Method, device and equipment for determining generating capacity gain of photovoltaic power station and medium

Abstract

The invention discloses a photovoltaic power station generating capacity gain determination method and device, equipment and a medium, and belongs to the technical field of photovoltaic power generation, and the method comprises the steps: determining the dust influence degree of a target detection unit in a photovoltaic power station in any detection day based on a # imgabs0 # clustering algorithm and a similar day theory, and obtaining the target dust influence degree; according to the target dust influence degree, the dust influence degree of a target detection area in the photovoltaic power station on the target evaluation day and the dust influence degree when the photovoltaic power station is not cleaned are determined, and the actual dust influence degree and the original dust influence degree are obtained; and determining the generating capacity gain of the target detection area in the photovoltaic power station in the evaluation period according to the actual generating capacity, the actual dust influence degree and the original dust influence degree of the target detection area in the target evaluation day. By means of the method, the purpose of accurately evaluating the generating capacity gain of the photovoltaic power station after cleaning is completed can be achieved.
