Line Loss Analysis and Reduction Method for Small Hydropower Embedded Distribution Network

摘要

The distribution system power flow during flood season and dry season varies greatly, due to the impact of the output fluctuation of small hydropower in different seasons. Hence, it is necessary to optimize and adjust the grid structure, operation mode and load level for the sake of distribution network loss minimization. A distribution network operation analysis method is proposed. Then the impact of different operation modes of small hydropower on the power grid is comprehensively analyzed. The integrated power and line loss management system and its theoretical line loss calculation module are used to verify the impact of different operation modes of small hydropower. Finally, the optimized solutions are effectively conducted to reduce the line loss.
