Abstract: Considering the bid prices of power plants for access to power networks, this paper advances a method of superintending and counting the real-time power loss by introducing the conception of cost-flow. It replaces the active loss with active cost loss, which improves the precision and comparability of power loss control as well as the benefits of power system, and provides a useful criterion for the real-time optimization of power dispatch.
Key words: real-time; power loss; cost flow; monitoring
