DTC-SVPWM of an Energy Storage Flywheel Associated with a Wind Turbine Based on the DFIM

Abstract

In this article we will control the energy storage inertial noted inertial energy storage system to partner with a wind energy conversion system that aims to improve the power quality transit network. Inertial storage is considered a flywheel coupled to an induction motor and controlled by a voltage inverter type power converter. First step, a model of inertial energy storage system (flywheel + asynchronous machine) is presented, then two control methods are proposed: the direct torque control (DTC and DTCconventional SVPWM) (space vector pulse with modulation). The two control methods give similar performance, but the DTC-SVPWM requires less computation time. The two regulators and the proportional integrator SVPWM technique were used to determine the switching frequency. Using direct control with vector modulation strategy has enabled the inertial energy storage system of demonstrating good continuation even under rather severe operating conditions, and the torque ripples are significantly reduced compared to the case of conventional DTC. Then we come to the presentation of simulation results obtained.

Reduction of Power Production Costs in a Wind Power Plant–Flywheel Energy Storage System Arrangement

“…Such issues coincide with the interests of the authors of the paper, as exemplified by the paper [14]. The construction and selection of parameters of regulators and energy storage system management systems is a frequent issue in the scope of cooperation between WPP-FESS [16][17][18][19][20]. Their main objective is to reduce the adverse characteristics of wind energy, especially stochastic and dynamic changes in wind speed.…”

“…The value of electricity A WPP generated by the wind power plant consisting of N WT identical wind turbines over a period of one year can be determined on the basis of the measured wind speed variations and the power curve of the turbine P 1WT (v w ). Using dependence (2), the energy generated during year y is determined from the dependence: (16) where: N-number of wind speed measurement samples per year y.…”
