Transfer capability is a measure of the strength of the interconnection between utilities, areas, power pools or regions including the transmission system of these entities. Most of these entities determine nonsimultaneous transfer capabilities on a regular basis, generally using some kind of a linearized technique. However, the usefulness of this information is limited as the impact of other transfers in a multiarea system cannot be easily and accurately determined from these results. Therefore, to assess the industry's need, experience and concerns in the area of Simultaneous Transfer Capability (STC) analysis, EPRI funded a survey, RP2473-29, Determination of Multiarea Transfer Capability: Is a Methodology Needed '' Based on the results of this survey and an EPRI sponsored workshop to identify and prioritize research needs, EPRI initiated this project RP3140-1. The objective of this project is to identify the preferred methodology and direction for developing software which will determine STCs between areas in a multiarea system. As described in the report, central to the determination of STC is an optimization problem which can be viewed as a variant of security constrained optimal power flow (SCOPF) problems. The solution methodology recommends, as a minimum, development and integration of three main modular processes: linear programming (LP) optimization, contingency screening, and a full featured AC power flow. Because of the complexity and size of the problem, these major modules must be developed implementing state-of-the-art methods. The efficient implementation of the algorithms used in each module cannot be overemphasized. Otherwise, speed, accuracy and program size would be seriously compromised.
