Research on suppressing false information in micro-grid transactions with Stackelberg game based on dynamic integrity factor
In order to suppress the false information existing in the interactive information between microgrid(MG)and microgrid cluster operator(MGCO),a trading mechanism with the Stackelberg game is proposed,and a dynamic integrity factor is used to consider the honesty behavior of the MG.Firstly,a reward and punishment mechanism based on the reported electricity quantity and the actual trading quantity is established.Transaction price can be adjusted by credit factor.Secondly,a Stackelberg game model with MGCO as leader and MGs as followers is developed.The upper level minimizes fluctuation of power for microgrid cluster,where a contract mechanism of transaction is established to adjust basic transaction prices within the cluster.In the lower level,the cost of MG operation is minimized.Each MG acts as the follower responding to the day-ahead trading price and decides the electricity of exchange power with MGCO.Finally,the study prove that the presented transaction mechanism effectively suppresses the false information.
