SUN Kai, LIU Guangyu. MPPT control strategy for PV generation system based on improved PSO algorithm[J]. 2021, 40(1): 49-52. DOI: 10.13873/J.1000-9787(2021)01-0049-04.
The photovoltaic(PV) power generation system operates under local shadow conditions.The PV curve of the PV power generation system presents multiple peaks.In order to ensure that the PV power generation system can work at the maximum power point
a control strategy for improving the maximum power point tracking(MPPT)of the particle swarm optimization(PSO) algorithm is proposed.The improved algorithm adopts nonlinear adaptive learning factor and acceleration factor and adopts random inertia weight.Simulation experiment and the real experiment are carried out to verify that the proposed algorithm has a faster convergence speed in the MPPT control of the PV power generation system
and has higher precision and smaller search oscillation.
