Influencing mechanisms of renewable energy development on carbon
First, this paper only analyzes the impact of renewable energy on carbon emission intensity from the perspective of renewable energy power generation, but the production, transmission, and consumption of renewable energy occur simultaneously in the operation of the power system, so it is necessary to further analyze the impact of renewable
Carbon Management for Modern Power System: An Overview
Being the primary source of global carbon emissions, the power sector is actively undergoing a low-carbon transition. Renewable energy sources (RES), enabled by technologies like solar energy capture [7] and offshore wind farms [8], are effectively integrating clean energy, such as solar and wind power, into the existing power system.
