The invention discloses a method and a system for apportioning and evaluating loss in a shared control area in a regional power grid accident, which can guide and restrain the compensation and evaluation in each shared control area when the regional power grid fails. The technical scheme is that the method comprises the following steps of: (1) judging whether a frequency fault occurs or not; (2) judging whether an electric loss exists outside a relevant area or not; (3) confirming an error and adding the error in a current error list; (4) scanning the current error list and calculating apportionment compensation to loss power in each shared control area; (5) calculating a control performance assessment standard; and (6) transmitting the data for compensating power to each party. The method and the system of the invention can be applied to an electric power system.
