　　混合光伏-风力系统由太阳能光伏,风力发电机组,逆变器,电池和其他组件组合而成。一旦电力资源(风能和太阳能)充足,所产生的多余电能需由电池消纳,直至电池完全充电。电池作为电能储存单元是任何隔离式可再生能源系统中最关键的部分。电池管理直接决定系统运行的效率和优化程度。因此,当可再生能源(太阳能和风能)不能满足负载需求时,电池可以作为电源供电,直到电池能量耗尽。混合太阳能PV风微电网框架的运行依赖于单个组件。本文所建模型的混合动力系统由于其互补性而成为风光互补系统。该系统主要由太阳能和风力发电机组,蓄电池和电力电子转换器组成。当太阳能和风力发电机组的输出超过负荷需求时,多余的能量储存在电池中,以便在发电量不满足负荷需求时使用。因此,电池充放电控制对于提高系统效率和降低成本具有十分重要的意义。建模系统以约3KW的风力和1KW的太阳能作为可再生能源。为了能够从每个部件获得最佳输出,首先我们对单个部件进行建模,通过评估它们的组合,以满足所需的可靠性。本研究提出了一种基于模糊逻辑控制器的智能电池能量管理系统,选择三角隶属函数来配置模糊逻辑控制器。这种基于控制器的电池管理框架专为有效的电力使用而设计。...
