Analysis of Key Technologies in BIPV Micro-grid System

对光伏建筑一体化微网系统的发展现状进行了分析,提出了其面临的主要关键问题。针对目前所光伏建筑微网系统控制瓶颈问题,提出了分别采用切换系统理论、容错控制算法和鲁棒控制理论,研究其并网与孤岛状态的平滑切换、安全保护、电能质量控制及能量优化控制问题。所采用的控制算法与传统方法相比具有精确度高、可靠性强、效率高等优点,将进一步推动光伏建筑微网系统的应用和发展。

The development status of BIPV micro-grid system is reviewed, and the main scientific issues are presented. Based on the control bottleneck for current BIPV micro-grid system, the switching system theory, the fault tolerant control algorithms and the robust control theory are introduced to study the smooth switching of grid and island states, security protection, power quality control and energy optimization control. The control algorithms introduced in this paper are more accurate, more reliable and more efficient than the traditional ones, which will promote the BIPV micro-grid system applications and development.
