Problems solved by technology

The loss of each line within the power supply radius of the planned low-voltage station area is not optimal. The power supply radius can be adjusted through loss calculation and adjusted loss prediction. However, due to the theoretical loss calculation, some idealized assumptions are required. Moreover, there are problems such as three-phase unbalance, delay and parameter instability in the actual power grid, which will lead to inaccurate losses calculated according to theory, and the power supply radius determined according to theoretical losses is not optimal.
