Method for managing peak shaving in large scale battery energy storage system

摘要

The present invention relates to a peak shaving operating method of a large capacity battery energy storage system. A method of operating peak shaving in a large capacity battery energy storage system according to the present invention comprises the steps of: receiving 1-day load data and SMP (system marginal prices) information secured in power system operation; A step of rearranging the first SMP information and the load data of the previous long period at the end of the last time period of the next long period in order to maintain the entire charge / discharge scheduling interval based on the SMP information, ; And performing charge / discharge scheduling optimized at a corresponding real-time operation time using an SMP shaving algorithm based on the relocated input data. According to the present invention, when a large-capacity battery energy storage system for storing over-produced energy is installed and operated, SMP shaving, which is a kind of long-term control, is applied in real time, Can be minimized to maximize the economic gain.
