摘要：

This paper presents the effectiveness of the basic Active Power Curtailment (APC), also known as Constant Power Generation (CPG) or Power Feed-in Control (PFIC), of a 6.3 kW grid-connected photovoltaic (PV) system in the voltage enhancement at the point of connection through the real-world on-site testing results. The basic APC is able to limit the range of voltage fluctuation at the point of connection with a negligible loss of energy production. In addition, the paper proposed an analysis using complex-power-flow theory in the situation of short-distance connection between PV system and grid feed-in point. It provided an effective view of observing and understanding the changing trends between active power and grid voltage at the point of connection. Discussions on the agreement and discrepancies between the proposed analysis and the real measurement results also present.
