We determine the maximum amount of work extractable in finite time by a demon performing continuous measurements on a quadratic Hamiltonian system subjected to thermal fluctuations, in terms of the information extracted from the system. The maximum work demon is found to apply a high-gain continuous feedback involving a Kalman-Bucy estimate of the system state and operates in nonequilibrium. A ...

in trading electrical energy in deregulated power systems, violation of operation constraints such as transmission lines flow limits is possible. these conditions have been called “congestion”. one of the most important responsibility of independent system operator (iso) is congestion management in a manner that all the system equipments be operated in their nominal ranges. in this paper, usi...

Distributed generation takes center stage in today's rapidly changing energy landscape. Particularly, locally matching demand and generation in the form of microgrids is becoming a promising alternative to the central distribution paradigm. Infrastructure networks have long been a major focus of complex networks research with their spatial considerations. We present a systemic study of solar-po...

This paper is based on material presented at the IEEE 1995 Winter Power Meeting Panel Session on Challenges to OPF, sponsored by the IEEE Working Group on Operating Economics. The paper contains a brief summary of the session followed by summaries. INTRODUCTION J.A. Momob, Senior Member Howard University Washington, DC The increasing demand for an OPF tool for assessing state and recommended co...

The UPFC can provide simultaneous control of all basic power system parameters ( transmission voltage, impedance and phase angle). The controller can fulfill functions of reactive shunt compensation, series compensation and phase shifting meeting multiple control objectives. From a functional perspective, the objectives are met by applying a boosting transformer injected voltage and a exciting ...

The advantage of this method involves controlling the flow of current through all the connections – especially those used to measure the voltage. The measurement current flows through one set of connections, usually those that are farthest apart. If these connections are resistive (i.e., the connections are poor) there will be significant voltage drop across them. However, this voltage drop doe...

1. Destiny of Man This much will, I think, have been proven firmly enough one day: that the universe were the work of an Infinite Understanding, and were designed according to an excellent plan. Just as it now flows from the design into reality through the almighty influence of divine power, and all powers are active and act on each other, like strings of a thousandvoiced instrument sounding to...
