Studies indicate that reliable access to power is an important enabler for economic growth. To this end, modern energy management systems have seen a shift from reliance on time-consuming manual procedures, to highly automated management, with current energy provisioning systems being run as cyber-physical systems.

Power System Stabilizers Design for Interconnected Power Systems
IEEE Transactions on Power Systems, 2010This paper proposes a method of designing fixed parameter decentralized power system stabilizers (PSS) for interconnected multi-machine power systems. Conventional design technique using a single machine infinite bus approximation involves the frequency response estimation called the GEP(s) between the AVR input and the resultant electrical torque ...

Niklas Luhmann’s theory of power is based on two fundamental pillars. First, he analyzes power functionally as a symbolically generalized medium of communication, which endows his conception of power with a strong evolutionary foundation. Second, he claims that power is constitutively tied to negative sanctions.

Wind-Power Transforming Systems
Journal of Mathematical Sciences, 2001Summary: In this article, we give a brief account of theoretical and experimental investigations, as well as engineering designs, of different types of rotors (propeller-type rotors and Darrieus-type rotors). In numerical studies, we used the vortex lattice method.
