Some new concepts in modern automatic generation control realization

Modern power generation control areas consist of large power plants and many industrial customers. High quality supply of the electricity increases the demand for automatic generation control in North-China Electric Power Network. For quickly satisfying the large load changes or other disturbances and enhancing the safety of the power system, the feed forward strategy and the nonlinear governor-boiler model in automatic generation control are investigated in this paper. Some new concepts, such as developing a new algorithm for more effective control; considering the whole boiler-turbine-generator model instead of only the governor-boiler model for the load disturbances; understanding the interaction between the fast area control error loop and slow governor-boiler inner loop, are discussed. Simulations of the automatic generation control with feed forward and PI controller have shown that these ideas are helpful to the automatic generation control realization
