WebSep 15, 2012 · This paper presents a new coherency identification method for dynamic reduction of a power system. To achieve dynamic reduction, coherency-based equivalence techniques divide generators into groups according to coherency, and then aggregate them. In order to minimize the changes in the dynamic response of the reduced equivalent … In computers it is typical to define rules relative to data transfers for optimizing the overall system considerations. One such consideration is to define coherency granules (CG) that relate to units of data that are stored in memory. These units generally have a close relationship to caches that may be used in the system. The Coherency Granule size typically corresponds to the cache line size in a computer system.
