In industrial parks

the load consumption is large and load density pretty high. Research on the electricity purchase mechanism in industrial parks would play an important role in the power system reform in China. An agent mechanism for electricity purchase within the electricity selling market is proposed for industrial parks. Agent

as an emerging market subject

purchases electricity from power plants for users. To make use of the peak-load-staggered effect among users

load curves more friendly for power plants can be generated and consequently lower electricity prices. An objective method is provided for analyzing the profit making space of the agents. Meanwhile

an agent mechanism is designed which is able to satisfy the incentive-compatible principle and the information publishing requirement. The agent mechanism proposed is able to effectively activate the electricity market. The mechanism

which motivates the users to participate

will lower the users’ electricity purchase cost and serve as an important reference for the electricity market reform in China.
