研究目的
To review issues associated with distributed photovoltaic generation (DPVG) on low voltage (LV) distribution networks (DNs), with an emphasis on grid voltage, and to propose solutions.
研究成果
The paper concludes that APC is more suitable for high R/X ratio LV DNs compared to RPC. For other networks, strategies such as coordinated local APC and RPC can be used to mitigate voltage problems. It emphasizes the need for more efficient and effective solutions to address intermittent DG.
研究不足
The paper is a review and does not present new experimental data. It highlights the need for more efficient and effective solutions to address intermittent DG, as commercially available control equipment does not fully address this issue.
1：Experimental Design and Method Selection:
The paper reviews existing literature on DPVG integration in radial 3φ LV DNs, focusing on voltage rise (VR) and voltage drop (VD) issues. It utilizes mathematical equations and circuit diagrams for VR and VD analysis.
2：Sample Selection and Data Sources:
The study is based on a comprehensive review of current research and literature on DPVG integration, particularly in South Africa.
3：List of Experimental Equipment and Materials:
Not explicitly mentioned.
4：Experimental Procedures and Operational Workflow:
The paper details proposed and commercially available mitigation solutions including active power curtailment (APC), reactive power control (RPC), and droop-based voltage control.
5：Data Analysis Methods:
The analysis is based on mathematical relationships and circuit diagrams for voltage rise and drop analyses.
