Relates to the technical field of intelligent power grids, and provides a novel intelligent direct-current interconnection distribution network power distribution device which comprises an intelligent direct-current interconnection device, and through intelligent control and standardized power distribution, rapid direct-current interconnection between power distribution stations is achieved, and power ataxia between the stations is achieved. According to the invention, through the intelligent control method and the standardized power distribution device, in the adjacent areas where distributed power supply grid connection is large and user load difference is large and energy consumption is unbalanced, through the intelligent direct current interconnection system, power mutual aid and energy complementation among multiple areas are realized, and long-term reliable and stable operation of the power distribution systems of the two areas is ensured.
Description
technical field [0001] The invention relates to the technical field of smart grids, in particular to a novel smart DC interconnection distribution network power distribution device and a control method. Background technique [0002] Under the environment of steadily advancing low-carbon emissions, photovoltaic power generation continues to advance and develops rapidly, especially photovoltaic power generation for users. At present, some rural power distribution stations mostly use small-capacity and multi-point distribution. Each administrative village is equipped with multiple 200 (400) kVA transformers, each transformer has an average load of 30 kilowatts, and the photovoltaic access capacity reaches 100 kilowatts. It is very easy to cause reverse power in the station area when it is full, and even cause reverse heavy overload. It will cause the distribution transformer to be overloaded in the reverse direction and greatly increase the line loss; at the same time, it will...
