According to the International Energy Agency (IEA) report, nearly half of #photovoltaic generators (PVGs) in 2022 have been installed in residential and commercial sectors. Thus, controlling low-voltage #microgrid with such resources in #islanded operation becomes more critical. Although there are several active power curtailment-based #overvoltage controllers, they lack analytical expressions. To ensure accurate power-sharing of multiple PVGs, those methods rely on the support of other primary/secondary/tertiary schemes. To cover such concerns/issues, I am pleased to share our recent publication, "Analytical Overvoltage and Power-Sharing Control Method for Photovooltaic-based Low-voltage Islanded Microgrids" in the IEEE Access journal. The method exploits the series resistance of the single-diode #pvmodule model to define its voltage shift in terms of overvoltage level. Through real-time simulations, the authors of the Delft University of Technology and Jose de Jesus Chavez Muro have shown that the proposed methodology benefits from fast and accurate overvoltage control and power-sharing, a straightforward and communication-free structure, and scalability features without relying on other microgrid facilities. The paper is now online and accessible through the following link. Enjoy reading 🙂
