“…In this portion, the stability and the robustness of the NI-PR controller are accomplished in the presence of symmetrical three lines to ground (3LG) fault and unsymmetrical single line to ground (1LG) fault. Here, 3LG and 1LG faults are considered as 3LG is the most severe and 1LG is the most common fault in power system (Islam et al 2019(Islam et al , 2020a. The faults are considered in the system with a time span of 100 ms (t = 0.22-0.23 s).…”

This paper demonstrates the design of robust proportional resonant (PR) controller using negative imaginary (NI) theorem for voltage control of three-phase islanded microgrid (MG) application. While operating MG as the islanded mode, different types of random and unknown load dynamics affect the MG. These loads eventually deteriorate the proper execution of MG-inducing disturbances in voltage and current. Therefore, to improve the performance of the three-phase MG, a simple, second-order controller is designed with the combination of NI theory and PR (NI-PR) controller. This controller is capable of providing higher level of damping as well as excellent stability properties. The stability and effectiveness of this controller are examined through imposing uncertainties, in terms of several load dynamics as well as different fault conditions. The comparison with respect to linear quadratic regulator and model predictive controller also ascertains the robustness of the designed controller. The NI-PR controller and the system are simulated in MATLAB/SIMULINK platform. Keywords Islanded microgrid • Negative imaginary theory • Second-order controller • Voltage control • Robust performance 1 Introduction Keeping the pace with progressive advanced facilities, demand for energy is rising lavishly. But due to the environmental protection, depletion of fossil fuel and sustainable development resulted in critical need for a cleaner energy technology (Bouchebbat and Gherbi 2017; Islam et al. 2020c). Hence, renewable energy sources are playing a vital role in today's power system applications. Some popular renewable energy sources are wind energy, photovoltaic (PV) system, biomass, wave energy, hydro-power, etc. (Coelho et al. 2018). Renewable energy sources-based distributed generators (DGs) are mainly small-scale power generation

“…26 There are several types of NSFCLs, [22][23][24][28][29][30][31][32] which also known as solid-state FCLs (SSFCLs), and bridge-type FCL (BFCL) is one of them. 22,27,33 The BFCL is one of the most commonly used NSFCLs as it provides excellent responses with exceptionally simple structure and extremely easy functioning during grid faults 22,[34][35][36][37][38] and hence, it can be used to improve the transient performance of hybrid power systems.…”

A nonlinear backstepping control scheme is proposed in this work for a bridge type fault current limiter (BFCL) in a hybrid power system for enhancing its transient performance. The hybrid power system has the provision to supply AC loads connected to the main grid and local DC loads. The DC-side of that system is coupled with AC-side through a bidirectional converter having power exchange capability between both AC-and DC-sides. The AC-side is coupled with the main grid through transmission lines and the BFCL is placed on the transmission line, where the faults are considered, as the transmission line is the most vulnerable point. The dynamical model of the BFCL is used to design the nonlinear backstepping controller (BSC) where the control input is derived in a way that it can ensure as well as enhance the transient performance of that hybrid power system. Lyapunov stability theory is used to theoretically demonstrate the stability of the BFCL using the proposed BSC. Theoretical findings guarantee the system stability, and simulation studies clearly indicate the superiority of the proposed BSC based BFCL (BSC-BFCL), both graphically and numerically over an existing nonlinear sliding mode controller (SMC) for the BFCL (SMC-BFCL), for symmetrical and unsymmetrical fault scenarios (both temporary and permanent type). In addition, percentage overshoot and settling time analyses suggest the lesser deviation of system responses during transients from their ideal values and quicker stability, respectively. Moreover, the astonishing total harmonic distortion (THD) values with the proposed technique signify the excellency over its competitors in every aspect.

“…Also, the cooperative control schemes require an appropriate software control algorithm combined with the FCLs to boost the performance of the FCLs. Over the years, different types of controllers have been used with different FCLs [19,21,29,30,32,[37][38][39][40][41][42][43][44]. The controllers can be initially classified into two categories, i.e.…”

“…They rely directly on the deviation of different system parameters such as voltage, current, and active power to detect the fault and activate the FCLs. Some of the conventional controllers implemented with different FCLs are discussed in various literature over the years [19, 21, 29, 30, 37].…”

Doubly-fed induction generators (DFIGs) have drawn prominent interest in the field of wind power generation, but they are vulnerable to grid faults. Grid codes mandate DFIGs to employ a sort of fault ride-through (FRT) technique during faults. Fault current limiters (FCLs) always help to augment the FRT capability of DFIGs and a non-linear controller boosts their performances. In this study, a non-linear auto-regressive moving average-L2 (NARMA-L2) controller-based bridge-type flux coupling non-superconducting FCL (BFC-NSFCL) is proposed to enhance the FRT capability of the wind farm. The authors analysed the performance of the proposed NARMA-L2-based BFC-NSFCL (NL2-BFC-NSFCL) against that of the conventionally used series dynamic braking resistor (SDBR), bridge-type FCL (BFCL), and proportional-integral (PI) controller-based BFC-NSFCL (PI-BFC-NSFCL). They tested the performance of the NL2-BFC-NSFCL through multiple temporary and permanent fault scenarios and carried out the mathematical and graphical analysis in MATLAB/Simulink platform. They found that the proposed NL2-BFC-NSFCL's performance surpasses the performances of the SDBR, the BFCL, and the PI-BFC-NSFCL. Moreover, the NL2-BFC-NSFCL has faster system recovery capability after the occurrence of any fault than other competitors.
