[0038] Below in conjunction with embodiment, the present invention is described in further detail:
[0039] A photovoltaic cell parameter identification method based on the improved Harris Eagle optimization algorithm, comprising the following steps:
[0040] a. According to the basic mathematical model of the photovoltaic cell, construct the engineering model of the photovoltaic cell, construct the fitness function based on the engineering model of the photovoltaic cell, collect and process the output current and voltage data of the photovoltaic cell, and then quickly solve it;
[0041] b. Introduce a flexible decreasing strategy, expand the global search range at the beginning of the iteration, prolong the local search time at the later stage of the iteration, and improve the balance between the global search and the local search;
[0042] c. The golden sine method is introduced, which increases the diversity of the population, reduces the possibility of the algorithm fallin...
