    The recent significant expansion of electric space heating calls for proper load management strategies for a northern climate. In this paper, a multimode system including heat pump technology with storage is developed. The variations of the room temperature setpoint are studied in relation to heating power and the setback pattern. A discrete-time solution to the problem of determining the optimal ...

    A coupling between similar modes of response in different parts of a power system has been observed in actual studies. A method of studying this coupling and of plotting the effect of parameter changes on the eigenvectors is presented. The method is illustrated with a sample system in which two modes that are normally separate from each other couple through the eigenvectors for certain values of t... View full abstract»

    This paper presents a new method for minimizing transmission line losses and improving voltage profile in a given system by adjusting control variables, i.e., tap position of transformers and reactive power injection of VAR sources. Transmission losses are considered as a function of voltage increments. The control variables and voltage increments are related by a modified Jacobian matrix. Linear ... View full abstract»

    A fixed Filter-Thyristor Controlled Reactor (FF-TCR) type of compensator is proposed to improve the power factor of a single phase thyristor-controlled inductive load and it is shown that this compensator gives better power factor improvement than the more generally used FC-TCR type of compensator. Analysis is carried out for the exact equivalent circuit of an FF-TCR compensator containing two fil... View full abstract»

    Time-scale decomposition is used to systematically produce improved reduced order models of interconnected multimachine power systems. The method is illustrated with two fundamental examples. The first shows that the I = YV interface equation used for studying multimachine electromechanical transients is a zero order representation of the fast network transients. As such, the time-scale theory can... View full abstract»

    This paper proposes a multiple bad data processing procedure for least-squares estimation of power system static state. The procedure is based on residual analysis by iterative deletion of suspected data and hypothesis test validation of the deleted good data. Comparision is made in algebraic, algorithmic and computational aspects with a recently proposed HTI method by Mili et al.[1]. The effectiv... View full abstract»

    A method of observability analysis for the state estimation in power systems is presented. The method is based on a symbolic reduction of the measurement Jacobian matrix without its actual computation. The algorithm is characterized as being extremely simple and fast. The results of the algorithm application in the Energy Management System (EMS) of a large electric utility are given. View full abstract»

    A field-proven dynamic programming formulation of the unit commitment problem is presented. This approach features the classification of generating units into related groups so as to minimize the number of unit combinations which must be tested without precluding the optimal path. Programming techniques are described which maximize efficiency. Considerations are discussed which determine when gene... View full abstract»

    A method is given for computing matrix reductions for power flow equivalents that is many times faster than presently used methods and produces extremely sparse equivalents. It is possible to embed the method in a power flow solution algorithm so that equivalencing can be performed automatically and transparently. The method is based on a property of sparse matrix factorization. When a matrix has ... View full abstract»
