Loss assessment in a low-voltage distribution system

Accurate assessment of power loss in a low-voltage distribution system is still an important issue under present competitive environment. Even though, power flow analysis is still efficient to calculate technical power loss, it requires numerous data which may not be available for some utilities. For this reason, the loss assessment for a low-voltage distribution system is not easy when the demand of any customer load points is still unclear. Therefore, distribution utilities obviously require a more suitable algorithm with their available information to calculate their system power loss. This paper proposes an alternative algorithm to crop with this problem. The proposed approach has been tested with an actual system, a low-voltage distribution system with 16 customer load points. It is found that the proposed method can provide satisfactory results.
