Research on the Calculation Method for External Dispatch Constraints of Cascade Hydropower Stations Considering the Maintenance of Transmission Equipment
This article proposes a calculation method for external dispatch constraints of cascade hydropower stations considering the maintenance of transmission equipment.Based on the modeling of unstructured data,such as dispatch operation regulations,a dispatch constraint table for the cascade hydropower station is constructed.By integrating the maintenance schedule of transmission equipment,the external output constraints of the cascade hydropower station are calculated.The research findings have been applied in cascade hydropower stations and simulated calculations were performed using historical data.The results indicate that the calculated outcomes are consistent with actual conditions,demonstrating an efficient and accurate method for calculating the external dispatch constraints of cascade hydropower stations.This has important theoretical and practical significance for enhancing the capacity for clean energy consumption and planning the construction of power grid lines.
