To maximize conversion efficiency,photovoltaic(PV)systems generally operate in the maximum power point tracking(MPPT)mode.However,due to the increasing penetra-tion level of PV systems,there is a need for more developed control functions in terms of frequency support services and voltage control to maintain the reliability and stability of the power grid.Therefore,flexible active power control is a manda-tory task for grid-connected PV systems to meet part of the grid requirements.Hence,a significant number of flexible pow-er point tracking(FPPT)algorithms have been introduced in the existing literature.The purpose of such algorithms is to real-ize a cost-effective method to provide grid support functional-ities while minimizing the reliance on energy storage systems.This paper provides a comprehensive overview of grid support functionalities that can be obtained with the FPPT control of PV systems such as frequency support and volt-var control.Each of these grid support functionalities necessitates PV sys-tems to operate under one of the three control strategies,which can be provided with FPPT algorithms.The three control strate-gies are classified as:① constant power generation control(CP-GC),② power reserve control(PRC),and ③ power ramp rate control(PRRC).A detailed discussion on available FPPT algo-rithms for each control strategy is also provided.This paper can serve as a comprehensive review of the state-of-the-art FPPT algorithms that can equip PV systems with various grid support functionalities.
