solar panels and renewable energy distributed generation is according to solar street lamps, and the influence of wind speed and other natural factors. It has obvious random and intermittent characteristics, output power fluctuation range, especially the power electronic devices in the distributed power generation equipment, users and is widely used in traditional power grid. The bidirectional interaction for the safe and economic operation of power grid and power quality has important influence. Traditional grid especially the certainty of the distribution network planning and operational theory is difficult to meet the large-scale access of polymorphism distributed energy. Consider the implementation of active power distribution network based on hierarchical storage national energy strategy and the rationalization of renewable energy. Use and improvement of the environment has important economic and social significance.
the traditional distribution network is a kind of single-phase flow of radiant power distribution network, an urgent need to develop.
