Abstract

Both photovoltaic (PV) and wind energy is renewable energy that has intermittent power generation and implication for poor power stability. The multi-input DC-DC converter is one of the proven solutions that can be applied to multi-generation systems. In this research, simulations will be carried out to evaluate the performance of multi-input DC-DC converters with perturb and observe MPPT algorithm in off-grid hybrid PV-Wind with battery and supercapacitor energy storage based on solar irradiance intermittencies conditions. From the results, it was found that a multi-input DC-DC converter can rapidly lower ripple voltage on the load side from 12% to 1 - 2% in consequence of intermittent irradiancy even without the implementation of the algorithm on wind turbine output. Also, overshoot and undershoot of the system can be absorbed by the supercapacitor and stored effectively by the battery so that power losses can be reduced. Therefore, the multi-input converter with the proposed Perturb and Observe algorithm can be used as one of the solution concepts for hybrid renewable energy electrical systems.

基于多输入DC-DC变换器的光伏-风能混合存储系统电源管理

光伏和风能都是可再生能源，具有间歇性发电和电力稳定性差的问题。多输入DC-DC变换器是一种成熟的解决方案，可以应用于多代系统。在本研究中，将通过仿真来评估具有摄动的多输入DC-DC变换器的性能，并观察基于太阳辐照度间歇性条件下电池和超级电容器离网混合PV-Wind储能中的MPPT算法。结果表明，多输入DC-DC变换器即使不对风电机组输出实施该算法，也能将负载侧受间歇性辐射影响的纹波电压从12%快速降低到1 ~ 2%。此外，系统的超调和过调可以被超级电容器吸收，并被电池有效地存储，从而减少功率损失。因此，采用Perturb和Observe算法的多输入变换器可以作为混合可再生能源电力系统的解决方案之一。
