The problems and solutions for large-scale concentrated integration of wind power to partially weak regional power grid

Within northeast china, most of the areas where have abundant wind power resources are located in remote under developing regions. They usually have weak regional power grid. With more wind power system in large scale are connected into such weak regional power grid, it get more attention on the conflict of the wind power development and the stable and safe operation of the partially weak regional power grid. Analyzing the effect has become an urgent topic. This paper starts from a wind power model, use the actual power grid as example and apply time-domain simulation method to study the effect of wind power integration to partially weak regional power grid. We give some preliminary advices and solutions for this problem. The research results will be promote more science and reasonable of wind power development.
