Benchmarking of Constant Power Generation Strategies for Single-Phase Grid-Connected Photovoltaic Systems

Abstract: With a still increase of grid-connected Photovoltaic (PV) systems, challenges have been imposed on the grid due to the continuous injection of a large amount of fluctuating PV power, like overloading the grid infrastructure (e.g., transformers) during peak power production periods. Hence, advanced active power control methods are required. As a cost-effective solution to avoid overloading, a Constant Power Generation (CPG) control scheme by limiting the feed-in power has been introduced into the currently acti… Show more

“…2) at the cost of increased power losses (because of power variations) due to the high dP pv /dv pv in that region [6]. Moreover, the PV system may go into instability in that case [34]. Hence, in this paper, the AAPC operating point is regulated at the left-side of the MPP, which is also enabled by the double-stage configuration (i.e., Fig.…”

“…Once the available power P avai is estimated, the slave PV string has to regulate its output power in order to provide the total extracted power (from both PV strings) P pv according to (1). As discussed in [8], [13], the output power of the PV string can be regulated below the MPP using the CPG strategy. From the Power-Voltage (P-V) characteristic of the PV arrays in Fig.…”
