Line flow calculation plays a critically important role to guarantee the stable operation of power system in economic dispatch (ED) problems with line constraints. This paper presents a line flow granular computing approach for power flow calculation to assist the investigation on ED with line constraints, where the hierarchy method is adopted to divide the power network into multiple layers to reduce...
Granular computing, as a new and rapidly growing paradigm of information processing, has attracted many researchers and practitioners. The large power grid could be decomposed into particles with different granularity according to granular computing method. Based on this, a hierarchical quotient space model could be built, so it would be convenient to choose the proper granule in the quotient space...
