Recently, the paper "Provincial renewable energy dispatch optimization in line with Renewable Portfolio Standard policy in China" by Professor Biying Yu and doctoral student Zhao Zihao of the CEEP-BIT was published in the international journal "Renewable Energy".

China has proposed the Renewable Portfolio Standard (RPS) to advance the stable development of renewable energy. This RPS requires each province to achieve a stated minimum share of renewable energy power in the total provincial power generation. However, China's renewable energy resource endowments are unevenly distributed, and there is an obvious mismatch between the actual capability of generating renewable power and the assigned responsibility for the share of renewable energy power based on the RPS in some provinces. Therefore, this study aims to optimize the renewable power dispatching strategy across provinces for satisfying the RPS requirements in China and to assess the corresponding pressure for each province. This article further evaluates the pressure on achieving RPS target faced by each province.

The results indicate that it is necessary to dispatch 395.2 and 140.4 TWh of hydropower and non-hydropower nationwide, respectively, in 2022 to fulfill the RPS target when the COVID-19 is effectively controlled worldwide. If COVID-19 cannot be effectively controlled, 376.6 and 127.8 TWh of hydropower and non-hydropower must be dispatched nationwide to fill the gap. Beijing, Tianjin, Shanghai and Zhejiang face higher pressures under the RPS target. Finally, a path for each province to achieve its RPS target is proposed.
