The invention discloses a photovoltaic power climbing event influence factor correlation analysis method, system and device and a medium, and the method comprises the steps: obtaining a climbing rate of a photovoltaic climbing event and meteorological data corresponding to the climbing event, taking the climbing rate as a mother sequence, taking meteorological influence factors as subsequences, carrying out the gray correlation analysis of the mother sequence and the subsequences, and obtaining a correlation analysis result; obtaining a first correlation degree between each sub-sequence and the photovoltaic power climbing event, calculating a correlation weight between each sub-sequence and the mother sequence based on the first correlation degree and the correlation matrix, and calculating a second correlation degree between each sub-sequence and the photovoltaic power climbing event according to the correlation weight and the correlation matrix; and determining a correlation degree sequence of each factor a
