Requirements and architecture for energy management services

Abstract

This Recommendation describes requirements, scenarios and functional architecture for user-side Energy Management Service (EMS) where energy consumption equipment with heterogeneous metering and control capacities coexist. In user-side EMS systems, energy consumption data for both single device and device group are needed to be collected and these devices can be controlled by coarse-grained (on-off state) and fine-grained instructions. Furthermore, such operations are executed manually or automatically. The user-side EMS system makes energy-saving decisions based on multiple factors, such as the demands and optimization policies from the users, the pricing strategies from the suppliers, government subsidies, device status et al.
