Equivalent Modeling of Dfig-Based Wind Farms for Sub-Synchronous Resonance Analysis

open access: yesEnergies, 2020
The order of the detailed model of doubly-fed induction generator (DFIG) wind farms are too high and the simulation is difficult. Most of the existing research has used a single-machine equivalent model and clustering aggregation model for equivalence ...

Simulation of a Power Regulation System for Steam Power Plants

open access: yesEnergy Procedia, 2014
AbstractRenewable energy sources, presently constituting about 23% of the total Italian power production, are featured by very discontinuous supply during the day that, to avoid grid malfunctions, must be compensated by fossil fuelled power plants. The latter must hence be able to rapidly control power supply.This paper proposes a power regulation ...
