Power distribution network comprising direct-current distributed power supply and analysis method of comprehensive load characteristics of power distribution network

The invention relates to a power distribution network comprising a direct-current distributed power supply and an analysis method of comprehensive load characteristics of the power distribution network. The power distribution network comprises static loads, a dynamic load bus and comprehensive loads, wherein the static loads are equivalent static loads formed by combining static load elements and the direct-current distributed power supply, a model structure of the comprehensive loads is a generalized comprehensive load model structure and comprises a reactive compensation device, static loads, induction motor loads, an equivalent power supply, a power distribution network equivalent impedor, the reactive compensation device, the static loads, the equivalent power supply and an induction motor are connected in parallel and are connected to an external system through the power distribution network equivalent impedor. The model structure of the comprehensive loads adopted in the power distribution network can integrally describe various load characteristics of nodes, and the problem that after a large number of distributed power generation devices are connected to the power distribution network, the power distribution network affects the comprehensive load characteristics is solved.
