“…Several control and optimization techniques have been applied to RES control problems and challenges 19‐21 . Sliding control theory is a powerful, robust, and high‐speed technique to damp any oscillations at the system dynamic performance and to handle nonlinear processed systems 22,23 . Another advantage is the estimation ability to both of system disturbance and states, which enhances considerably the overall dynamic performance under any defined disturbance 24 .…”

This article presents a novel control technique of Jaya-based super-sliding controller that is applied on superconducting magnetic energy storage system (SCMES). The SCMES will be integrated to operate with tidal turbine generators (TTGs). The penetration of TTGs has recently grown due to distributed generation contributions to the energy sector. To alleviate the potential system instability due to TTG dynamic performance, SCMES is connected to TTG to support the dynamic operational conditions. SCMES is implemented to act quickly during both cases of power generation and absorption, so it can realize any required mismatch between the supply and load power at dynamic transient periods. To enhance such capability, this article proposes the application of Jaya-based super-sliding control technique to control and tune the system dynamic gains. The proposed technique implements incorporated cooperative algorithms using enhanced Jaya competitive algorithm and super-sliding method to facilitate the exchange of energy between the SCMES, the TTG, and the power network. It allows smooth dynamic performance, power quality enhancement, and robust dynamic reference tracking. Jaya-based super-sliding controller is developed and proposed for accurate and reliable control and tunning of system parameters. The proposed controller ensures the superb performance of the synergy of SCMESs and TTGs. Digital simulations have validated the effectiveness of the proposed system with the optimal dynamic parameters and minimization of the global control error.

“…Recently, PVECSs have attracted the researchers all over the world due to its widespread availability at free of cost, no consumption of any material, no type of pollution, less space required and its fast development for power delivery. The researchers have focused on fast dynamics, minimisation of integration effect on the grid, optimum power flow, simple control algorithm and compact configuration [5, 6]. However, an optimum power fed to the grid and control of the grid voltage distortion is yet a great challenge.…”

“…A major drawback of DS‐SMC is the chattering phenomenon, which leads to variable switching in the converter [15]. In [17, 19] many solutions can be found to stabilise the switching frequency. In carrier‐based pulse‐width modulation (PWM) or space vector pulse‐width modulation (SVPWM), the modulation index can be considered as a continuous control input.…”

This study proposes a control technique based on integral switching surface sliding‐mode control for three‐phase pulse‐width modulation (PWM) rectifier. The proposed control system is based on the combination of a conventional proportional–integral (PI) controller and with two decoupled first‐order sliding‐mode (PI‐FOSM) current controller. A set of integral switching surfaces based on the state‐space equation are designed in the internal loop to force the grid currents to track their desired values. The proposed control approach improves the transient response and minimises the steady‐state error under uncertainty. In addition, a conventional PI controller is also employed for the voltage regulation loop and generating the current reference of inner loops. In the controller design, all parameters of the system are considered with bounded perturbations in the design of control law. The main advantage of the proposed controller is robustness property against variations of entertained PWM rectifier parameters and external disturbances. The proposed PI‐FOSM can improve transient performance and can decrease of the harmonic components under steady‐state condition. In order to validate the theoretical contributions of this study, the performance of the proposed controller has been investigated by using a prototype laboratory.
