With the rapid development of energy-saving and environmentally friendly power sources, such as solar photovoltaic and biomass power, the demand of distributed generation (DG) systems connected to the low-voltage distribution network is increasing. Distributed generation systems connected to the low-voltage distribution network will impact power quality, security and stability operation of power grid. So power companies should strengthen the supervision of DG. Based on the research of domestic and foreign DG monitoring standards, this paper sorts out the DG relevant provisions in existing distribution automation standards, and proposes some modified suggestions in the existing distribution automation standards to cope with DG connected to the distribution network.

To balance three-phase loads in distribution network with abundant of single-phase loads, the idea of three-phase adjustment and wiring method is proposed in this paper. Three-phase adjustment controller is designed, and the least load adjustment strategy is proposed, which can adjust the three-phase load to roughly balance automatically. The system can solve the serious three-phase unbalance problem of the lines with single-phase load, which may instead of capacitive compensation in low voltage distribution network. It can improve power quality and reduce network losses.
