Analysis of Hosting Capacity and Power Quality in a Distribution Line with a Photovoltaic Installation: A Case Study

Brief Introduction

The paper explores the issues related to overloading low voltage distribution lines and its effects on power quality and system stability. The study primarily investigates the integration of photovoltaic(PV) systems into low voltage feeders, considering both commercial and residential users. It aims to assess the existing and future potential of these distribution lines to accommodate PV installations, particularly focusing on the shift of residential consumers towards becoming prosumers. Additionally, the research emphasizes the consequences of exceeding the distribution line's capacity on power quality and underscores the necessity of adhering to power quality regulations stipulated by grid codes and standards.


Commercial PV inverter simulation using DSIM

To investigate potential impacts of high energy consumption or large-scale integration of PV systems at the aggregated user level, considering high-energy-consuming commercial buildings equipped with large PV systems, this paper uses DSIM to simulate commercial PV inverter and analyze the system's performance. The simulation converts one real-life hour into one simulated second. Moreover, the commercial PV setup includes a power-controlled load in parallel.

According to the paper, “these simulations are conducted using the DSIM software which is capable of simulating simple topologies or large and complex systems with astounding speed and accuracy.”
