Implementation and Analysis of Grid Support Function for a Smart Inverter-by Seon-Haeng Lee- Aju National University Graduate School Department of Electronic Engineering

Implementation and Analysis of Grid Support Function for a Smart Inverter Advisor: Kyo-Beom Lee Submitted as a Master's Thesis in Engineering February 2022 Aju National University Graduate School Department of Electronic Engineering by  Seon-Haeng Lee 

Abstract Sun-Hang Lee Electrical and Computer Engineering Graduate School Ajou University This thesis implements and analyzes a grid support function for a smart inverter. Due to environmental and air pollution issues, the installation of distributed power using renewable energy has been increased. However, various problems arise when power converters with various output characteristics are connected to the system. Therefore, it is necessary to control the output of the inverter according to the voltage and frequency of the grid. This is called a grid support function which is mandatory to install the function in some countries. The inverter equipped with a grid support function is called the smart inverter. In order to utilize various functions, the smart inverter consists of three boards. First, the main control is a DSP board which is equipped with DSP. The main control system is required a digital processor for fast and accurate control. Also, it is necessary to share information with communication equipment. The second is a breaker control board for connection between the grid and distributed power output. Finally, a sensing board that receives various analog information including voltage and current sensors is required. The grid support function for the smart inverter is implemented and analyzed through simulation and experimental results.

ABSTRACT This paper proposes and analyzes a distributed DC-voltage-based grid-forming control method for a bidirectional interlinking AC/DC converter to address operational challenges in grid-connected DC Local Grids under weak grid conditions. The proposed method adjusts the DC voltage reference based on AC active power output to perform DC Voltage Droop control while integrating a synchronization controller designed through small-signal modeling to enhance stability. To mitigate Synchronous Oscillation (SO) issues caused by the coupling of DC Voltage Droop and grid-forming control, a Notch Filter was introduced. The proposed method was validated through PLECS and PSCAD simulations, demonstrating stable voltage control and power sharing under both strong (SCR=5) and weak (SCR=2) grid conditions. Compared to conventional Grid-Following control, the proposed approach offers improved stability in weak grids while ensuring proper power sharing, enhancing the reliability and flexibility of DC Local Grids.
