A Decentralized Observer for Electrical Power Systems: Implementation and Experimental Validation

In the last few years the growing in complexity of the electrical power networks, mainly due to the increased use of electronic converters together with the requirements of higher level of reliability and security, pushed the development of new techniques for the state estimation of the power systems. In this paper, the author focus their attention on the implementation and experimental validation of a decentralized observer for the state estimation in an electric ship, whose power network is characterized by fast dynamics and by the presence of many electronic devices. The proposed solution implements a Decentralized Information Filter(DIF).
