Abstract
With the development of the smart grid in China, new opportunities for
responsive industrial loads to participate in the provision of ancillary
services (AS) will become accessible. This paper summarizes AS in China
and analyzes the necessary characteristics and advantages of industrial
users to provide AS according to their response mechanism. Cement
manufacturing and aluminum smelter processes are selected as two
representatives of responsive industrial loads. An agent-based model
that includes generation, industrial user, and grid agents is proposed.
Using two case studies, we analyze the integrated power management of
conventional units and industrial loads in day-ahead and real-time AS
scheduling based on real device parameters, price mechanisms and
production data. The simulation results indicate that the participation
of responsive industrial loads in the provision of AS, in China, can
improve the coal consumption rate and the system-wide load factor as
well as reduce the total system cost for the provision of AS
significantly.
