Stabilisateur De Système d'ALIMENTATION Robuste Basé Sur Un Contrôle H∞ Structuré Pour La Stabilité d'UN Système Multi-Machine

“…The sliding mode control (SMC) is presented in paper [5], a farmland fertility algorithm (FFA) in [6] but the FFA is highly reliant on accurate and extensive data which can be challenging to acquire, a genetic algorithm in [7] which requires many iterations and evaluations, making it slow for complex problems like multi-machine system, a particle swarm optimization (PSO) in [8] but this algorithm performance critically depends on fine-tuning parameters, making it complex and less robust, a chaotic sunflower optimization algorithm in [9] which requiring careful tuning of chaotic parameters, struggles with local optima, prioritizing exploitation (refining good solutions) over exploration (finding new, potentially better regions) leading to missed global optima, a moth search algorithm in [10] but it lacks the rigorous mathematical backing of some established optimization methods, raising concerns about stability and global convergence guarantees, bio-inspired algorithms in [11] which is highly dependent on fine-tuning specific parameters, impacting effectiveness and requiring more expertise, a sliding mode control in [12]. Moreover, artificial intelligence-based training and tuning techniques have been used to develop a PSS as a Deep reinforcement learning-based method in [13], a neuro-adaptive predictive control in [14], a fuzzy-based controller in [15][16][17], damped Nyquist plot for the phase and gain optimization in [18] but all these algorithms may require intensive computations compared to simpler algorithms, especially for complex problems.…”

Control and capacity planning for energy storage systems to enhance the stability of renewable generation under weak grids

“…Related researches on using additional equipment to enhance the RPG stability have been published: Power system stabilizers can suppress the instability between interconnected power systems, but they are generally only effective for low-frequency oscillations [22,23]. An adaptive active damper for improving the stability of grid-connected inverters under the weak grid is proposed in [9].…”
