Abstract
The present invention provides an energy management method of a multi-type battery energy storage power station considering charge and discharge rates, that includes: reading related data of the battery energy storage power station; calculating charge or discharge rate characteristic values of battery energy storage machine sets; calculating initial power command values of the battery energy storage machine sets; judging whether the initial power command values of the battery energy storage machine sets exceed the maximum allowable charge or discharge power of the machine sets in real time, if more than, online correcting and re-calculating the initial power command values of the battery energy storage machine sets; otherwise, setting the initial power command values of the energy storage machine sets as the power command values thereof; and summarizing the power command values of the battery energy storage machine sets, and outputting the same. With the reasonable control of the charge and discharge rates of the energy storage machines sets as target, the energy management method of the present invention is used for carrying out power coordinated control and energy management in the energy storage power station, and considering the service lives of energy storage batteries in the control strategy to achieve the functions of avoiding abuse of the energy storage batteries as much as possible, delaying battery aging and the like.
