Abstract:

In order to formulate the rational development strategy of renewable energy, a method of renewable energy accommodation under highly-resilient power grid is proposed. Firstly, the impact of renewable energy integration is analyzed, and then a framework for renewable energy accommodation under highly-esilient power grid is established. The capacity of renewable energy accommodation is improved by the coordinated dispatch of power supply, grid and load, and a variety of renewable energy accommodation projects are proposed. Finally, the "mobile transformer" and the retired battery access program are adopted to reduce the equivalent load peak-valley difference and to improve the ability of system adjustment. The optimal configuration capacity of the retired battery is obtained through the sensitivity analysis of mobile transformer, and the actual calculation examples show that the proposed method can promote the renewable energy accommodation.
