Switching procedures in multiple source systems and the Business Continuity Management: The flock logic of multi-set systems

The architecture of a mission critical power system has to guarantee service continuity and so has to be designed with multiple structures that allow the simultaneous operation of multiple sources. The architectural measures can be applied on the distribution levels, on total or partial redundancy introducing loop configuration and floating nodes. Opportunely organized, the Business Continuity Management (BCM) will project its program and take actions on the sources. Complete control of the system is necessary for all operating occurrences in an electrical power system, control based on a full understanding of system performance during such operations, particularly when they are complex. Complexity requires that the “safe sets” of operating procedures have to be identified out of all the probabilistic possibilities, selected and authorized adopting the Parise program. The paper deals with a sample case of a system with multiple sources applying the micro approach of the “flock” logic.
