Gorilla Troops Optimization (GTO) technique and Fractional Order Proportional-Integral-Derivative (FOPID) controller are used in this paper to increase the performance of photovoltaic system under critical disturbances shading situations. If solar irradiation is uniform, conventional MPPT techniques have been monitor maximum power point (MPP). They failed track true MPP within dynamic climatic ...

Abstract In this work, chaos game optimization (CGO), a robust approach, is employed for efficient design of novel cascade controller four test systems with interconnected power (IPSs) to tackle load–frequency control (LFC) difficulties. The CGO method based on theory principles, in which the structure fractals seen via chaotic principle and fractals’ self-similarity characteristics are conside...

The wind power generation has become more important nowadays to meet the increase in demand. DFIG based is recent and used many countries due its better controllability. controllers like Proportional Integral (PI) are for stabilization of waveforms supply system. change produces oscillation damping days. effect varying input generate using turbine resulting instability system because control do...

Microgrid control in isolated mode is a highly important subject area. In the present paper, a new method is used for controlling the isolated microgrids. This method was used based on the classification of the microgrids into two groups, namely fast-dynamic (battery and flywheel) and slow-dynamic (diesel generator, electrolyzer, fuel cell). For the microgrid components with fast dynamics, a se...

Having continuous decrease in inertia and being sensitive to load/generation variation are considered crucial challenging problems for modern power grids. The main cause of these is the increased penetration capacities renewables. An unbalanced load with generation largely affects grids’ frequency voltage profiles. Load control (LFC) mechanisms extensively presented solve problems. In literatur...

This paper investigates the performance achievable with a fractional-order PID regulator controlling Depth of Hypnosis (measured via Bispectral Index Scale) through administration propofol during maintenance phase total intravenous anesthesia. In particular, two different methodologies were applied to tune controller: in first case, genetic algorithms (GAs) used minimize integrated absolute err...
