    This paper discusses the state of the art in short-term load forecasting (STLF), that is, the prediction of the system load over an interval ranging from one hour to one week. The paper reviews the important role of STLF in the on-line scheduling and security functions of an energy management system (EMS). It then discusses the nature of the load and the different factors influencing its behavior.... View full abstract»

    The operations scheduling problem in electric power systems is to determine which generating units should be on-line and available for generation at each hour and the associated nominal generation or dispatch. This paper describes the scope of the operations scheduling problem, presents mathematical formulations to the problem, and surveys recent advances in optimization-based solution methods. It...

    Within an Energy Management System, the Generation Scheduling and Control function controls the electrical power output of generators so as to supply the continuously changing customer power demand in an economical manner. This function is largely provided by an Automatic Generation Control (AGC) program operating within the control center computer. Power system dispatchers also play an important ...

    The use of large digital computers in control centers has made it possible to track the changing conditions in the power system with a mathematical model in the computer. This real-time model can be used to assess the security of the present system as well as to check out possible control strategies. In this paper the various steps in constructing the model from the real-time measurements are desc... View full abstract»

    An operationally "secure" power system is one with low probability of blackout or equipment damage. The power system control processes needed to maintain a designated security level at minimum operating cost are extremely complicated. They increasingly depend upon on-line computer security analysis and optimization. This on-line technology is still relatively new, with enormous further potential. ... View full abstract»

    The acquisition of data, the processing of those data for use by the operator, and operator control of remote devices are the fundamental building blocks upon which all modern utility control systems are based. The systems to accomplish these functions are known as Supervisory Control and Data Acquisition (SCADA) systems. This paper provides an overview of the functions of SCADA and the fundamenta...

    The current technology of Energy Management Systems computer configurations is reviewed in this paper. Computer system architectures have changed significantly over the years because of changing requirements from utilities and changes in the available hardware and software technology. The paper shows how configurations have evolved and in today's systems there is much commonality in approach. Fina... View full abstract»

    Electric utilities require reliable data communications for power system control, operations, and maintenance. Utilities are among the largest users of data and, it has been said, the largest users of real-time data. In recent years, there has been an effort to apply the emerging technology of data communication networking to utility applications for real-time data exchange. Emphasis in this paper...

    Power system operators often reach a cognitive barrier when information arrives too fast during a power system emergency. At such times it becomes difficult to reach a correct diagnosis of the problem or to formulate the correct decision when actions must be taken. Artificial Intelligence gives designers of Energy Management Systems a way to solve many of the diagnosis and decision problems so as ... View full abstract»

    We have analyzed radar polarimeter signals from a set of trihedral corner reflectors located in the Goldstone Dry Lake in Cafifornia, and observed three types of scattering behavior: i) Bragg-like slightly rough surface scattering that represents the background signal from the dry lake, ii) trihedral corner reflector scattering that returns the incident polarization, and iii) two-bounce corner ref...

    Fabrication of near state-of-the-art (P0= 110 mW, η = 4.85 percent p+-n-n+D band (f = 124 GHz) Si IMPATT diode on a wafer with ramped n-n+interface is described. Introduction of a critical annealing step, prior to p+diffusion, in the fabrication sequence of the diode has been found to yield the above results. Possible reasons for power an...

  • Simple methods for the calculation of root of a reconfigurable binary tree structure

    Publication Year: 1987, Page(s):1690 - 1692
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (239 KB)

    In a reconfigurable binary tree structure controlled by a shift register with variable bias (SRVB), the root of a particular configuration is a function of the bias applied to the structure. This letter proves two new theorems for the derivation of formulas for the calculation of the root for a given bias. These are simpler than those obtained by Kartashev and Kartashev [1]. Consequently, both the... View full abstract»

    A new, fast method for angle-of-arrival estimation comparable in performance to modern eigen-decomposition based techniques is described. This method is well-suited to systolic array implementations. An adjunct to the method is an estimator for determining the most likely number of incident signal components. View full abstract»

    We described spiking filtering of all-pass filter impulse responses. We established a rule about the optimum delay and obtained the optimum spiking filter. We also showed that this result can be successfully applied to additional filtering to increase the resolution even further. View full abstract»
