代码说明:

界面追踪方法——VOSET(coupled Volume-of-Fluid and Level Set method)结合了VOF和Level Set两种方法的优点,克服了这两种方法的缺点。VOSET方法采用VOF方法捕捉两相间的界面,保持了两相间的质量守恒,克服了Level Set方法质量不守恒的缺点;利用几何计算方法计算界面附近的Level Set函数,从而可以计算出准确的界面曲率和光顺界面附近突变的物理量,克服了VOF方法利用流体体积函数C计算界面曲率误差较大和光顺界面附近突变的物理量效果较差的缺点,因此该方法较VOF和Level Set方法更加精确。

    The model used for creating the reference voltage is shown in Fig. 4. First, photovoltaic output current (Ipv) and output voltage (Vpv) are passed through a first order low pass filter with a magnitude of G = 1 and a time constant of T = 0.01 seconds in order to filter out the high frequency components or harmonics from these signals as shown in Fig. 5 and Fig. 6. The filtered current and voltage signals (Ipv_F and Vpv_F) are then fed into the MPPT control block that uses the Incremental Conductance Tracking Algorithm. An algorithm that is based on the fact the slope of the PV array power curve shown in Fig. 7 is zero at the Maximum Power Point (MPP), positive on the left of the MPP, and negative on the right. The MPP can thus be tracked by comparing the instantaneous conductance (I/V) to the incremental conductance (∆ I/∆ V) [11] as in (1):
