An Adaptive Control Scheme for Flexible Power Point Tracking in Photovoltaic Systems

Abstract: One of the major concerns associated with the increasing penetration of grid-connected photovoltaic (PV) power plants is the operational challenges (e.g., overloading and overvoltage), imposed due to the variability of PV power generation. A flexible power point tracking (FPPT), which can limit the PV output power to a specific value, has thus been defined in grid-connection regulations to tackle some of the integration challenging issues. However, the conventional FPPT algorithm based on the perturb and obser… Show more

“…Among modern grid codes, constant power regulation is considered the most common technique alongside the maximum power point tracking (MPPT) operation [4]. For low power scale PV application, it is important to extract the maximum available power from the PV source at various atmospheric conditions, which is known as MPPT [5]. However, at high power levels, the MPPT operation is allowed if the PV power is lower than a certain threshold.…”
