Abstract

A Battery Energy Storage System (BESS) is one of the solutions being proposed to improve the performance and reliability of various power system applications. Indeed, BESS is a reliable resource to provide energy, and to increase the reliability and flexibility of the renewable energy dispatch. Wind energy has the largest contribution among renewable energy resources and its control has become a research focus in the power systems area. This paper introduces a novel BESS control, which depends on a Fuzzy-Logic based Frequency Regulation (FL-FR) for wind farms composed of 5 Wind Turbine Generators (WTGs) augmented with BESS. Moreover, rotor speed of the deloaded WTG is optimized to extract more rotational kinetic energy. WTG can ensure sufficient generation reserve using deloaded operation, which can be used during depressed frequency conditions. The performance of the studied system is proved through simulation in the MATLAB/Simulink environment.
风力/电池独立微电网的一次频率控制
电池储能系统(BESS)是提高各种电力系统应用性能和可靠性的解决方案之一。事实上,BESS是提供能源的可靠资源,并增加可再生能源调度的可靠性和灵活性。风能是可再生能源中贡献最大的能源,其控制已成为电力系统领域的研究热点。本文介绍了一种基于模糊逻辑的频率调节(FL-FR)的新型BESS控制方法,该方法适用于由5台风力发电机组(WTGs)组成的风电场。此外,还对减载WTG的转子转速进行了优化,以提取更多的旋转动能。WTG可以通过减载运行来保证足够的发电储备,可以在低频率条件下使用。通过MATLAB/Simulink环境下的仿真验证了所研究系统的性能。
