The proposed RPPT methodology is employed to ensure availability of the required power reserve to support the grid and accordingly facilitate high penetration of PV generation in the grid. Implementing this control methodology does not require any extra hardware. The proposed methodology regulates the average PV power dynamically by periodically operating on and off the maximum power point (MPP) in order to inject a constant desired power into the grid. Tracking a desired power reference implies that the proposed methodology is a form of flexible power point tracking (FPPT). However, unlike a traditional FPPT, the proposed methodology also provides updated information of the available maximum PV power. Hence, the RPPT fulfills both FPPT and maximum power point tracking (MPPT) functionalities simultaneously. The proposed methodology extracts the MPP information and uses this information to calculate and regulate the amount of PV reserve power. One of the main advantages of the proposed algorithm is its applicability under partial shading conditions. Its effectiveness is demonstrated by experimental results under changing solar irradiance, grid frequency deviation, and partial shading conditions.13enginfo:eu-repo/semantics/restrictedAccessjournal article10.1109/TPEL.2023.3240186Flexible power controlgrid supportmaximum power point (MPP)partial shadingphotovoltaic (PV) plantpower reservereserve power point tracking (RPPT)Electrical and Electronic EngineeringSDG 7 - Affordable and Clean Energyhttp://www.scopus.com/inward/record.url?scp=85148458514&partnerID=8YFLogxK
