The power quality analysis is an essential issue in the integration of distributed energy resources to grid. Recent standards regulate harmonics disturbances due increasing penetration intermittent sources interconnected with grid employing converters. This paper aims analyze wind turbine system based on a Squirrel Cage Induction Generator (SCIG) driven by Electromagnetic Frequency Regulator (E...

This paper presents an effective solution to overcome the problem caused by intermittent energy sources that are connected a balanced/unbalanced distribution system using superconducting magnetic storage (SMES) mitigating voltage and frequency fluctuations during wind gusts. The fuzzy logic control technique (FLC) is used with SMES improve frequency. A squirrel cage induction generator (SCIG) a...

Main flux saturation in induction machines plays an important role in a number of operating regimes and therefore has to be accounted for in the process of modelling. The current state space model of a saturated induction machine has gained substantial popularity recently as an excellent tool for transient and steady-state time domain analysis of induction motor drives when the main flux satura...

The market of small or micro electric energy generation units, often combined with local heat production, is becoming increasingly important. For these applications the classical asynchronous machine with cage rotor is an interesting generator. The grid-connected induction generator has some advantages over the synchronous generators: e.g. it is cheap, robust and maintenance-free. Since the ind...

Wind energy development is consumer and environment friendly, it requires shorter construction time compared to thermal, nuclear generation and is cost competitive. It becomes one of the most competitive sources of renewable energy. However, wind power has some disadvantages. For example, wind power is considered an intermittent power supply because wind does not blow 100% of the time. Besides,...

The paper describes a variable speed wind generation system where fuzzy logic principles are used for light load efficiency improvement and optimization. A squirrel cage induction generator feeds the power to an improved topology of matrix converter which pumps power to a utility grid or can supply to an autonomous system. The power factor at the interface with the grid is controlled by the mat...
