Active Use of DFIG-Based Variable-Speed Wind-Turbine for Voltage Regulation at a Remote Location

Renewable energy sources are presently exempted from control functions. This, in turn, simplifies the requirements for the renewable energy source interconnection as well as the project developer, allowing connection to the system without having to take part in the overall stabilization effort.

Description
Summary:Renewable energy sources are presently exempted from control functions. This, in turn, simplifies the requirements for the renewable energy source interconnection as well as the project developer, allowing connection to the system without having to take part in the overall stabilization effort. Thus, in order to maintain the power generation and consumption balance, necessary for stable functioning of the power system, the traditional power plants always exert necessary control actions. However, the present practice requires the independent power producers and/or generators who want to connect to the grid to meet the so-called connection requirements of the local electric utility (the grid company). Therefore, this paper proposes an innovative reactive power control scheme for voltage regulation at a remote location that manipulates dynamically the reactive power from the voltage source converter (VSC) with taking into account its operating state and limits.
