[Abstract]:Photovoltaic power generation is one of the important components of new energy development and utilization, and has a good development prospect.Because of its inherent advantages, researchers all over the world pay attention to it, especially for remote areas of power generation systems, independent photovoltaic power generation system compared with other generation systems have unparalleled advantages.In the design of modern independent photovoltaic power generation system, optimization design has become an indispensable important link.This paper mainly studies the optimization design of independent photovoltaic power generation system.In this paper, the hardware design and the design and implementation of the software for the independent photovoltaic power generation system are studied.First of all, on the basis of comparing and analyzing the advantages and disadvantages of topology structure of common independent photovoltaic power generation system, the whole design scheme of independent photovoltaic system is discussed in this paper.According to the actual project-the need of independent photovoltaic power generation system in Ali area of Tibet, the design of the existing minimum system type off-grid photovoltaic power generation system is optimized and improved. Secondly,This paper analyzes, designs and implements the modules of the independent photovoltaic power generation system from the aspects of software and hardware, and introduces the whole independent photovoltaic power generation system.Finally, the test results of various main functions of the test prototype are described, and a feasible plan for further improving the overall performance of the system is put forward.Through theoretical analysis, simulation and test, the system runs well, the optimized system is reasonable and feasible, the whole system is proved to be stable and reliable by experiment, and can be used as an independent photovoltaic system prototype, which achieves the desired results.The design method of the independent photovoltaic system proposed in this paper, combined with the actual environment and equipment characteristics, optimizes the whole system, and improves the stability and economy of the whole system.It has certain theoretical and practical significance for the application and research of independent photovoltaic system.
