Abstract

There are various types of renewable energy sources worldwide, including Photovoltaic (PV) systems. PV systems have witnessed significant growth in recent years to meet the demands of economic, technological, and environmental advancements. However, as Distributed Energy Resources (DER) penetration increases, active distribution networks face numerous challenges, making it increasingly complex for distribution system operators to effectively manage and design their networks. One of the key challenges involves maintaining voltage profiles within specified limits to avoid load reduction or decreased renewable energy production. To address this issue, Photovoltaic (PV) inverter based on reactive power control schemes offer a potential solution. This paper focuses on the implementation of reactive power) control using both Model Predictive Controller (MPC) and PI controls. The objective is to maintain the voltage profile within prescribed limits at the bus connected to the PV system in a low-voltage distribution network. The study considers two scenarios: over-voltage and under-voltage, demonstrating the enhancement of Hosting Capacity (HC) through reactive power control. MATLAB SIMULINK is employed to analyze the effects and quantify the improvements. The findings of this research highlight the significant support provided by smart inverter reactive power control in increasing the integration of PV solar systems into the grid, thereby enhancing the HC of the system.
