“…ATC is defined as the TTC less than the transmission reliability margin (TRM), less than the sum of existing transmission commitments (ETC) and capacity benefit margin (CBM) [2,16,17]. The TRM is the amount of transmission capability necessary to ensure that the interconnected system is secure under a reasonable range of uncertainties in system conditions.…”

SUMMARYThis paper presents a fast and accurate method to determine the power transfer so-called the available transfer capability (ATC). The methodology utilizes the cubic-spline interpolation technique that is incorporated into the Ralston's method in order to provide fast and accurate assessment of ATC. The Ralston's method is used to predict the two trajectory points of voltage magnitude (U), power flow (S), and maximum generator rotor angle difference (Dd). Then, the cubic-spline interpolation technique is used to accurately trace the P-U, P-S, or P-Dd curves between two points of trajectory. The P-U, P-S, and P-Dd curves represent as the variations of voltage magnitude, power flow and maximum generator rotor angle difference due to the increase of power transfer or ATC. The actual value of ATC is then determined when either the voltage magnitude limit, power flow limit or generator rotor angle difference limit intersects the curve. The effectiveness of the proposed method is verified by referring to the results of ATC for a case study of 2737-Polish system and 39-New England bus system. The proposed method gives a satisfactorily accurate and fast computation of ATC as compared to recursive AC power flow method.

“…A straightforward solution is constructing new transmission lines, but this faces a series of problems, such as large investments and environmental restrictions [1][2][3][4][5][6]. For example, establishing a new transmission line in Alberta is not only a political, but also a controversial problem [7].…”

Abstract:With the increasing consumption of electric energy, how to improve the capacity of transmission lines within safe margins is an urgent problem to be solved. This paper presents a transient thermal rating method under real-time meteorological conditions. The result of thermal ratings under different conditions shows that this rating approach can significantly increase the capacity of the line. As some of the most critical variables are remaining time and initial temperature, their influence upon the rating is studied. The method of statistical analysis is used to determine the ampacity at different risk levels. The result indicates that with smaller remaining time, the ampacities are larger, and with larger ampacities, the risk of thermal overload is greater. The choice of risk level would heavily affect the values of ampacity.

“…In addition, societal and environmental concerns often cause lengthy approval processes for new constructions and/or upgrades. Alternative solutions concentrate on a better utilization of existing transmission lines through improved methods of thermal rating [1,2], or on identification of maximum loadability limits [3][4][5][6][7].…”
