Current status and prospects of data sharing between buildings andpower grids for source-load interaction

The fusion of digital technology and energy is a crucial tool for advancing green and low-carbon technology, with data sharing serving as a key lever to promote deep integration of industries and drive innovation across the entire value chain. In the future new power system, source-load interaction based on data sharing is expected to become a critical element in advancing the development of smart power grids and the low-carbon transformation of building energy systems. Effectively coordinating between user-side entities like buildings and the power system, and achieving seamless data exchange between supply and demand sides, is an urgent and essential issue to explore. This paper investigates the current status and development trends of power data sharing between user-side entities like buildings and the supply side of the power system. Firstly, it examines the monitoring and application status of power data on both the supply and demand sides of buildings. Subsequently, a detailed review is provided of the current interaction modes and mechanisms between buildings and the power grid. Finally, in consideration of future development needs, relevant trends and policy suggestions are proposed, aiming to provide valuable insights for the low-carbon development of building energy systems and their better integration into the entire low-carbon energy system.
