Implementation of a power supervisory for hybrid power system

ABSTRACT

During the last decades, the use of sustainable energies instead of conventional fuel has been increased due to the global anxiety on environmental and economic problems like climate changes, the limitation of traditional resources, and the increase of electricity consumption. In the present work, design, modeling, and simulation of a Hybrid Power System (HPS), which is united a Wind Turbine System (WTS) with a battery bank, is presented. However, the power operation of the HPS is controlled by a power supervisory in order to reduce energy loss. The supervisory has been implemented in STM32F4 by using the ‘PIL simulation’ technology and tested under different scenarios of climatic conditions. The results indicate that, during a windy climatic condition, the proposed HPS is broadly enough to generate 100% of the required power with 0.005% of LPSP and 99.84% of RF. Whereas, through a moderate wind speed, the HPS reaches 0.675% of LPSP and 66.94% of RF. But, with a low wind speed, the HPS achieves 0.919% of LPSP and 26.10% of RF. Besides, the proposed WTS was broadly sufficient for supplying the needed power, with an empty battery, especially, when the available wind velocity is around 14.3 m/s at least. Furthermore, it illustrates the efficiency of the supervisory control.
