Doubly-fed generator smart microgrid

Is double fed induction generator suitable for grid-connected wind energy conversion system?

This paper presents the control strategies and performance analysis of doubly fed induction generator (DFIG) for grid-connected wind energy conversion system (WECS). The wind power produces environmentally sustainable electricity and helps to meet national energy demand as the amounts of non-renewable resources are declining.

Can a cascaded doubly fed induction generator (cdfig) manage a wind energy conversion system?

Author to whom correspondence should be addressed. This paper introduces a robust system designed to effectively manage and enhance the electrical output of a Wind Energy Conversion System (WECS) using a Cascaded Doubly Fed Induction Generator (CDFIG) connected to a power grid.

What is a DC hybrid microgrid?

In this paper we will deal with a DC hybrid microgrid combining both Fuel Cell (FC) and Doubly Fed Induction Generator (DFIG) based Wind Turbine (WT) technologies. We aim to control active and reactive powers injected into the grid and to study the system’s response to variant fuel inputs.

What is a doubly-fed induction generator?

Doubly-fed induction generators (DFIG) are the most widely used types of generators in wind energy conversion systems. This topology can offset its output power to stabilize fluctuations by a factor of typically up to ± 30%. However, this device is still small considering the range of variation in practice of the wind speed.

Why is a doubly fed induction generator a problem?

Due to the synchronous nature of this type of generator, problems may arise at start-up, making it difficult to achieve steady voltage. The doubly fed induction generator has strong control over producing reactive power, which may be sent to the stator via a grid-side converter.

Are microgrids a solution to distributed electricity production?

Amongst others, Microgrids (MGs) might be exploited as a solution to respond to these concerns and to optimise the energy of the available sources; We are speaking here on distributed electricity productions.
