In order to improve the practical level of intraday and real-time generation Scheduling,a hierarchical coordinated method is designed for intraday generation scheduling,real-time generation scheduling and automatic generation control (AGC).And a two-stage multi-combination optimization strategy for intraday and real-time generation scheduling is proposed. By using pre-trouble shooting techniques to design data source quality analysis and alarm logic,the overall flexibility,security and stability of the automation of generation scheduling real-time balance is improved.Actual application shows that the system is capable of achieving automatic optimal allocation of load deviation,effectively reducing manual intervention by operator, improving work efficiency and enhancing power grid security and economy.
