The Health Index Methodology of Integrated Energy System

The current research on health index for power grid in integrated energy system is mainly focused on single equipment components, which includes the high voltage equipment with high monomer value and a large number of low voltage power distribution equipment, rather than the power system network. Furthermore, those research includes qualitative evaluation and simple calculation model. This paper has carried out the research of distribution network health index theory and its application. The concept and research status of the health index of equipment were summarized. The definition, classification method and model of distribution network health index were proposed.
