“…Therefore, two algorithms for upstream tracing and downstream tracing of the complex power were proposed [11]. Some other methods, such as bus-wise method based on path-integrals [4], modified Z-bus [12], usage-based [13], and artificial intelligence [14] solutions for loss allocation, were also surveyed lately.…”

Transmission loss has a considerable effect in overall power generation. For fairly distributing the charge of losses to generators and consumers in a deregulated power system, the allocation of this loss is very important. Gametheoretic methods seem fairer for share determination of each participant of a coalition with no discrimination. In this paper, the active and reactive power transmission losses are allocated to bilateral transactions simultaneously through load flow calculations and cooperative game theory solutions. The loss allocation problem and each bilateral transaction are treated as a game and a player of the game, correspondingly. Two game theory-based approaches, the Shapley value and the τ -value, are surveyed. The former is the most relevant game theory allocation method, while the latter is a novel approach. The influences of all loss allocation game players and bilateral bargains on transmission loss are considered.These two proposed methods are applied to a simple 6-bus network and the modified IEEE 57-bus test system. In the 6-bus network positive MVA loss allocations and in the IEEE 57-bus system negative MVA loss allocations are studied.Finally, the results of allocation procedures are compared to each other.

“…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 .…”

“…These services can be provided either by the network generating units or through the use of transmission network components, which could be static VAR compensators or shunt capacitors located at few buses within the network . Furthermore, the contribution of the individual generating company to consumers within the network, which is an important issue in the transmission service pricing, will be easily determined . Moreover, in practical power systems, a substantial amount, which could be up to millions of dollars, is associated with the system losses.…”

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.

“…Then, to obtain accurately, the author in [14] proposed an approach using neural networks and other methods using the modified nodal equations to identify the actual power loss allocation for the generator and the load [15]. Meanwhile, [16] proposed a loss allocation method based on circuit theory. A new method was verified by [17] for allocating the user's loss contribution in each branch, called as Equivalent Bilateral Exchange (EBE).…”

-The industry has rapidly growth and energy supply technology advanced are become main factor which to contribute of the harmonic losses. This problem is one aspect that may affect the capability of the transmission line and also to the efficiency of electricity. This paper proposes a new scheme to allocate the cost pertaining to transmission loss due to harmonics. The proposed method, called as Generalized Harmonic Distribution Factor, uses the principle of proportional sharing method to allocate the losses among the transmission users especially for industry consumers. The IEEE 14-and 30 bus test system is used to compare the proposed method with existing method. The results showed that the proposed method provided a scheme better in allocating the cost of transmission loss, which could encourage the users to minimize the losses.
