dc.description.abstract | HCPV system is currently the most promising solar power systems, the use of large-scale concentrator module will focus sunlight and exposure on the solar cell, so can reduce the solar cell area, reduce electricity costs, and because of its high efficiency solar cells and a wide range of focus, can increase generating capacity, but the relative, but also because the focus mode enables sensitive to the sun incident angle of deviation, when the incident light deviation exceeds the tolerance range, generating capacity will be greatly attenuated.
Therefore, this study will be the short-circuit current disturbance mixed trajectory tracking method, first locate the sun trajectory, then short-circuit current as a perturbation, while getting the largest short-circuit current, the position of the anchor point and back trajectory error compensation formula and this law does allow aging bodies, institutions and other issues error and positioning error does not affect the HCPV system, but also to get the best output power. | en_US |
