Research and Implementation of Power Grid Simulation Data Management Platform

Based on an in-depth analysis of the requirements of large interconnected power grids for simulation data management, the corresponding solutions are proposed. The paper studies the technology for extracting multi-time-section power grid model and the data processing technology for addressing bus topology change, and develops a data management platform for power grid simulation, which has been successfully applied to the State Grid Simulation Center, and supported dozens of units such as dispatching center for the preparation of joint calculation data, and become a platform of data management and distribution for the State Grid. The platform has effectively solved the problems of long data preparation period and low work efficiency of ultra-large-scale power grids, unified the data sources for simulation calculation in different areas, realized the remote maintenance, centralized management and rolling update of power grid simulation data, and improved the maintenance efficiency and quality of power grid simulation data, and provided strong support for the safe and stable operation of UHV AC/DC hybrid power grid.
