Determination of available transfer capability under dynamic condition

Abstract

ATC is an index which is determined by considering both static and dynamic constraints. Several researchers have proposed various methods for determining SATC, including DC load flow based, stochastic, continuation power flow, to mention but a few considerations of dynamic constraints. The methods to determine dynamic ATC include the use of neural networks, and so on. The existing methods are quite complicated and considerably slow in determining ATC especially when TSA is involved in the process. In this project, a method to determine ATC under dynamic condition using Fast Decoupled Power Flow Solution has been proposed and developed. This technique is a powerful analytical tool involving numerical analysis based on a famous Newton Raphson method which is used for routine solution. Matlab has been used as a programming tool. MATLAB is a high-level technical computing language with interactive environment for algorithm development, data visualization, data analysis. The developed program has been tested on IEEE 30 bus practical power system. The results obtained from the tests have been compared with the results from the previous study on dynamic ATC. The results show that the proposed technique is comparably accurate and faster than the existing method.
