Loss allocation in radial distribution networks with different load models and distributed generations

Under deregulation and competitive environment, equitable allocation of losses with increasing loads and participation of new generations is a challenging task. This study proposes a solution to loss allocation problem for radial distribution network with various load models and distributed generation (DG). The location, rating and time evolution of the loads and DGs connected to the network are considered in this problem. It traces not only real but also reactive power to identify the actual contribution of loads and DGs into the total network losses. It develops a direct relation between injected current/power of consumers/DGs and network losses. To allocate the fair losses, the proposed method assigns the cross-terms by employing the geometric scheme of allocation. To show the effectiveness of the proposed method, it has been tested on 33-node radial network. To validate the proposed method, it has been compared with other methods.
