The application relates to the technical field of
electrical equipment evaluation, in particular to a multi-dimensional
electrical equipment stability evaluation method and device for
new energy power grid connection, which comprises the following steps: based on a multi-dimensional evaluation
index system, collecting multi-dimensional index data of a target
electrical equipment, performing feature enhancement
processing, and generating processed enhanced features; based on a
grid connection power fluctuation coefficient and an equipment operation stage coefficient of the target electrical equipment, adjusting the weight proportion of each dimension and corresponding indexes in the multi-dimensional index data to obtain dynamic weights; inputting the processed enhanced features and the dynamic weights into an evaluation model combining fuzzy comprehensive evaluation and
Markov chain prediction, performing stability evaluation on the target electrical equipment for
new energy power grid connection, and outputting a stability
evaluation result of the target electrical equipment. Therefore, the problems that in the related art, prospective decision support cannot be provided for
preventive maintenance and
grid connection scheduling, and it is difficult to guarantee the safe and stable operation of the
power grid under high-proportion
new energy access are solved.
