“…In this paper, we abandon these models and use port-Hamiltonian systems [36] to model power systems from first principles. As already suggested in [31], a power system can be represented as the interconnection of individual port-Hamiltonian systems. There are several advantages of this approach.…”

“…These conditions show that as long as we have enough dissipation, there will be no loss of synchronization. In [31] the port Hamiltonian framework is also used to derive sufficient conditions for the stability of a single generator. The techniques used in [31] rely on certain integrability assumptions that require the stator winding resistance to be zero.…”

Abstract. During the normal operation of a power system all the voltages and currents are sinusoids with a frequency of 60 Hz in America and parts of Asia, or of 50Hz in the rest of the world. Forcing all the currents and voltages to be sinusoids with the right frequency is one of the most important problems in power systems. This problem is known as the transient stability problem in the power systems literature.The classical models used to study transient stability are based on several implicit assumptions that are violated when transients occur. One such assumption is the use of phasors to study transients. While phasors require sinusoidal waveforms to be well defined, there is no guarantee that waveforms will remain sinusoidal during transients. In this paper, we use energy-based models derived from first principles that are not subject to hard-to-justify classical assumptions. In addition to eliminate assumptions that are known not to hold during transient stages, we derive intuitive conditions ensuring the transient stability of power systems with lossy transmission lines. Furthermore, the conditions for transient stability are compositional in the sense that one infers transient stability of a large power system by checking simple conditions for individual generators.

“…However, the full-order model of the synchronous machine as derived in many power engineering books like [2], [6], [8] is difficult to analyze, see e.g. [5] for a port-Hamiltonian approach, especially when considering multi-machine networks [4], [9]. Moreover, it is not necessary to consider the full-order model when studying electromechanical dynamics [8].…”

Abstract-This paper investigates the problem of optimal frequency regulation of multi-machine power networks where each synchronous machine is described by a sixth order model. By analyzing the physical energy stored in the network and the generators, a port-Hamiltonian representation of the multimachine system is obtained. Moreover, it is shown that the openloop system is passive with respect to its steady states which implies that passive controllers can be used to control the multimachine network. As a special case, a distributed consensus based controller is designed that regulates the frequency and minimizes a global quadratic generation cost in the presence of a constant unknown demand. In addition, the proposed controller allows freedom in choosing any desired connected undirected weighted communication graph.
