Balancing of instantaneous power flow in local area power network with Tellegen's theorem

摘要

It is important to manage precise power flows in closed small power networks for their reliable operations. This paper describes a method for managing the instantaneous power flows in a local area power network. In order to provide instantaneous power to a load through a power bus without disturbing the other modules, we adaptively adjust the power flow and keep the balance of the instantaneous power. As a tool of the balancing, we use power flows based on Tellegen's theorem and Kirchhoff's voltage law to determine the network states uniquely.
