The dual-carbon target and energy transformation promote the large-scale access of distributed renewable energy to rural power grids

resulting in a new rural power grid which have two typical characteristics including high proportion of new energy and bidirectional power flow. In the new rural power grid

technical challenges such as bidirectional power flow

reverse power transmission

voltage random fluctuation

inverter harmonics

protection configuration

and safe power consumption are becoming more and more prominent. The development status of China’s rural power grid

and the technical challenges faced by the rural power grid under the dual carbon target are analyzed

and the key measures and technical subjects are put forward to be studied in the construction of the new rural power grid

so as to provide methodological support for the planning and construction of the new rural power grid.
