Strategic Transmission Investment using Modular Static Synchronous Series Compensators

Duke Energy, a major US utility, describes the application of modular SSSCs to enable strategic transmission investment. Modular SSSCs mitigate risk by alleviating overloads that could occur due to deferred projects. Duke evaluates the use of modular SSSCs to defer a reconductor for several years and finds this solution is lower cost, smaller footprint and greater flexibility than alternate forms of power flow control.
