Transfer capacity plays a vital role in both planning and operation of power system with respect to system security. The purpose of transfer capacity computation is to determine the amount of lost generation which can be replaced by system reserves and the limiting constraints in each circumstance. This paper presents a software solution of total transfer capacity (TTC) calculator embedded in energy...
This paper explores the relationship between system stability conditional probability and the sliding mode control for second order continuous Markovian jump systems. By using the stochastic process theory, multi-step state transition conditional probability function is proposed for the continuous time discrete state Markovian process. A sliding mode control scheme is utilized to stabilize the continuous...
The integrity of large-scale interconnected power grids may break down under system disturbances. The postdisturbance system may even turn out to cause a major blackout. To mitigate the undesired impacts of system disturbances, special protection systems (SPSs), also known as remedial action schemes (RASs), are widely used in modern power grids to safeguard their integrity.
Increase in complexity of electric power network operations due to several factors such as changes in market conditions, increase in imports / exports and also due to growth in load, electric power networks have become more stressed in their operation. This has provided opportunity for engineers and Energy Management System (EMS) providers coming up with new approaches in providing security to the...
In this paper, two robust adaptive control schemes are proposed for a class of uncertain nonlinear systems in a Brunovsky form with unknown dead-zone and sector nonlinearity. The design is based on the principle of sliding mode control and the use of Nussbaum-type function in solving the problem of the completely unknown control gain. The novel description of input nonlinearity which makes the control...
