METHOD FOR QUICK CALCULATION OF ACTIVE POWER REFERENCE VALUE OF GRID-CONNECTED PHOTOVOLTAIC POWER STATION

WIPO Patent Application WO/2018/176902

A1

A method for quick calculation of an active power reference value of a grid-connected photovoltaic power station, capable of making a quick calculation of a reference power value meeting a requirement of a grid-connected photovoltaic power station while maintaining output power characteristics of a photovoltaic power station, such that the reference power value serves as the basis on which an energy storage device stores/supplies power, thereby realizing a smooth power output from a grid-connected photovoltaic power station. A reconstructed photovoltaic power signal obtained by implementing an improved empirical mode decomposition method, novel wavelet denoising, and principal component analysis can effectively reduce fluctuation of an original signal, thereby inhibiting power fluctuation, and realizing a smooth power output of a grid-connected photovoltaic power station. The present invention quickly acquires a combination of the three preceding components by means of on-line collection, chronological segmentation and principal component analysis, thereby effectively increasing a calculation speed.
