Abstract

In order to guarantee a quick and seamless transition among maximum power point tracking using Partial Power Converter (PPC) and Stationary Reference Frame (SRF) methods, an improved power management technique that limits the maximum feed-in capacity of Photovoltaic system has been suggested. Regardless of the irradiance levels, an operational control strategy is constantly maintained for high-performance and steady operation. it regulates overall PV output power to any desired set point, with no instability issues, and makes the PV systems always run on the near half of both the maximum power output According to the evaluation, a better PPC control with high precision, rapid dynamics, and stability improved performance. The converter and control loop are both responsible for overall power management. For the entire system, model-based performance analysis (including power and stability) is performed using MATLAB/SIMULINK

基于DC-DC变换器的光伏系统电网稳定性综合评估

为了保证采用部分功率变换器(PPC)和固定参照系(SRF)方法进行最大功率点跟踪之间的快速无缝过渡，提出了一种限制光伏系统最大馈电容量的改进电源管理技术。无论辐照水平如何，操作控制策略都能持续保持高性能和稳定的运行。它可以将整体PV输出功率调节到任何所需的设定点，不存在不稳定问题，并且使PV系统始终运行在最大功率输出的近一半。根据评估，更好的PPC控制具有高精度，快速动态和稳定性的性能提高。转换器和控制回路都负责整体电源管理。对于整个系统，利用MATLAB/SIMULINK进行了基于模型的性能分析(包括功耗和稳定性)
