With a passive method, detection of islanding from the utility grid is achieved via AC under/overvoltage and under/overfrequency detection functions. Output overcurrent Due to fault conditions or AC line transient conditions, the maximum current may be exceeded.
The converter performs MPPT and grid connection by means of an ARM Cortex M3-based STM32F103xx microcontroller, which is proven to be well suited for such an application. In fact, the implemented DQ axis control scheme shows excellent regulation of both active and reactive power, as is also required for low power applications in the near future.
A single-phase grid-connected inverter, with unipolar pulse-width modulation, operates from a DC voltage source and is characterized by four modes of operation or states. Two modes take place during the positive load current period and two modes in the negative load current period, as shown in Table 6. Table 6.
Line voltage and frequency detection and anti-islanding The PLL continuously measures the line voltage and frequency in all operating states. If the voltage or frequency exceeds the high or low limits, the inverter ceases to deliver power to the grid. These conditions are also used to implement a passive method for island operation detection.
Table 1. The dual-stage inverter for grid-connected applications includes a DC-DC converter to amplify the voltage and a DC-AC inverter to control the current injected into the grid. Figure 3. The DC-DC converter is depicted in Figure 3 together with the DC-AC converter and LCL filter.
Every algorithm for grid-connected inverter operation is based on the estimation or direct measurement of grid-voltage frequency and phase angle. Both parameters are fundamental for correct operation and special care must be taken in their detection to avoid the influence of any external noise.
