TTC and CBM Calculation of IEEE-30 Bus System

Abstract

With the recent trend towards deregulating power systems around the world, transfer capability computation emerges as the key issue to a smoothly running power market with multiple transactions. A key concept in the restructuring of the electric power industry is the ability to accurately and rapidly quantify the capabilities of the transmission system. Total Transfer Capability (TTC) is defined as the amount of electric power that can be transferred over the interconnected transmission network in a reliable manner while meeting all of a specific set of defined pre- and post-contingency system conditions. Available Transfer Capability (ATC) is a measure of the transfer capability remaining in the physical transmission network for further commercial activity over and above already committed uses. In this paper, MATLAB software is used to determine the Total Transfer Capability (TTC) of power transfers between different control areas in deregulated power systems without violating system constraints such as thermal, voltage, and stability constraints. The main aim of this paper is to calculate total transfer capability and capacity benefit margin of IEEE 30-bus reliability test system (RTS) for calculation of ATC. The IEEE 30-bus RTS is partitioned into 3 control areas. It is required to calculate the TTC for each control area to enhance the open access of a transmission network by providing a market signal of the capability of transmission systems to deliver electric energy.
