An application of modular FACTS devices to relieve transmission constraints and accelerate wind farm connections and firm access

An application of modular FACTS devices to relieve transmission constraints and accelerate wind farm connections and firm access                                      

This paper explains how modular power flow control can be used to quickly create additional capacity in ways not previously deemed cost effective or possible. This technology can alleviate grid constraints that limit renewable generation on the transmission and distribution grids.

Comparative Performance of Smart Wires SmartValve with EHV Series Capacitor: Implications for Sub-Synchronous Resonance (SSR)

Comparative Performance of Smart Wires SmartValve with EHV Series Capacitor: Implications for Sub-Synchronous Resonance (SSR)                                  

EnerNex used the IEEE Second benchmark Model for SSR to compare the performance of the SmartValve with a conventional passive series capacitor. Simulations showed that active voltage injection from the SmartValve provides reactive compensation at line frequency like series capacitors. However, unlike series capacitors, the SmartValve does not inject voltage at frequencies other than the fundamental frequency, and hence does not create network conditions that could lead to SSR.
