| Abstract: | Based on the theory analysis, it established the mathematical model of PV array under partial shading conditions. With simulation, it analyzed the limitations of traditional single channel, single peak MPPT tracking algorithm in partial shading applications, proposed several measures to improve the performance against partial shading of PV arrays. It can be a guidance for simulation analysis and optimized the design of large-scale PV power stations under partial shading conditions. |
