Finding the model parameters of photovoltaic (PV) modules by a novel modified differential evolution algorithm

【摘要】：We use the novel modified differential evolution (NMDE) algorithm algorithm to determine the model parameters of photovoltaic modules in this paper. NMDE is a new proposed DE variation, and each solution has its own scale factor and crossover rate. In detail, for each solution vector, its own scale factor and crossover rate are adaptively adjusted in terms of the corresponding values of all successful solutions. In addition, if it is continuously at a standstill during a fixed number of iterations SP (Stagnation period), its scale factor and crossover rate will be randomly generated according to normal distribution. Experimental results show that NMDE is an effective method on finding suitable parameters of PV model.
