Automatic Control Algorithm for Improved Stability and Charge-Discharge Efficiency

摘要

The estimated excess power generation (Eo) and the control interval margin (Cb) are obtained based on the estimated power generation (Ef) based on the previous day power generation (Pf), and the output value (Ct) obtained for each control section using the control interval margin (Cb) ), an algorithm of an energy management system is disclosed in which charging is distributed and distributed to the ESS from the start time of the REC charging to the expiration time. According to the present invention, it is possible to minimize the downtime with high fire frequency by performing discharge immediately after buffering. In addition, the efficiency of PCS equipment is higher when the operation is reduced between 70 and 80% than when the operation is performed at the rated (100%), but the present invention can reduce the operation of the PCS, thereby improving power conversion efficiency. In addition, in the case of a battery, the higher the c-rate (battery charge/discharge rate) (quick charge), the shorter the lifespan, and the PCS reduction operation of the present invention can lower the battery charging speed, which also helps with battery life.
