| 摘 要： | 最大功率跟踪技术被广泛的应用于光伏发电系统,从而使光伏阵列在阳光的照射下发出最大功率。变步长电导增量法因为易于应用且跟踪精度较高而被广泛采用,然而传统的变步长电导增量法在响应时间和功率振荡方面还存在一定的缺陷,本文提出了一种新颖的短路电流法与变步长电导增量法结合的算法,实验结果表明,采用新算法的光伏发电系统的稳态特征和暂态特性都表现优异。

| Abstract: | Maximum power point tracking (MPPT) techniques are widely applied in photovoltaic (PV) systems to make PV array generate peak power which depends on solar irradiation. The variable step size incremental conductance (INC) method is widely employed due to easy implementation and high tracking accuracy. Nevertheless, there are drawbacks in conventional variable step size INC method between time response and power oscillation. A novel short-current combined with variable step size INC method is introduced, experimental results show that the PV generation system has good steady state and transient characteristics with the proposed MPPT control method. |
