Integration of Increasing Wind Power into Electricity Grid in China: With a Focus on Institutional Matters

Abstract: This thesis focuses on what can be done from institutional prospective to integrate increasing amount of wind power to the system in China. By looking into what are current grid integration problems in China at institutional level and how the best insternational practice, the Danish grid integration, look like and the lessons from institutional prospective and comparison between two systems are made. It became clear that 1) overall planning of wind power development at central and local levels, among various key stakeholders and finally between wind pwor plants and other power plants shall be further coordinated. Responsibilities in various authorities shall be clearly defined to avoid overlap; 2) Grid integration management system including setup and enforcement of various standards, certification and testing system, mechism to help to improve predicting and forcasting forcasting capacity, and last, the capacity in key institutes are key to the improvement; 3) Policies to prioritize wind power in the dispatching shall be issued and enforced as mandatory, while more flexible price and supporting scheme including environemtn tax on conventional power plants, and Green Certificate Scheme shall be considered. 4) At last flexibility on demand side is needed to better facilitate with shifting the peak load, and dispatching. In conclusion, from institutional prospective, China needs to have a better grid and operation management, policy framework, and and incentives to build a robust and flexible power system to integrate increasing wind power.
