Abstract
The electrical industry has been continuously in the process of restructuring in the recent years. The open and competitive market demands the calculation of Available Transfer Capability(ATC).
The ATC between source and sink node indicates maximum additional MW that can be transferred without violating the operating and security constraints. [1]
The ATC needs to be computed and updated on hourly and daily basis and made available on an open access.
This paper utilizes the DC power flow model and linear optimization technique using MATLAB to determine ATC for bilateral transactions.
The DC load flow analysis can be utilized as a first level study as it is an approximate but fast method.
An IEEE 24 bus RTS [2] is studied and the results are presented.
