distributed (also termed as distributed adaptive) consensus-based control strategy was reported in [31] for droop-based islanded AC microgrids. For the resilient operation of an autonomous microgrid comprising inverter-based DG units, a fast terminal sliding mode-based distributed secondary voltage control strategy was proposed in [32]. A Kalman-Bucy filter-based extended state observer was designed for accurate estimation of the state information of the extended DG model and counteract the disturbances resulting from three different sources: measurement noise, parameter variation and immeasurable external variables.…”

A Finite-Time Robust Distributed Cooperative Secondary Control Protocol for Droop-Based Islanded AC Microgrids

et al. 2021

In this research work, a resilient finite-time consensus-based distributed secondary control protocol is presented for droop-based distributed generating (DG) units of an islanded AC microgrid (MG). Through a multi-agent control structure, the DG units of the microgrid adjust their active power outputs so that they reach an agreed-upon value in a finite time. Concurrently, all the DG units are forced to operate with their frequencies regulated to the reference MG frequency in a finite time, despite time-varying load perturbations. Each DG unit is provided with a hierarchical control architecture, where the primary control is achieved using the droop control method, while the secondary control is established through the proposed distributed control protocol. The communication between DG units takes place over a sparse communication network. The proposed control protocol is robust to both small and sufficiently large communication latencies and it supports the plug-and-play feature of DG units. Different time-domain-based numerical simulations are carried out on a small as well as large microgrid testbenches in Matlab/Simulink and demonstrate the correctness and effectiveness of the proposed distributed control protocol. A comparative study is also presented with the existing distributed control protocol, and it is found that the proposed strategy is superior in its performance.
