A new strategy in wind speed prediction based on fuzzy logic and artificial neural networks was proposed. The new strategy for fuzzy logic not only provides significantly less rule base but also has increased estimated wind speed accuracy when compared to traditional one. Meanwhile, applying the proposed approach to artificial neural network leads to less(More)
Environmental, economical and technical benefits of photovoltaic (PV) systems make them to be used in many countries. The main characteristic of PV systems is the fluctuations of their output power. Hence, high penetration of PV systems into electric network could be detrimental to overall system performance. Furthermore, the fluctuations in the output(More)
This paper presents a vector control direct (FOC) of double fed induction generator intended to control the generated stator powers. This device is intended to be implemented in a variable-speed wind-energy conversion system connected to the grid. In order to control the active and reactive power exchanged between the machine stator and the grid, the rotor(More)
Two new configurations of static ground power unit based on 5L active neutral point clamped (ANPC) and novel modular 9L-ANPC converter are proposed. First, a new level shifted phase-shifted carrier pulse-width modulation (LS-PSC-PWM) switching method for the 5L-ANPC converter is defined. By utilizing the proposed method, total harmonic distortion of output(More)
