The Cost

<p>Addressing loss due to transmission and its cost allocation in deregulated electricity market is an  essential issue. Independent System Operator (ISO) provides the active power loss from the generators and the associated cost is allocated to the concerned parties in a fair way. The generators and loads participate in the loss/cost allocation process. The highlight of the paper is that the effect of mutual inductance (MI) that exists on transmission line in transmission loss/cost allocation process for multlateral contracts is illustrated. To demonstrate the effect of mutual inductance, the results of  existing loss allocation methods like penalized quoted cost (PQC) based approach are discussed. Effect of mutual inductance is presented using an IEEE 30 bus system. The simulation results are carried out using MATLAB R2014a. The result shows that mutual inductance has a significant impact on transmission loss and hence cannot be ignored.</p>

A New Technique

In a present day a necessity for fair allocation of transmission loss in a deregulated electricity market. This paper presents modifiedZbus loss allocation method to calculate the allocation of transmission loss loss . The procedure depends on straightforward circuit laws and doesn't include any suppositions. results obtained for IEEE 14 Bus system are analysed with the other present methods

Linear Nature

In the current scenario of the electricity market in the world the cost allocation became the thematic part and the essential usage to individual distributor and to the consumer. Allocation is nothing but a share of anything that been shared in the equal amount to the assigned terms of the quantity. Here in the power sector, losses and the respective costs have been shared among the generators and the loads. To achieve the linear nature and invariant characteristics, allocation of losses is done. To such allocation of losses there are many methods, popular methods of them named, Proportional Sharing Principle Method and Aumann-Shapley Method are compared in this paper based on loss and cost allocation, and results are verified through Mat lab platform.

In a deregulated electricity market the generating and distribution companies enter into various levels of contracts for primary energy transaction. In real time, the losses due to these contracts must be economically supplied by Independent system operators (ISOs). Graph Theory is employed in many fields of engineering especially in transmission loss allocation problem to formulate a given network’s behavior. Graph theory based loss allocation method gives satisfactory results over the other existing methods in terms of technical suitability and various transactions. Loop based representation approach is used for the network formulation. Compared to other loss allocation methods, this method distributes losses to the different participants in a lucid manner. In this paper, a comparison of graph theory based loss allocation method over the other existing methods like proportional sharing, Z bus and modified Z bus loss allocation is made. The results are shown for a sample 4 bus system and IEEE14 bus system. The simulation is carried out using MATLAB (R 2014a).
