Net rack load balancing method based on regional new energy adjustment

The invention relates to the technical field of power grid planning, and particularly discloses a grid load balancing method based on regional new energy adjustment, which comprises the following steps of: 1, analyzing a feeder line of each photovoltaic user, and calculating photovoltaic capacity which can be accessed by each feeder line so as to obtain accumulated accessible photovoltaic quantity; and step 2, based on the operation data of the distribution network line and the daily load data of the user, on the premise of considering the output characteristics of the new energy, analyzing and calculating the distribution network load size and the network loss value between the main line segments, accurately determining the optimal operation mode, and performing compensation allocation on the heavy-load main transformer, the line and the distribution transformer. According to the method, the defects in the prior art are overcome, the optimal operation interval of the line and the main transformer is sought u
