Abstract:
The widespread deployment of photovoltaic (PV) systems in urban areas poses new challenges for integration into the low-voltage grid, operation under variable meteorological conditions, and the impact of local disturbances. Research using Hardware-in-the-Loop (HIL) simulations, especially techniques with physically present controllers (Controller Hardware-in-the Loop - C-HIL), represents a powerful environment for testing and validating power electronics-based converter control strategies in real-world conditions without the risks and costs associated with field experiments. This paper presents the application of C-HIL simulation to analyze and optimize the operation of a home PV system integrated into an urban distribution grid. The conducted case studies address operational scenarios such as rapid changes in solar radiation, load fluctuations, and voltage disturbances, demonstrating the effectiveness of the C-HIL platform for assessing dynamic performance, voltage quality, and stability. The results confirm that C-HIL simulation can provide useful insights for the design of PV systems aimed at the safe and widespread deployment of distributed renewable energy sources in urban networks.
