Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a method and system for calculating power generation of a water-cooled photovoltaic-photothermal integrated power generation system. Background technique [0002] The distributed photovoltaic power generation system for small users such as urban residents and large user groups such as commercial buildings, communities, and industrial areas is such a system with random and fuzzy uncertain events or parameters with complex relationships and interactions. Small new energy users such as urban residents with distributed photovoltaic power generation systems and large new energy user groups such as commercial buildings, communities, and industrial areas, under the influence of various uncertain random and fuzzy events or parameters, their daily power generation will change. more random and fuzzy. [0003] In the past, the daily power generation of distributed photovoltaic power ...
