An Estimation Technique to Assign Contribution Factors for Loop Flows in an Interconnected Power System
Abstract:This article describes the significance of loop flows in an interconnected electric power system. Loop flows (unscheduled flows) are the difference between scheduled and actual power flows. A brief discussion of the consequences of loop flow is given. The article illustrates a new method of identifying the contributions of the loop flows occurring in a system to the participating utilities by means of a contribution factor matrix. A method to estimate the loop flows in the system using a type of Lp estimation is described, and the estimation technique is further employed in designing the contribution factor matrix. The potential application is in transmission pricing.
