Transmission loss and Fair allocation of deregulated market participants is essential in the present restructured electricity markets.This paper proposes a direct method to find the loss allocation. The implementation of market mechanisms to remunerate distributed generation should take into account a non-discriminatory access to distribution networks. In consequence, power losses of distribution network must be fairly allocated among the all distributed generators and consumers. Several methods for power loss cost allocation have been proposed in the literature, divided basically into two groups. Firstly, methods as postage stamp, mw-mile, circuit based and proportional sharing have been supported on an arbitrary allocation of power losses between consumers and generators. The methodology is based on simple circuit laws and does not involve any assumptions. Considering the real power injection and real power loss contribution factors loss allocation can be done. Case study of the proposed loss allocation methodology is conducted on 2 bus and 6 bus system.
