Generalised neuron-based adaptive power system stabiliser - Generation, Transmission and Distribution, IEE Proceedings-

چکیده
Artificial neural networks (ANNs) can be used as intelligent controllers to control nonlinear, dynamic systems through learning, which can easily accommodate the nonlinearities and time dependencies. However, they require long training time and large numbers of neurons to deal with complex problems. To overcome these drawbacks, a generalised neuron (GN) has been developed that requires much smaller training data and shorter training time. Taking benefit of these characteristics of the GN, a new generalised neuron-based adaptive power system stabiliser (GNPSS) is proposed. The GNPSS consists of a GN as an identifier, which tracks the dynamics of the plant, and a GN as a controller to damp low-frequency oscillations. Results show that the proposed adaptive GNPSS can provide a consistently good dynamic performance of the system over a wide range of operating conditions.

A robust, adaptive control scheme is presented which stabilises a nonlinear model of a power system to disturbances anywhere in the power system. The control is local, in the sense that the control of each machine depends only on information available at the machine. Simulation results are presented which show that the control is very effective against instabilities of current importance such a...

Abstract: Optimization of DG and capacitors is a nonlinear objective optimization problem with equal and unequal constraints, and the efficiency of meta-heuristic methods for solving optimization problems has been proven to any degree of complex it. As the population grows and then electricity consumption increases, the need for generation increases, which further reduces voltage, increases los...

A method and a detailed adaptive algorithm for wide-range frequency change measurement is presented. The method is based on a two-stage operating principle in which the results of a coarse frequency measurement are used for both orthogonal filter adjustment and modifications to the basic algorithm that is applied to fine frequency estimation. The adaptive features ensure good selectivity of the...
