Applicability of Low Frequency Transmission Technology in Offshore Wind Power Transmission Scene

Design of Low-Frequency AC Transmission System for Offshore Wind Farms

In recent years the amount of electricity produced from wind has grown rapidly. Offshore wind farm is currently seen as a promising solution to satisfy the growing demand for renewable energy source. The main reasons for the rapid development of offshore wind farms includes much better wind resources and smaller environmental impact. However, the current state of the offshore wind farms present...

Optimal Power Transmission of Offshore Wind Power Using a VSC-HVdc Interconnection

High-voltage dc transmission based on voltage-source converter (VSC-HVdc) is quickly increasing its power rating, and it can be the most appropriate link for the connection of offshore wind farms (OWFs) to the grid in many locations. This paper presents a steady-state operation model to calculate the optimal power transmission of an OWF connected to the grid through a VSC-HVdc link. The wind tu...

Transmission systems for offshore wind farms in the Netherlands

In this paper a detailed technical analysis is presented for connecting three different sizes of wind farms (100, 200 and 500 MW) considering three different transmission solutions: 150 kV AC, 400 kV AC and ±150 kV VSC-HVDC. After a brief overview of the features of the possible connection solutions, the related operational aspects have been evaluated. A comparative economical assessment is mad...

Simulation of Offshore Wind System with Three-Level Converters: HVDC Power Transmission in Cloud Scope

This paper is on a simulation for offshore wind systems in deep water under cloud scope. The system is equipped with a permanent magnet synchronous generator and a full-power three-level converter, converting the electric energy at variable frequency in one at constant frequency. The control strategies for the three-level are based on proportional integral controllers. The electric energy is in...
