a The centralized dispatcher tampers with the optimal dispatch solution as well as the multipliers used for LMP-based settlement. This increases the transaction cost of DESs that in general serve as energy consumers by 2221 CNY(5.3%). b In PA, DES 5 pretends the power transmission on lines 5-6 and 5-7 would result in an extra cost and provides its neighbors with wrong but deliberately calculated subproblem solutions. Although the algorithm finally converges and other DESs are in general not influenced, the shadow prices(Lagrangian multipliers) calculated at DES 6-11 are higher and they have to pay more bills. DES 5 benefits from such manipulation behavior. Source data are provided as a Source Data file.
