Abstract
In Egypt, the traditional power system operation relies on the concept of independent but coordinated functioning of multiple “control areas”. A control area is a portion of the system (lines, transformers, loads, and other equipments) under the supervision and control of a single operator (or under a single administrative structure). Control center operators maintain the system’s integrity, prevent outages and insure reliable operation, by following reliability rules. The rules are intended to balance supply and demand without creating overloads, congestion, or other similar problems. Every control area in the system is “responsible” for balancing its generation with its load. Whenever there is insufficient generation, the entire system ”slows down” (i.e., the frequency DROPs). Operations of a control area are based not only on maintaining a balance between supply and generation to control the frequency of the system but also on maintaining the bus voltages in acceptable limits. The concept of control areas in the American transmission gird has addressed by Fernando Alvarado and Shmuel Oren in Ref.
[1] It may be desirable to have more numerous and smaller control areas to avoid handling of large amounts of data, and complexity that might make the system difficult for operators to understand. More control areas, however, mean greater need for coordination among them. The West Delta Regional Control Center (WDRCC) is a control area that responsible to assure that degree of system reliability and security in the West Delta (WD) network, apart of the Egyptian network. Other six control centers such as the North Cairo Control Center (NCRCC) and Middle Delta Regional Control Center (MDRCC) follow similar objectives. The improvement of a control area operation leads directly to the overall gird improvement. The primary, traditional objective of power system operation is to maintain system integrity. This means that uncontrolled cascading outages must be prevented. Maintenance of system integrity is referred to as “security”.
