The Voltage Source Converter based HVDC provides asynchronous interconnection between two AC systems. The use of VSC HVDC enables independent control of real and reactive power. The VSC based HVDC transmission system consists of two converter stations connected by a dc cable/line. This paper presents modelling and the design of controller for VSC HVDC. The various operating cases of VSC HVDC are considered...
In this paper, the power system stabilizer (PSS) and flexible ac transmission system devices (FACTS) interaction is investigated. The objective of this work is to study and design a controller capable of doing the task of damping in less economical control effort, and to globally link all controllers of national network in an optimal manner, towards smarter grids. This can be well done if a specific...
The present article deals with finding the best position of piezoelectric actuator for active vibration control of square plate with all-clamped edges using the genetic algorithm (GA) and developed optimization algorithm (DOA) base on controllability grammian. The controllability grammian is obtained using the modal force constants, the eigenvalues and eigenfunctions of all-clamped edges plate. The...
Wide-area controllers have been proposed to enhance the dynamic performance of large interconnected power systems. The time delay existing in the data communication may be a detriment to wide area control system stability. This paper analyzes the effect of time delay on the additional interarea damping control (AIADC) design of PSS. The AIADC is proposed for generators' excitation controllers and...
In this study, we proposed a genetic adaptive filter to removing power-line interference. In previous work, the proposed structure, which extracts the interference component from the input biomedical signal to be a reference signal of the adaptive filter to estimate power-line interference, is effective for removing interference. Since this adaptive filter with least-mean square algorithm is sensitive...
