The invention relates to the technical field of
electric power energy storage, in particular to an
energy storage demand analysis method of a high-proportion
new energy power grid, which comprises the following steps of: obtaining a power predicted value and a measured value through a prediction platform to calculate deviation, performing sliding window segmentation, dynamically adjusting length based on volatility to extract variance characteristics, and calculating the
energy storage demand of the high-proportion
new energy power grid; and the center number is optimized through K-means clustering, a
classification result is output, a capacity adjustment value is calculated according to a matching grade adjustment coefficient, time points are extracted and sorted according to a load and output
correlation coefficient, and an energy storage capacity space-
time distribution table is generated. According to the invention, through prediction of deviation sequence sliding window segmentation and variance
feature extraction, dynamic identification of
new energy output fluctuation intensity, construction of a deviation fluctuation and energy storage capacity mapping model, quantification of load and output
coupling intensity, and construction of a multi-dimensional energy storage
correction system, energy storage and source load dynamic matching is realized, and
response sensitivity is improved. The risk of resource mismatching is reduced, the robustness of the
system is enhanced, and the cooperative efficiency of charging and discharging strategies is optimized.
