Master-Slave Game Based Optimal Pricing Strategy for Load Aggregator in Day-ahead Electricity Market
A load aggregator (LA) provides load smoothing services to the power grid and obtains revenue by integrating user-side resources through demand response. Therefore
the response pricing strategy of LA and users’ response preference will affect the accuracy of users’ response directly
and then affect the revenue of LA. The load resources involved in the demand response are regarded as generalized demand side resources (GDSRs)
and demand response mechanism based on price incentives is proposed. Then
a user utility model considering user preference and an aggregator revenue model are constructed. Furthermore
aiming at maximizing the interests of both users and LA
a master-slave game model is established
which is calculated to obtain the optimal compensation pricing strategy of LA and analyze the users’ electricity elasticity to optimize users’ response. Finally
the data of American PJM market are used for simulation. The simulation results verify that the optimal pricing strategy based on the master-slave game can reduce users’ comprehensive cost effectively through full consideration of the differences in users’ response preference
and increase the market revenue of LA by smoothing the load fluctuation.
