    The paper proposes an application of evolutionary programming (EP) to power system reactive power planning (RPP). RPP is a nonsmooth and nondifferentiable optimisation problem for a multiobjective function. Several techniques to make EP practicable have been developed. The proposed approach is demonstrated with the IEEE 30-bus power system. The comprehensive simulation results show that EP is a su... View full abstract»

  • Application of the controllable series compensator in damping power system oscillations

    In the paper, the application of the controllable series compensator (CSC) in damping power system oscillations is investigated on the basis of the Phillips-Heffron model, which is established for a general n-machine power system. The capability of the CSC damping control to provide damping to the power system is analysed in terms of its damping torque contribution both for single-machine infinite... View full abstract»

  • Applications of customer outage costs in system planning, design and operation

    Although the basic function of an electric utility company is to supply power economically and at acceptable levels of continuity and quality, the emphasis placed on these aspects during planning, design and operation depends on the level of power system development. Further development of developed power networks is dominated by technological changes and concern for strict economic operation, qua... View full abstract»

  • Spinning reserve allocation using response health analysis

    An approach to evaluate the degree of system well-being in the responding capability of a generation system is presented. The overall well being of a generation system in terms of its responding capability is identified as being healthy, marginal and at risk. A risk criterion, designated as the `generating system response state risk' (GSRSR), is used to determine the generating unit loading schedu... View full abstract»

  • Scheduling short-term hydrothermal generation using evolutionary programming techniques

    The authors present a novel evolutionary programming (EP) based algorithm for the short-term hydrothermal scheduling problem. To more realistically represent the relationship between the generation and amount of water discharge for hydroaggregates, the generation models of the hydroelectric power plants as well as thermal power plants are often expressed as nonlinear and nonsmooth curves with proh...

  • Tracing the flow of electricity

    Continuing trends towards the deregulation and unbundling of power transmission services has resulted in the need to assess what impact a particular generator or load has on the power system. A new method of tracing the flow of electricity in meshed electrical networks is proposed which may be applied to both real and reactive power flows. The method allows the assessment of how much of the real a... View full abstract»

  • Combined active and reactive dispatch with multiple objectives using an analytic hierarchical process

    Publication Year: 1996, Page(s):344 - 352
    Cited by:  Papers (24)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (812 KB)

    A fully coupled active and reactive dispatch using linear programming and an analytic hierarchical process is developed. The purpose of combined active and reactive dispatch (CARD) is to achieve the overall objective of minimum generation cost and to improve the distribution of reactive power and voltage, subject to constraints which ensure system security. Security is defined as the maintenance o... View full abstract»

  • Three-phase optimal harmonic power flow

    Publication Year: 1996, Page(s):321 - 328
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (732 KB)

    A new three-phase optimal-harmonic-power-flow (TOHPF) method is proposed. It is designed to minimise the three-phase power losses and the total three-phase harmonic voltage distortion while satisfying the three-phase-power-flow equations, three-phase harmonic-power-flow equations, three-phase security constraints, and the three-phase harmonic standard etc. A two-level algorithm is used to solve th...

  • Capability of the static VAr compensator in damping power system oscillations

    The capability of the static VAr compensator (SVC) in damping power system oscillations is investigated on the basis of a Phillips-Heffron model of single-machine infinite-bus power systems. Analysis shows that the ability of the SVC to provide positive damping torque to power systems is influenced not only by the load conditions, as has been found previously, but also by the type (or parameters) ...

    The paper presents a system-wide continuous harmonic state estimator of three-phase asymmetric power systems, with development of its reduced mathematical models and algorithm, as well as its application to a New Zealand test system. The complete harmonic information throughout the power system, including location and even type of harmonic source, is estimated from a few synchronised, partial and ... View full abstract»
