“…Electric power industry is being restructured globally, in recent times, with transmission open access being an essential part of the restructuring . This transformation has brought up new challenges, which threatens, to a greater extent, the reliability of power system operations . Such challenges include loss allocation issues, power‐flow tracing problem, transmission pricing problem, network congestion management problem, ancillary services, and decisions on the scheduling of generators to meet the network demands .…”

Summary This paper presents an alternative approach of Inherent Structural Characteristics Theory (ISCT), for solving loss allocation to network participants as well as generation‐to‐load matching problems in a deregulated environment. The mathematical formulations of ISCT, based on the fundamental circuit theory laws, are revisited. A Generation‐to‐Load Allocation Coefficient (GLAC) matrix for solving generation‐to‐load allocation and network loss allocation to load problems, for efficient transmission pricing, is formulated. The allocation of real and reactive power contributions, by individual generator, required to serve the network demands is also determined on the basis of the GLAC matrix. Total network losses are determined and allocated to individual network loads based on GLAC matrix. The approach is demonstrated using the standard IEEE 30 bus network. The results obtained are compared with that obtained using graph theory approach based on the solved power flow. The comparison of the results shows that the ISCT approach is reasonable and it is a good signal, which could be useful for pricing of electricity by the market regulators.

Abstract-In the deregulated power system environment the transmission loss plays an important role. Both its allocation and reduction impact a lot on economic consideration. Due to the nonlinearity nature, the allocation of transmission loss among different utilities creates a challenging task. This paper proposes a new formula for transmission loss allocation based on actual usage of line. It splits a common transmission line into as many sub-lines corresponding to the number of loads attached to it. It divides the total loss of the common line among the sub-lines in proportion to their individual power sharing. The net loss allocated to a particular load is the combination of individual loss occurring in different sub-lines which are concerned to the said load under the whole system. To apply this formula, the load flow solution of the system network along with the power flow tracing of lossy lines are computed. This paper uses Newton-Raphson based iterative technique to obtain the load flow solutions and proportional sharing method for power flow tracing. The proposed formula is applied to a six-bus case to prove its viability and subsequently used to find the loss allocation in IEEE-14 and IEEE-30 bus systems. Relative Electrical Distance (RED) concept which is based on topology of the system and readjustment of generations has been utilized to reduce the loss in both the systems. The amounts of loss reduction in both the cases are found to be significant. Again the loss allocations of the two systems are worked out using the proposed formula and finally comparison of loss allocations before and after the loss reduction have been presented.

“…This paper proposed a method to separate losses for restructured power system based on circulating current method with the help and some modification in N-R method. This method also helps for the ideal location and rating of compensation devices so that we obtain very good performance of the line with minimum losses [4,9]. For that, basic concepts can be used to solve particular problem means this paper gives the solution of loss separation of each line, which is produced by each generators and each loads.…”
