Research on Auxiliary Automatic Generator Control Marketing System in Hebei Grid

As the blueprint of China electric power revolution is drawn as transmission and distribution separation and competitive electricity retail, the market of ancillary service like AGC is urgent to develop. In this paper Auxiliary Automatic Generator Control Marketing (short for AAGCM) system is developed in Hebei grid. With the AAGCM system, the traditional AGC system can be developed to intelligent power utilization system. After obtaining real-time data from WAMS, the state estimation is carried out periodically. The formula of impact energy is given in the paper. With simulating AGC operations, it can be calculated for guiding the consumers to purchase ancillary service directly. The structure, hardware configuration and data exchange of the system are illustrated. The system is an important component of smart grid and power market, which leads to better power quality and the better pricing for both sides.
