Research on receptivity evaluation of distribution network based on optimal access of clean energy

In recent years, with the quick developments of large-scale and decentralized clean energy power station, distribution network faces greater pressure of acceptance and absorption of clean energy power grid. This paper analyzed major constraints of distribution network on clean energy accepting, and obtained the relationship between clean energy output and abandoned electricity. An optimal access method based on the target of interconnected capacity maximization of clean energy power station, satisfying interval number, line capacity, substation capacity and investment constraints, was innovatively proposed in this paper, which can direct clean energy power station access effectively. Based on the optimal access method, this paper researched overall evaluation and key evaluation of distribution network acceptance ability, weak links were analyzed furtherly. Finally, realizing of accurate investment and access ability promotion were illustrated with case.
