The present invention predicts the accuracy high demand loads that, the technical problem to be solved is through the analysis of the various factors that affect the demand load data with the demand load on the charging and discharging algorithm prediction system of ESS installed in the power suyongga, Based on this and providing a peak time of day energy storage and more through the effective charge and discharge control economics and reliability is enhanced optimal power supply when the system is introduced into the power suyongga to implement charging and discharging algorithm of the energy storage system through the estimate calculated, the electric power fee It is to reduce.
In one example, the target power suyongga demand load data in a recent period of time, climate data, and time and seasonal power data acquisition unit for collecting and processing the pattern data; The data collected extraction part on the data collected at regular time intervals, respectively through, and the extracted data through the multiple regression analysis is applied to the argument estimate the demand load forecast for the future demand load, based on the demand load predicted estimate data estimator for estimating a peak load demand; Data setting unit for setting a demand load reduction target value for the peak load demand estimated by the data estimating portion; Each classified according to the demand load reference range with the data estimating unit is set beforehand the demand load predicted estimate over time, and performing the magnitude comparison between the classification demand load forecast the demand load reduction target value set through the said data set, and each comparison result generation algorithm to generate the charge and discharge of the algorithm ESS each unit in accordance with; And it calculates a charge-discharge estimate of the ESS, and the charging and discharging algorithm prediction of ESS containing portion based on the calculated discharge estimate generation data for generating control data of the ESS according to the charging and discharging algorithm generated by a generator the algorithm It discloses a system.
