Abstract:

According to the anisotropic Hay's model of the sky-diffuse radiation and the calculation of solar total radiation,the calculation of solar radiation of tilted surface with various tilt angle and azimuth angle can be got.Taking into account the tilt angle and the azimuth angle,we firstly get the cells with benefits evaluation,and then match the inverter by greedy algorithm.But only the local optimum solution can be found by this method.For the solution to be more precise,a multi-step optimization algorithm is constructed to make the inverter matched based on the cost-benefit goal programming model and the greedy algorithm,by which the optimum combination of solar photovoltaic cells in the overhead conditions under the laying of the program can eventually be obtained,effectively improving the work efficiency of the battery pack.
