Comparative Performance of Smart Routers with EHV Series Capacitor: Implications for Sub-Synchronous Resonance
Smart Wires partnered with EnerNex to conduct simulations using the IEEE Second Benchmark Model to study the implications of SSR. EnerNex found that active voltage injection from the Power Router provides reactive compensation at line frequency like conventional series capacitors, but its actions do not extend to other frequencies.

Flexibility in Wind Power Interconnection Utilizing Scalable Power Flow Control
Adding power flow devices incrementally to constrained transmission lines provides benefits to both wind generation developers and transmission owners. Capital is only spent when it is necessary, generation developers can be charged incrementally, in-service dates can be accelerated and congestion can be relieved providing economic benefits.

Integration of Series FACTS Into Interconnect-scale Production Cost and Long-term Planning Tools
A commercial power system simulation and planning platform, called PLEXOS, has successfully been augmented to model series FACTS devices. The modeling capability has been demonstrated by planning a deployment of series FACTS devices in the Eastern Interconnection of the U.S., and the results indicate that the series FACTS can reduce the sum of production cost and capital cost for the study footprint.

A Case Study on the Use of D-FACTS Devices to Support Construction of New Transmission Facilities
Use of D-FACTS to control power flow over transmission lines to alleviate overloads when transmission facilities are removed to allow for construction of new transmission facilities is investigated. The economics of D-FACTS are evaluated by comparing with re-dispatching of available generating facilities in the system.

FACTS and D-FACTS: The Operational Flexibility Demanded by the Transmission Expansion Planning Task with Increasing RES
FACTS and D-FACTS benefit transmission expansion planning by providing an operational flexibility to different dispatch scenarios. This results in increasing asset utilization, maximizing existing transmission capacity, avoiding transmission line construction, and saving in transmission investment.

Deploying Power Flow Control to Improve the Flexibility of Utilities Subject to Rate Freezes and Other Regulatory Restrictions
Power flow control solutions can provide a shorter payback period for utilities. Such solutions can improve the flexibility of utilities subject to revenue decoupling, rate indexation, or rate freezes.
