In the power system an unexpected increment of load demand has leads to the system to experience stressed condition. This phenomenon has led to voltage profile detract below the permissible limit. These Voltage profile in a stressed power system could be enhanced by having commensurate reactive power compensation. And this reactive power requirement is furnish through fast acting and self-commutated...
In this paper, rotor stability performance details of a grid connected type-1 wind turbine generator (WTG) system are presented. Small-signal and transient stability analyses are carried out including the models of the turbine-generator shaft system to show that the torsional modes natural to the shaft system gets excited only when the system exhibits rotor speed instability. This observation will...
The objective of this paper is to design a state feedback controller to damp out the inter-area oscillations in the power system network with limited wide area measurements. The conventional state feedback controller designed through LQR optimization requires all the state variables as input. However, the dynamics of a power system is governed by a large number of state variables. Therefore, it is,...
In deregulated electricity market available transfer capability (ATC) are of great importance, because many generators and distributors are available for sending and receiving the power from the transmission line. Hence in this paper flexible AC transmission system (FACTS) devices are incorporated in the power system to enhance the ATC of transmission line. The third generation FACTS device such as...
With rapid degeneration of conventional sources of energy, it is time to prepare our existing system to adapt to renewable power generation; a task full of challenges till today. The most promising approach that could provide a solution to this issue is the concept of smart grid. Smart grid, an advanced version of a present power system grid is expected to meet the challenges of future power demand...
