Abstract
The notion of the state of health is widely used in asset management. For instance, electric vehicle batteries are replaced after they lose ∼30% capacity, which means that their state of health is not good enough for reliable use in day-to-day travels, even though they still possess 70% capacity. Estimating the state of health of an asset is difficult, and for a power grid spanning thousands of kilometers and interconnecting millions of components, it is barely imaginable. We use familiar biomedical tests, such as blood tests, to grasp quantitative information about the health of a person, which is then interpreted by a doctor. A similar measurement-based approach is adopted in power grid operations. Electronic devices located in substations acquire and process current and voltage signals, breaker status, meteorological data, etc., which are sent to control rooms for digestion and interpretation by power system operators.
