A novel technique used to design a simple version of an adaptive neuro-fuzzy controller (ANFC) is described in this paper. The structure of the proposed Adaptive Simplified Neuro-Fuzzy Controller (ASNFC) consists of reduced numbers of input membership functions (MFs) and consequence parameters (CPs). A Neuro Identifier (NI) is used to track the behaviour of the plant on-line and update the controller...
The elimination of low order harmonics in grid-connected renewable-energy inverter systems is desirable both from the point of view of grid health as well as efficient inverter operation. In this paper, one inverter (called reference inverter) employs pulse width modulation (PWM) with conventional selective harmonic elimination (SHE) to remove the 5th and 7th harmonics. By adjusting a delay in the...
A prospective application of applying an adaptive controller to a Static Var Compensator (SVC) to damp power system oscillations and enhance system stability is presented in this paper. The proposed adaptive controller consists of two parts, an adaptive neuro-identifier (ANI) and a Neuro-fuzzy Controller. The adaptive neuro-identifier is used in the control strategy to identify the plant dynamics...
An indirect adaptive controller for a Static Synchronous Compensator (STATCOM) is designed to damp oscillations and enhance the stability of power systems. A combined on-line identifier and a Pole-Shift (PS) feedback controller, as an adaptive power system stabilizer, is applied to a STATCOM device connected at the middle bus of a single machine infinite bus system. A Kalman Filter as a parameters...
This paper presents a prospective application of a Static VAr Compensator (SVC) in power systems, with particular emphasis on the use of an SVC with a supplementary adaptive controller to enhance system damping. The SVC adaptive controller consists of an on-line identified system model and a Pole-Shift (PS) feedback controller. Recursive Least Squares (RLS) identification algorithm and Kalman Filter...
In this paper, an adaptive controller for static synchronous compensator (STATCOM) is developed to damp oscillations and enhance the stability of power systems. The adaptive controller consists of an on-line identified system model and a pole-shift (PS) feedback controller. Adaptive linear element neuron (ADALINE) is used for on-line model identification to obtain a dynamic equivalent model of the...
