Method, system and equipment for analyzing bearing capacity of distributed power supply technology of power distribution network

The invention discloses a method, a system and equipment for analyzing the technical bearing capacity of a distributed power supply of a power distribution network, relates to the technical field of power grid planning and electrical simulation modeling, and particularly relates to the method, the system and the equipment for analyzing the bearing capacity of the distributed power supply of the power distribution network. According to the invention, based on the determined network architecture and load power supply distribution, an optimization model and a calculation method for evaluating the bearing capacity of the multi-distributed power supply access power distribution network are established for each feeder line group or partition which is relatively independent electrically. According to the method, multiple types of security constraint conditions of different application scenes are analyzed and simplified, the calculation efficiency under the multi-point access condition is greatly improved, and a powe
