Abstract
(EN) Disclosed is an optimization design method for a photovoltaic system by taking system benefit optimization as a target. The optimization design method comprises: how to select the type of a photovoltaic module, the form of an inverter, the arrangement means of the module, the tracking form of a support and a module-inverter capacity ratio value to achieve the benefit optimization of a photovoltaic system, wherein the model selection of each apparatus and parameter of the system is obtained by means of optimization iteration by taking an inclination angle as an iteration variable and taking a system benefit as an optimization design target under all the above combination means. The method has the advantages of the benefit of the photovoltaic system being taken as the optimization design target, and that the influences of the type of the system module, the form of the inverter, the module arrangement and tracking form, the capacity ratio, the land cost, the power station operation and maintenance cost, etc. on the benefit of the photovoltaic system are comprehensively considered, thereby acquiring the optimal photovoltaic system design solution.
