Discussion on the AGC Improved Mode for Direct Trading between Large Consumers and Generators

Automatic generation control(AGC) which is one of the most important function of energy management system(EMS) can increase the frequency quality,economic benefit and management level of interconnected power systems effectively. Our old frequency control way is mostly TBC mode. But with in-depth development and perfection of reform in the electric power market system,the old control mode has become the exchange block. Further more direct trading between big customers and generators has become increasingly urgent. To promote in-depth implementation of the power direct supply operation mode,this paper presents a new improved AGC mode based on TBC to satisfy the demand of direct trading between big customers and generators.
