“…A critically important task of this system is to carry out load frequency control (LFC), which aims to keep the frequency stable, say, by decreasing the unfavorable impacts on frequency caused by load disturbances. Since the 1970s, many studies have focused on the LFC problems of power systems providing different solutions [1][2][3][4][5][6]. Among them, proportional-integral-differential (PID) control and proportional-integral (PI) control are the most widely used.…”

“…To cope with the load perturbations and provide adequate damping to the system oscillations, Guha et al [3] proposed a fractional-order PID controller. In [6], a novel fractionalorder PID plus second-order derivative controller for LFC was designed. However, the classical control has some disadvantages, including long frequency stability time, large transient frequency deviation, and so on.…”

The attacks on power systems have been happening all the time, and gradually changing from a single attack to hybrid multiple cyber attacks. Such hybrid attacks may cause more catastrophic damages to the security and safety of multi‐area power systems. Here, the security control problem is analyzed for multi‐area power systems under hybrid cyber attacks. Two Lyapunov–Krasovskii functionals are constructed, and by utilizing the second‐order canonical Bessel–Legendre inequality, sufficient conditions are derived for stability criteria under resilient event‐triggered mechanism. A bound with H∞$H_{\infty }$ security performance is obtained under hybrid cyber attacks. A proper controller is synthesized to ensure that the trajectory of the multi‐area power systems can be driven onto the prescribed sliding surface. Finally, numerical examples and simulated results demonstrate the effectiveness and correctness of the proposed scheme.

“…Both the controllers are optimized by various metaheuristic techniques for comparison purposes and among all trader optimization‐based FOPID controller is found to be the most optimal controller among all. Khokhar et al 15 have presented a novel fractional‐order proportional integral derivative plus second‐order derivative (FOPID+DD) controller for LFC of similar type of HPS considering multiple non‐linearities like generation rate constraint, governer dead band, and time delay. H ∞ controller in a thermal power system with EV aggregator has been considered by Pham et al 16 for primary as well as secondary frequency control action.…”

Summary A considerable number of intermittent renewable resources like photovoltaic generation and wind energy when integrated into the conventional grid technology causes serious issues in the power systems like frequency instability. So an intelligent controller is desired for steady and reliable operation of the electric grid. This paper deals with the frequency control of hybrid power system (HPS) employing a sine cosine adopted Harris' hawks optimization (SCaHHO) technique. The proposed technique aims at improving the performance of the original Harris' hawks optimization (HHO) algorithm by incorporating a sine and cosine function in the calculation of escaping energy and chances of escaping of prey respectively to emphasize the exploitation process of hawks. The effectiveness of the SCaHHO technique is validated with the novel HHO technique as well as moth flame optimization, sine cosine algorithm, grey wolf optimization, salp swarm algorithm and gravitational search algorithm using 23 standard test functions. A non‐parametric statistical investigation is also carried out to verify the effectiveness of the suggested technique. Later the SCaHHO technique is utilized to tune a newly proposed adaptive fuzzy proportional integral derivative controller (AFPID) for frequency control of HPS. The suggested SCaHHO‐tuned AFPID controller achieves an improved control action by moderating the frequency fluctuations as compared to the PID controller. Hardware‐in‐loop validation of the proposed load frequency control scheme is also carried out using OPAL‐RT to measure its fidelity with the numerical simulation results.

“…The results indicated that the designed controller has better performance compared to the conventional controllers. Observer-aided resilient hybrid fractional-order and fractional-order proportional-integral-derivative plus second-order derivative controllers for load frequency control were studied in Guha et al (2021) and Khokhar et al (2021), respectively. Furthermore, Abdul Latif et al (2021) reviewed a fractionalorder controllers' optimization for load frequency stabilization.…”

The current study presented a novel single-input control technique, called the single-input interval type-2 fractional-order fuzzy (SIT2FOF) controller. This controller is suitable for the control problems in which the plant deals with hard external disturbance and model uncertainties. Fractional calculus and interval type-2 fuzzy sets are considered as two seminal parts of the SIT2FOF controller which provide robust control performance. In addition, single-input interval type-2 fuzzy (SIT2F) sets in the structure of the proposed controller reduce computational efforts and the number of tuning parameters. Accordingly, the controller can be implemented and tuned easily. Thus, the control problem of an automatic voltage regulator in a power system and a Kubota M110X tractor active suspension system were considered as case studies to validate the suggested method. To this end, simulations were performed in three scenarios, followed by comparing the proposed technique in each scenario with single-input type-1 fuzzy (ST1F), single-input type-1 fractional-order fuzzy (ST1FOF), and single-input interval type-2 fuzzy (SIT2F) controllers. The results revealed that the SIT2FOF control technique can significantly handle external disturbances and model uncertainties more efficiently compared to the other controllers.
