Nowadays, we need to use renewable energy sources to generate power and support the growing demand for electricity and also to protect the environment from carbon gas. However, wind power is one of the alternatives for generating electricity. For this reason, our paper aims to achieve a functional, structural, and behavior description of a wind power systems using the systems modeling language SysML. In this paper, we start with presentation of wind power system. Next, we describe the systems modeling language SysML. Subsequently, we present the modeling results of wind power system based on SysML diagrams. Finally, concludes this paper with some prospects.
