METHOD FOR ESTIMATING PHOTOVOLTAIC POWER GENERATION OUTPUT WITH CONSIDERATION OF INFLUENCE OF SHADE

摘要

PROBLEM TO BE SOLVED: To provide a method for estimating a photovoltaic power generation output with consideration of influence of shade.SOLUTION: Division is performed under previous conditions of solar altitude, a solar azimuth angle, and a solar radiation intensity. A power generation amount estimation parameter of a power generation amount estimation model is calculated in each data measurement time 1 by the solar altitude, the solar azimuth angle, the solar radiation intensity 2, an outdoor temperature 3, and a power generation amount 4 at the measurement, is distributed into each division, and repeats the above operation for a constant period. Thus, the power generation amount estimation parameter is learned. A power generation amount estimation parameter 6 in each division is previously formed, and an estimation power generation amount is calculated by using a specified solar altitude, a solar angle, and the power generation amount estimation parameter 6 of the solar radiation intensity divided in each division on the basis of a data measurement time 8, the measured solar radiation intensity 9 and the outdoor temperature 10.SELECTED DRAWING: Figure 1
