This study analyses yearly and seasonal wind speed data recorded over eight years using Weibull distribution function the direct power control application of a chain. The potential evaluation was carried out based on empirical model. Results show that, during warm months is uniform, constant stable. In addition, it has been found that use strategy necessary for extracting optimum power. For thi...

Picosecond laser induced fluorescence measurements provide for the first time the direct meanrrement of the intramolccular and intermolecular energy decay dynamics of singlet diphenylcarbene (’ DPC) in the presence of reactive molecules. As exemplified by the reaction of ’ DPC with alcohols it is found that reactive molecules provide ’ DPC witi not only a chemical decay channel but also an intr...

In this paper present a sensorless maximum wind power extraction for variable speed constant frequency (VSCF) wind power generation systems with a doubly-fed induction generators (DFIG), to ensure stability and to impose the ideal feedback control solution despite of model uncertainties , using the principles of an active and reactive power controller (DPC) a robust sliding mode power control h...

The Vienna-type rectifier is broadly employed in various implementations thanks to realizable three-level operation, simple structure and controllable DC-link voltage. This paper proposes an adaptive proportional integral (PI) with anti-windup based direct power control (DPC) improve dynamic response during load change, voltage step change start up reduce current tracking errors. An PI utilized...

<span lang="EN-US">This paper proposes a new technique of maximum power point tracking (MPPT) for photovoltaic (PV) system connected to three phase grids under partial shading condition (PSC), based on combined perturb and observe (P&O) with scanning algorithm. This algorithm main advantages are the high-speed compared existing algorithms, high accuracy simplicity which makes it i...

A multivariable control strategy in a dq reference frame for grid-connected voltage source converters (VSCs) without using phase-locked loop (PLL) is presented this paper. First, common VSC controls such as vector current (VCC) and grid modulated direct power (GVM-DPC) are analyzed their main drawbacks identified. Then, the presented, including implementation of saturation anti-windup mechanism...

Two levels back-to-back converter is used to ensure energy transfer between DFIG rotor grid. The operate efficiently, maximum power point tracking (MPPT) algorithm implemented. Then, direct (DPC) strategy has been c...

This paper presents a low power impulse-radio ultra-wideband (IR-UWB) receiver based on a reconfigurable, high speed analog correlator called distributed pulse correlator (DPC). The DPC incorporates built-in local template pulse generation, and hence significantly reduces the power consumption and circuit complexity of the analog correlation receiver. A chip prototype of the IR-UWB receiver was...
