Research on Unified Cognitive System of Renewable Energy Utilization Rate

Abstract

China’s requirements of renewable energy utilization rate target have greatly promoted vigorous development of renewable energy industry and rapid increase of its scale. But with further increase of renewable energy’ proportion, strictly maintaining this target will bring negative effects. This paper refers to public knowledge of hydropower development, proposes and defines three utilization rates of renewable energy, respectively are theoretical utilization rate, technical utilization rate, economical utilization rate. Based on a power system operation simulation model, this paper also gives an example of three utilization rates, and makes analysis from the perspective of sharing responsibility between renewable energy and traditional energy.
