摘要
PV power generation challenging in solar intermittency irradiance is a main problem in the system operation. Flexible Power Point Tracking (FPPT) algorithm for a PV and battery energy storage system (BESS) for storing surplus power or supplying lacking power are employed for smoothing the power. In contrast to Maximum Power Point Tracking (MPPT) algorithm that required a large BESS to regulate the dc-link voltage, the proposed FPPT can minimize the utilization of BESS. As a results, the operation of FPPT can reduce for the battery sizing while maintaining the benefit of power regulation under 10% of power ramp-rate. This paper presents a comparison of FPPT and without FPPT applying to the PV system to investigate the performance of the proposed control strategy focusing on the utilization of BESS. The real-time simulation HIL is simulated to verify the effectiveness of the system with an irradiance curve profiles. (C) 2021 The Author(s). Published by Elsevier Ltd.
