Power engineering is the sub-discipline of electrical engineering that deals with power systems, specifically electric power transmission and distribution, power conversion, and electromechanical devices. Out of necessity, power engineers also rely heavily on the theory of control systems.

History

Power engineering is arguably the earliest field to arise in electrical engineering. Early problems solved by engineers include efficient and safe distribution of electric power.
