Distributed Intelligent Power Networks – A New Concept for Improving T&D System Utilization and Performance

This paper presents a new approach for realizing a smart, fault tolerant, controllable and asset efficient power grid through the use of massively-dispersed mass-manufactured communicationsenabled sensor, power-converter and actuator networks. One example is ‘Smart Wires’, implemented using many modules of a Distributed Static Series Compensator (DSSC) device that can be clamped on to existing power lines, and can be operated so as to control the impedance of the conductor – thus controlling power flow. This approach promises important system-wide benefits including – increased line and system capacity; increased reliability; improved asset utilization; improved operation under contingencies; reduced environmental impact; incremental deployment; and rapid implementation.
