The purpose of the present invention is to provide a method and device for operating a power system, and a rechargeable-battery management device, that extract maximum performance from rechargeable batteries and use said batteries evenly while taking into consideration cost and the operation of the batteries. In order to solve said problem, in this method for operating a power system provided with a plurality of rechargeable-battery devices and a plurality of electric generators, the amount of power that a rechargeable battery available during a scheduled time period on a scheduled date will be able to supply is determined, an economic-dispatch calculation including the determined amount of power that the aforementioned rechargeable battery will be able to supply is performed for the power system, and said rechargeable battery is used to supply power during the scheduled time period on the scheduled date.

The invention provides a multi-region power system economic dispatching method and device. The method comprises the steps that each regional power grid dispatching mechanism obtains the basic operation parameters of a regional power grid, and builds a regional power grid economic dispatching model taking the power of a tie line as a parameter variable according to the basic operation parameters ofthe power grid; each regional power grid dispatching mechanism identifies a regional power grid aggregation model according to the regional power grid economic dispatching model and reports the aggregation model to a cross-regional dispatching mechanism; and the cross-regional dispatching mechanism constructs a multi-regional power system economic dispatching simplification model based on the power grid aggregation model of each region, and solves the multi-regional power system economic dispatching simplification model to obtain an economic dispatching result of each region. Therefore, non-iterative coordinated optimization scheduling of the multi-region power system can be realized through a small amount of information interaction, and the scheduling economy and solving efficiency of the multi-region power system are improved.
