研究目的
Investigating the effectiveness of a new control method for grid-connected PWM inverters to reduce output current harmonic distortion and improve power quality in micro-grids.
研究成果
The proposed control method significantly improves the power quality in micro-grids by reducing the THD of the interface inverter for DGs and the grid current. It can be easily integrated into the DG control system without additional hardware, making it a cost-effective solution for enhancing power quality.
研究不足
The study is based on simulation results, and real-world application may present additional challenges not accounted for in the simulation. The effectiveness of the control method under varying grid conditions and with different types of non-linear loads needs further investigation.
1：Experimental Design and Method Selection:
The study employs an advanced synchronous reference frame method (ASRF) for controlling grid-connected inverters to reduce harmonic distortion.
2：Sample Selection and Data Sources:
The system includes photovoltaic (PV) arrays, fuel cells (FC), micro-turbines (MT), and wind turbines (WT) connected to the grid via inverters.
3：List of Experimental Equipment and Materials:
Grid-connected PWM inverters, PV arrays, FC, MT, WT, and non-linear loads.
4：Experimental Procedures and Operational Workflow:
The proposed control method is applied to the PV inverter, and its performance is compared with conventional methods through simulation.
5：Data Analysis Methods:
The effectiveness of the control method is evaluated based on the reduction of total harmonic distortion (THD) in the system.
