A Key Method of Intelligent Load Control Based on Dual Topology Check of Real Temporal and State Estimation

During important power supply periods such as kurtosis summer, the power of the receiving end of the grid will be seriously unbalanced, and the main transformer and important transmission sections will run in over-heavy load. Once the N-1 failure of the main equipment occurs, the power shortage will be caused, and the safety carrying capacity of the grid will be seriously challenged. It is urgent to remove batch loads quickly, accurately and efficiently to balance the power of the grid. This study describes the design architecture of a new intelligent load control system, proposes a load control method based on real temporal and state estimation topology check. Forming a load control plan with “double confirmation” and safety check after comprehensive consideration of control objectives, load table control rotation priority, listing, power preservation, etc. Through the actual example, the system can realize the rapid and accurate removal of target loads, which has a good application and promotion value to ensure the safety, stability and economic operation of power grid.
