Review on the regulation capability of multiple generation resources and suggestions for generation-side flexibility improvement

With the large-scale access of renewable energy, it is essential to explore the flexibility of the power system, which is closely related to the regulation capability of multiple generation resources. However, the regulation capability of the existing generation resources has not been fully reviewed, hindering the improvement of generation-side flexibility and accommodation of renewable energy. Therefore, this paper makes a review of multiple generation resources focusing on their regulation capability. Firstly, the key issues in peak shaving of three typical generation resources, including nuclear power, external power and distributed small hydropower, are summarized. Next, the key technologies for the regulation of multiple generation resources are studied. Moreover, the potential of coordinated adjustment of multiple power generation resources is explored. Finally, based on the peak shaving experience abroad and the actual situation in Zhejiang Province, suggestions to improve the generation-side flexibility are put forward.
