On the design of standard application function blocks for microgrid automation

Development of Application Function Blocks for Power-Hardware-in-the-Loop Testing of Grid-Connected Inverters

“…A good way to do this is by using application function blocks (AFBs). AFBs are modelbased and can be developed as a standard library component, thus achieving satisfactory reusability and reconfigurability for various platforms [9]. Because of the software flexibility of the PHIL simulation, appropriate functions can be easily implemented in the digital real-time simulator (DRTS) to preprocess the reference signal before sending it to the power amplifier [7].…”
