New energy power supply output fluctuation suppression cost change index prediction method

The invention designs a new energy power supply output fluctuation suppression cost change index prediction method. The method comprises the following steps: firstly, defining a new energy power supply output fluctuation suppression cost change index at a tn moment; measuring real-time state data of the battery energy storage equipment and the new energy power supply, establishing a real-time state data time sequence, and performing normalization processing on the real-time state data time sequence; by calculating influence factors corresponding to moments of n fixed time intervals and various data of the moments of the n fixed time intervals, predicting normalized values of the various data of the next moment; and calculating a predicted value of the new energy power supply output fluctuation suppression cost change index at the next time tn + 1 in the future, thereby judging the new energy power supply output fluctuation suppression cost change condition at the next time, and reasonably adjusting the output
