The potential of combining biogas and photovoltaic (PV) power plants in hybrid systems in the German distribution grid is analyzed. The focus of the present research is on balancing the intermittent power supply from PV power plants with the controllable power production of combined heat and power (CHP) units of biogas plants within a period of seconds. To achieve an increase of the total energy feed‐in of biogas and PV power plants to the electricity grid, a biogas plant energy management system is described. System parameters, such as the variable feed‐in of PV power plants or power ramps of the start‐up process of controllable biogas plant CHP unit, are described and adapted to the global installed capacity of PV power plant and biogas plants in the German distribution grid.

配电网中光伏电站与沼气厂混合系统的柔性潜力

分析了德国配电网中混合系统中沼气和光伏（PV）发电厂的组合潜力。本研究的重点是在几秒钟内平衡光伏发电厂的间歇电源与沼气厂热电联产（CHP）单元的可控发电量。为了增加沼气和光伏电站向电网的总能源供应，介绍了一种沼气厂能源管理系统。描述并修改了系统参数，例如光伏电站的可变馈电或可控沼气厂CHP装置启动过程的功率斜坡，并适应了德国配电网中光伏电站和沼气厂的全球装机容量格。
