The invention provides a photovoltaic power fluctuation smoothing method based on a self-adaptive revolving door algorithm, which belongs to the technical field of electric power systems and comprises the following steps: acquiring actual photovoltaic power, compressing the actual photovoltaic power by using an initial door width through the revolving door algorithm, calculating a compression error and a compression rate, and calculating the actual photovoltaic power fluctuation. The door width of the revolving door algorithm is adjusted based on the compression error and the compression rate, and the optimal door width is obtained; compressing the actual photovoltaic power by using the optimal door width through a revolving door algorithm, and extracting and processing photovoltaic power characteristic data points to obtain a photovoltaic characteristic curve; and obtaining photovoltaic grid-connected instruction power, distributing the power deviation between the photovoltaic characteristic curve and the ph
