BENEFITS OF WHEELING ECONOMY ENERGY IN CANADA - QUANTIFICATION AND SENSITIVITY ANALYSIS

The paper describes the studies carried out by the National Energy Boa rd to quantify potential wheeling benefits as part of its review of po ssible measures for enhancing transmission access in Canada. Computer simulations were performed on a planning time horizon to determine pot ential benefits from bilateral exchanges of economy energy and the add itional benefits which could result from various wheeling arrangements . The simulations modelled the interconnected power systems of eastern Canada and the neighbouring American utilities which make up the Nort heast Power Coordinating Council. From these simulations, the potentia l benefits for each system involved as well as the net potential benef its were determined. The CPU time for the simulations ranged from 14 h to 46 h on a VAX 8200 minicomputer. Sensitivity analyses were also pe rformed to establish the sensitivity of the results to some operationa l assumptions and parameters used in the studies.
