“…These features have encouraged researchers to seek its application in the realm of LFC. SMC is widely used in the frequency control issues for integrated power systems in the presence of uncertainties and model inaccuracy [7], [14]- [16], [18]- [20], [22], [23]. The selection of sliding surface (such as proportional (P), integral (I) etc.)…”

In this paper, a decentralized load frequency control (LFC) is proposed for the frequency regulation of multi-area power systems applying optimized integral sliding mode control (OISMC) scheme. A modified particle swarm optimization (MPSO) algorithm is utilised to optimize the control variables of the proposed controller for improving the performance of frequency response. A comprehensive model of a multi-area power system is developed where each area is considered to power from conventional sources, renewable energy resources (RERs), and electrical vehicle (EV) aggregators. Different types of interconnectors have been considered to tie different power regions. This system is subjected to random generation and loading conditions, as well as model uncertainties, which cause its frequency and area control error (ACE) to deviate from their nominal values. A decentralised OISMC is implemented for the proposed model to keep the frequency variation within the nominal range. Further, a validation study investigates the performance of the proposed control technique in MATLAB simulation environment to mimic the real power system operation. This study includes different test scenarios considering the dynamic events such as variations in load demand, amount of generated power, participation factor of EV reserve, system parameters, disturbances, and time delay. The simulated results support better frequency regulation with the suggested OISMC compared to other alternative control approaches.

“…Conversely, most recent research has conducted a new control methodology called Sliding Mode Control (SMC). This control methodology comprises several types of controllers such as Twisting Sliding Mode Controller (TSMC), (STSMC) [1], (ASTSMC) [2], Integral Sliding Mode controller (ISMC) [3], higher-order SMCs [4,5], fractional-order global SMC [6], full order SMC [7], non-linear SMC [8,9], non-linear super TSMC [10], and smooth integral SMC [11]. Different orders of sliding mode controllers are implemented in the load frequency control issue, like Second Order SMC (SOSMC) and Third Order SMC (TOSMC) [12][13][14].…”

The constant changes in the load power lead permanently to a power mismatch between the power generation and the power consumption. So, the system frequency due to the power imbalance deviates from the nominal value. Consequently, a control loop should be implemented to stabilize the system frequency whenever a load change occurs. This paper presents a new super‐twisting sliding mode control methodology for obtaining an optimal frequency performance in a multi‐pool system. The paper presents a three‐pool system for frequency deviation problems using an optimal gain Super Twisting Sliding Mode Controller (STSMC), which regulates the frequency change and the line power change to zero in a minimal time. The extent of the excellence of the study proposed is evaluated by comparing it with three Benchmark classical controllers, which are the Tilt‐Integral‐Derivative (TID), Proportional‐Integral‐Derivative (PID), and Fractional‐Order PID (FOPID). The parameters of the four controllers are determined by a proposed physical meta‐heuristic optimization technique called Transient Search Optimizer (TSO), inspired by the dynamic behaviour in the electrical circuits comprising storage elements such as capacitors and inductors during the switching actions. The system simulation is performed, and the STSMC proved overwhelming superiority over other controllers, as it deals better with the transient interval of the system response. Renewable Energy sources (RESs) like photovoltaic and wind energy systems are established, and the STSMC is tested with industrial and residential load models. Finally, energy storage devices such as batteries and superconducting magnetic energy storage are implemented to suppress the rapid fluctuations in the system response, and it succeeded in doing that as the system oscillations are greatly damped with the energy storage devices.

“…e SMC is very important because of its robustness and resistance to large disturbances. e SMC has already been studied for the LFC of MAPS [10][11][12][13][14][15][16][17][18][19][20]. Over time, several methods have been combined with the MAPS SMC to handle the LFC problem of MAPS.…”

“…In [19], the controller parameter is determined using grey wolf optimization and particle swarm optimization approaches to get an ideal outcome in a sliding mode controller for frequency management in an interconnected power system. Because of the discontinuous control component in [20], the traditional integral SMC suffers the flaw of chattering. However, the above conventional SMC methods were applied for the LFC of MAPS consisting of thermal plants or hydro alone in each area without considering the mismatched disturbance and load variation.…”

Recently, to balance the increased electricity demands and total generated power, the multiarea power system (MAPS) has been introduced with multipower sources such as gas, nuclear, hydro, and thermal, which will impact the load frequency control (LFC). Therefore, the LFC of the two-area gas-hydro-thermal power system (TAGHTPS) is introduced by applying the single-phase sliding mode control-based state observer (SPSMCBSO). In this scheme, the TAGHTPS is the first model that considers the uncertainties of the parameters in the state and the interconnected matrix. Second, the state observer is employed to estimate the state variables for the feedback control. Third, the SPSMCBSO is developed to modify the basic sliding mode control to improve the performance of TAGHTPS in terms of overshoot and settling time. In addition, the SPSMCBSO is established to rely fully on the state observer so that the difficulty in the state variable measurement is solved. Fourth, the TAGHTPS stability analysis is performed using a new linear matrix inequality (LMI) scheme—Lyapunov stability theory. Lastly, the simulation results are shown and compared to recently established classical control methods to validate the SPSMCBSO choice of application for the LFC of the multiarea multisource power system (MAMSPS).
