Transmission Loss Allocation Based on Circuit Theories and Orthogonal Projection

Poonam Kumari ^[7] | Kumar Dhiraj ^[2]

Abstract: The introduction of deregulation and subsequent open access policy in electricity sector has brought competition in energy market. Allocation of transmission loss has become a contentious issue among the electricity producers and consumers. A closed form solution for transmission loss allocation does not exist due to the fact that transmission loss is a highly non-linear function of system states and it is a non-separable quantity. In absence of a closed form solution different utilities use different methods for transmission loss allocation. Most of these techniques involve complex mathematical operations and time consuming computations. A new transmission loss allocation based on circuit theory and orthogonal projection has been developed and presented in this thesis. The orthogonal projection computes loss allocation much faster than other methods. A relatively short execution time of this method makes it a suitable candidate for being a part of a real time decision making process. Most independent system variables can be used as inputs to this method which in turn makes the loss allocation procedure responsive to practical situations. In this method we calculate the following: A. Review of the Calculations for the Share on Branch Current B. Current Projection Component C. Power Flow Decomposition D. Branch Loss Allocation
