Genetic algorithm (GA) has been used in this study for a new approach of suboptimal model reduction in the Nyquist plane and optimal time domain tuning of proportional-integral-derivative (PID) and fractional-order (FO) PI(λ)D(μ) controllers. Simulation studies show that the new Nyquist-based model reduction technique outperforms the conventional H(2)-norm-based reduced parameter modeling techn...

Abstract The constant changes in the load power lead permanently to a mismatch between generation and consumption. So, system frequency due imbalance deviates from nominal value. Consequently, control loop should be implemented stabilize whenever change occurs. This paper presents new super‐twisting sliding mode methodology for obtaining an optimal performance multi‐pool system. three‐pool devi...

Power electronics-based converters have been widely used in several applications, specifically electric propulsion systems. Ongoing advancements led to high-gain Quadratic Boost Converters (QBC) which control Permanent Magnet Synchronous Motor (PMSM) drive. In this work, a novel scheme is employed, particularly three-phase inverter between QBC and PMSM operated by dual-mode controller strategy....

Connection between electric power networks is essential to cover any deficit in the generation of from them. The exchange powers plants during load disturbance should not be violated beyond their specified values. This can achieved by installing frequency control (LFC); therefore, this paper proposes a new metaheuristic-based approach using skill optimization algorithm (SOA) design fractional-o...

Frequency, tie-line power, and the terminal voltages of synchronized generators must all be kept within prescribed limits to ensure stability an interconnected power grid through combined automatic generation control (AGC) voltage regulator (AVR) loops. Thermal plants, electric vehicles, renewable energy sources—including solar wind, geothermal, thermal plants—form two-area integrated system in...
