With the rapid development of rural economy in China

the low voltage phenomenon in the rural power grid is more and more frequent

therefore the effective measures need to be taken. Unlike such low voltage control means of rural power grid as rising the requirement management of the low voltage customer’s load

strengthening operation and management of intermediate and low voltage supply and distribution facilities and adding the voltage regulation device of 10 kV feeder

the low voltage control of rural distribution grid is pushed to the level of smart grid construction

the real time monitoring

data gathering and integrated control of automation and the direction for coordinating high and intermediate voltage rural distribution grid to achieve joint is pointed. Finally

the penalty function is introduced with combination of rural grid load characteristic to test certain rural low voltage distribution grid and verify the algorithm feasibility.
