Control Structure for Single-Phase Stand-Alone Wind-Based Energy Sources

Abstract

Abstract-This paper is analyzing the operation of a standalone wind turbine system with variable speed Permanent Magnet Synchronous Generator (PMSG) and a system for storing energy during wind speed and load variations. Energy storage devices are required for power balance and power quality in stand alone wind energy systems. Initially, the holistic model of the entire system is achieved, including the PMSG, the boost converter and the storage system. The power absorbed by the connected loads can be effectively delivered and supplied by the proposed wind turbine and energy storage systems, subject to an appropriate control method. The main purpose is to supply 230 V/50 Hz domestic appliances through a single-phase inverter. The simulation results, validated by experimental testing, show a good prediction of the electrical parameter waveforms. The control system is implemented on a dSPACE DS1103 real-time board. Furthermore, the results confirm the stability of the supply.

Real-time testing of energy storage systems in renewable energy applications

“…This paper is focused on battery energy storage, specifically on valve regulated lead acid (VRLA) absorbed glass mat (AGM) batteries. Lead acid batteries offer low price, high unit-voltage, stable performance and a wide range of operating temperature [37]. In the actual BESS, the battery bank will consist of series-and parallel-combinations of a chosen battery.…”

“…Mutual inductance between two sets of stator [2][3][4][5]. Higher efficiency due to direct drive operation and high power density make them very attractive for extraction of wind and wave energy.…”

Integrated Controller for Elimination of Harmonics in PMSG Based WECS Feeding Non Linear Load

“…In [11] studied the injection of negative sequence current for reducing the unbalanced voltage at the point of PCC. The rotor currents are decoupled in to direct component and quadrature component for regulating active and reactive power using PI Controllers [12][13]. In [14], studied the contribution of SVC with Artificial Neuro-Fuzzy Interference system (ANFIS) is used to overcome the disturbance occurred during various operating conditions.…”
