Wind energy integration into 380 kV system-impact on power quality of MV and LV networks

Abstract

The amount of electrical energy produced by wind mills is constantly increasing. Nowadays detailed analyses considering the impact of wind energy integration on the transmission system are required. The goal of this study is to examine the power quality behavior of the network in case of integration of different amounts of wind energy at different locations of the 380 kV transmission system. In order to analyse the impact of wind energy integration on the network's power quality, a 380 kV transmission system with MV, and LV subsystems is modeled, integrated wind farms are used and power quality analyses are performed.

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

“…In this paper Load Block A is analyzed [2,3]. Consequently the Load Blocks A of the both systems are explained.…”

“…Consequently the impact of these power sources not only to the transmission system, but also to the medium and low voltage subsystems, has to be analyzed. Therefore wind energy integration into a 110kV and a 380kV transmission system studies have been carry out [2,3]. The conclusions of these two studies have been compared and analyzed.…”

“…It was assumed for the model formation of the wind farms that 125 MVA aggregated wind farm models have been used [2,3].…”

Influences of Wind Energy Integration into the Distribution Network

“…These generators can also support the system during voltage sags, though this converter-based system injects harmonic distortion into the systems. Power quality behaviours, in particular voltage sags and harmonics injection into the network, were investigated in a study [26] on integrating wind energy into low voltage and medium voltage networks. Results showed low injection of voltage sags for all the three case study scenarios.…”

Lab Model for a Low Power Wind Turbine System

“…Most used generators for wind turbine systems are permanent magnet synchronous generators [9]- [11] because the excitation field does not require a DC voltage source. The literature in the field of wind energy is very rich and it is a special chapter in electrical engineering [12]- [15].…”
