| | PDF (688 KB)

The paper presents an adaptive neural network approach to the estimation of the harmonic components of a power system. The neural estimator is based on the use of an adaptive perceptron comprising a linear adaptive neuron called Adaline. The learning parameters in the proposed algorithm are adjusted to force the error between the actual and desired outputs to satisfy a stable difference error equa... View full abstract»

| | PDF (844 KB)

In the UK, the concept of reliability worth has been considered a factor in justifying power system reliability investment since the late 1970s. Two specific considerations which have been developed are the implied cost per kWh saved', and the value of lost load'. These considerations apply historical methods for the assessment of reliability worth which rely on placing a worth value to the `ene... View full abstract»

A novel approach for multiobjective generation scheduling is presented. The work reported employs a simple heuristics-guided evolutionary algorithm to generate solutions to this nonlinear constrained optimisation problem where the objectives are mutually conflicting and equally important. The algorithm produces a cost-emission frontier of pareto-optimal solutions, any of which can be selected base... View full abstract»

The insulation of the 400 kV transmission lines located in the Northeast part of Mexico (Monterrey) have experienced flashover problems due to pollution accumulation. Several actions have been taken to increase their reliability (washing, use of RTV coatings, insulators with longer leakage distance, etc.). In order to help the maintenance work on these lines, a system for the measurement of leakag... View full abstract»

The effectiveness of three types of FACTS-based power system stabilisers are compared with the PSS in terms of their modal controllability to the oscillation modes in multimachine power systems. The comparison is focused on two aspects of the damping effect of the stabilisers; first the robustness of the stabilisers to the variations of system parameters and operating conditions and secondly, the ...

The work explores the use of a genetic algorithm for the solution of an economic dispatch problem in power systems where some of the units have prohibited operating zones. Genetic algorithms have a capability to provide global optimal solutions in problem domains where a complete traversion of the whole search space is computationally infeasible. Two different implementations of the genetic algori... View full abstract»

During the last decade, the power system voltage collapse phenomenon has attracted more and more attention. The phenomenon has been proved to be the reactive power shortage problem. Appropriate reactive power planning can enhance system security and may also reduce system losses. Weak bus oriented reactive power planning for power system security is presented. The algorithm identifies weak buses a... View full abstract»

| | PDF (332 KB)

Electric railway traction power systems are usually modelled as branched ladder electrical circuits with many variable power loads changing in time and moving in space. Effective simulation of these traction power networks depends both on understanding the nature of the system and hence accurate modelling, and on selecting efficient algorithms for the iterative part of the solution. Simulation mod... View full abstract»

Controllable series compensation (CSC) is one of the main flexible AC transmission systems (FACTS) devices, which have the ability to improve the utilisation of existing transmission systems. However, the implementation of this technology changes the apparent line impedance, which is controlled by the firing angle of thyristors, and is accentuated by other factors. This poses problems for conventi... View full abstract»

A set of power element models are established in an α-β-0 reference frame with different degrees of coupling. For untransposed, asymmetrical three-phase transmission lines, the so-called decoupling compensation models can be used. For Y/delta-connected transformers and fault/manipulation interfaces, different sets of low-order algebraic equations are introduced. Thus, by incorporating t... View full abstract»
