Four different scenarios, energy storage without interconnection, installing additional renewable energy sources without interconnection, energy storage with interconnection, and installing additional RE sources with interconnection, were considered for the economic benefit analysis. A comparative study of these four scenarios was conducted to identify the best option for achieving hourly power balance. Further, sensitivity analysis was carried out to demonstrate the robustness of the results. Electricity interconnection between CN and EU decreases the annual additional costs by more than 30% when compared to the absence of interconnection, which demonstrates the necessity and benefits of CN-EU electricity interconnection.展开更多

Based on the construction of the reserves, the contributions of the reserves of various categories to the biodiversity conservation and the existed shortages for the reserve construction in China were analyzed thoroughly in this paper.展开更多

A comparative study of these four scenarios was conducted to identify the best option for achieving hourly power balance.
