摘要

针对负载需求和风的突变，提出了一种基于比例加积分(PI)控制器的孤立自主混合分布式发电系统的频率调节方法。所开发的混合动力系统包括风力发电机(WTG)、微型涡轮发电机(MTG)、燃料电池(FC)、水电解槽(AE)以及电池储能系统(BESS)等储能装置。进一步将超级电容器(UC)作为替代储能元件纳入系统，以获得更好的性能。由水电解槽产生的氢用作燃料电池的燃料。本文的仿真结果主要集中在变风力、阶跃负荷变化和变负荷下的频率响应。

Performance study of isolated hybrid power system with multiple generation and energy storage units

This paper presents proportional-plus-integral (PI) controller based frequency regulation of isolated autonomous hybrid distributed generation system for sudden variation in load demand and wind. The developed hybrid system comprises of wind turbine generator (WTG), micro-turbine generator (MTG), fuel cell (FC), an aqua electrolyzer (AE) along with the energy storage device such as battery energy storage system (BESS). Further ultracapacitor (UC) as an alternative energy storage element is incorporated into the system for better performance. The generated hydrogen by an aqua electrolyzer is used as fuel for a fuel cell. The simulation results reported in the paper focused on frequency response for variable wind power, step load change and variable load.
