Research on Instability of Distributed Renewable Energy Power Access to Distribution Network

Rapid increase of renewable energy gross capacity, Causes coordinated development problems of distributed power supply and power network. This paper provides a new method, which is based on power supply type, voltage level and city form to achieve adjustment of energy strategy and power development. Operating state of the power grid is fully considered to ensure accuracy of the adaptability study of the distribution network, which contains reliability, load ratio, short-circuit current, power quality. This article presents suggestions for planning and construction on distribution network of different types.
