Comparison of Wind Energy Integration into a 110kV and a 380kV Transmission System - Impact on Power Quality of MV and LV Networks

Abstract

the amount of electrical energy produced by wind farms is constantly increasing. Nowadays detailed analyses considering the impact of wind energy integration on the transmission system are required. Therefore several wind impact studies have been carried out. The conclusions of these studies are related to different aspects of wind power, such as it's fluctuating nature, distributed location of wind farms, generator technologies, generator control etc. The goal of this study is to compare the power quality behavior of the MV and LV network in case of integration of different amounts of wind energy at different locations of the 110 kV and 380 kV transmission systems. Keywords-component; aggregated wind farms, 110 kV and 380 kV transmission system with MV and LV subsystems, power quality analysis, wind energy integration

Distributed Energy Resources (DER) Systems Integration into MV and LV Networks - Impact on Power Quality of the System

“…In order to present a general overview of the network a block design of the whole power system model has been created (Fig 1). This test network has been used for different studies in power quality [4], [5]. It has been extended for this study by integrating DER units.…”

“…The main components of the DFIG are: induction generator model, PWM converters and pitch control. Furthermore, it is assumed that the wind-farms are equipped with low-voltage ride-through capability and reactive current support according to the connection standards[5].…”
