A Novel Control Strategy of Space Heating Equipment for Peak Shaving Based on Operating Data Xingli Ding, Xudong Yang



With the penetration of renewable generation and terminal electrification, there is a huge demand of peak shaving for power system. Heating equipment are recognized as flexible resources for peak shaving, since there are numerous controllable variables and great power in heating systems, and buildings have significant thermal inertia.
This paper proposed a novel control strategy based on operating data to coordinate distributed space heating equipment across numerous residential households. Heating characteristics of each households, thermal inertial of indoor air, and power characteristics of heating equipment were obtained based on operating data analysis. Thereafter, load shifting potential under different scenarios were determined through historical operating data and current operational status. Based on the principle of minimal impact on indoor air and fairness, target heating equipment was adjusted by remote control instructions. Additionally, local adjustment by users has priority over remote control to assure thermal comfort requirements, and participation in regulation brings subsidies to users. A case study shows the strategy can produce 8% peak shaving and 27% reduction of peak-valley ratio under the same heating cost.
Moreover, the purpose of regulation could be modified according to specific needs, including the cost saving of induvial heating, and the reduction of peak power of the grid.
