Bruce Muschlitz served as the principal EnerNex investigator for to determine test strategies for a centralized utility remidial action scheme system. The analysis is contained in a written report and presentation to the Western Area Coordinating Council. This work is performed under sub-contract to SISCO (System Integration Services Company) for Southern California Edison.
Remedial Action System are developed by utilities to mitigate problem caused by extreme emergency situations. A simple example of a RAS system is a load shed load when multiple simultaneous line outages occur within a single transmission corridor during times of heavy load flows.
Most present RAS systems are distributed in the sense that a fixed set of input conditions causes a pre-determined response. A centralized RAS system could take a more global view of the system to optimize the RAS response. This optimization could result in the delay of building new generation facilities by a utility resulting in vast savings (hundred of millions of dollars).
The report covers the following areas:
