  The dispatch of capacitors on a distribution feeder in daily system operation is investigated. The objective is to reach an optimal capacitor dispatching schedule, based on the forecast hourly loads for the next day, such that the total feeder loss in a day is minimised. The constraints that must be taken into account include the maximum allowable number of switching operations in a day for each capacitor, and the voltage limits on the feeder. An approach based on dynamic programming is presented to reach such an optimal schedule. To demonstrate the effectiveness of the proposed approach, the dispatch of capacitors on a distribution feeder within the service area of Taipei West District Office of Taiwan Power Company is investigated. It is concluded that a greater loss reduction can be achieved by the optimal capacitor dispatch than by the fixed-schedule dispatch.

  A computer algorithm designed for Monte Carlo production cost simulation is described. The design seeks to enhance the precision of production cost estimation at a reduced computation time compared with the existing approach. The algorithm has three major computer steps: (i) to formulate a state population according to the uptime/downtime of the generating unit, hence to simulate generation availability; (ii) to stratify this population by a mathematical rule and draw sample states out of each stratum; and (iii) to estimate the population mean of unit commitment production costs by the rank statistics of the sample. The stratification rule aims to remove any judgemental input and to render the stratification process entirely mechanistic. The estimator, given by rank statistics of the sample, can avoid identification of the regression model and thus save computation time. The algorithm has been evaluated and compared numerically with the existing approach. Hence, the effectiveness on precision improvement is demonstrated.

  The paper presents the application of a new impedance relaying principle to a Teed feeder. The relay design is immune from false tripping owing to power swings or prefault load conditions. This has been achieved by extracting and using prefault and superimposed components of relaying voltages and currents. Results are presented for earth faults on a Teed feeder configuration. Relay trip time is typically in the range 11 to 20 ms and is plotted as a surface against prefault power angle and fault point on wave angle.
Modelling multiple injection bus in power system state estimation

  State estimation which uses redundant real-time telemetry to estimate the system state is considered to be one of the essential parts of the modern energy management system. Owing to modelling restrictions in a multiple injection bus, many of the injection measurements at a bus, in certain circumstances, are not usable, and the estimated net injection cannot be correctly distributed among the individual injections. Two new methods are proposed to model the multiple injection bus. Test results indicate that the proposed methods cannot only utilise all available measurements but also provide a convenient way of estimating individual injections contributing to a bus.
Damping torsional oscillations using a SIMO static VAR controller

  Stabilising torsional oscillations using a single input multiple output (SIMO) static VAR controller is investigated. An eigenstructure assignment technique is applied to design it. The designed controller can be easily implemented by a multiple proportion integral (MPI) controller using medium pressure turbine speed, two low pressure turbine speeds, and generator shaft speed as the feedback signals. Eigenvalue analyses under a wide range of series capacitor compensations and loading conditions, time domain simulations under a pulsed torque disturbance, and fast Fourier transform (FFT) analyses for system behaviour are all performed to demonstrate the effectiveness of the proposed controller.
