3. Network Configuration

This chapter presents the rudiments of the schemes devoted to processing the network statuses of circuit breakers/switches, which is necessary for describing the grid connectivity and transforming the bus-section/circuit breaker representation into the bus-branch model required for power system state estimation (SE) and other network analysis functions. Substation bus configurations (radial, two buses, breaker-and-a-half, and ring bus) are addressed. Also, the problem of detecting/identifying network configuration errors—categorized as reported network changes that did not occur (type A) or appeared network changes are unreported (type B)—is addressed here. These errors involve the inclusion/exclusion of network elements, depending on whether they relate to false closed/open status information. The influence of network configuration errors in the SE process is indicated. Advanced topics, a list of problems, and references close the chapter.
