The invention provides a shared distributed energy storage configuration method considering inter-transformer area interconnection, which comprises the following steps of: arranging a corresponding power flow controller on each transformer area, and interconnecting two or more transformer areas with complementary transformer area net power values through the power flow controllers to form an internet circuit, and power dispatching and transmission are carried out through a system power flow direction formed by surplus photovoltaic power of each transformer area and a load demand power state. All the transformer areas are connected with one another through the power flow controllers to form an internet path which is provided with a shared energy storage battery. The method has the beneficial effects that the capacity optimization method of the shared energy storage and the bidirectional converter, which takes the maximum distributed photovoltaic permeability as a target, is provided aiming at the influence of
