A Real-time Linkage Preparation Method for Unit Interconnection Line Planning Considering Safety Constraints and Allocation Principles

Through thorough field research and based on actual needs, a real-time linkage method for compiling unit connection line plans considering safety constraints and allocation principles has been proposed. This method not only enables unified management of the start stop plan and corresponding connection line plans of pumping and storage units in the North China region, but also enables automatic modification of the corresponding provincial network connection line plan values according to the capacity allocation ratio under any start-up mode of pumping and storage units, and issues them for execution. At the same time, it considers unit output constraints, unit ramp rate constraints, unit ramp constraints, unit start stop constraints, connection line power and ramp constraints, etc.
