可再生能源的整合对于所有电压等级的网络都是一个挑战。可再生能源的馈入对资产负载和无功功率管理具有影响，以将节点电压保持在允许的电压区间内。通常，叠加网络提供所需的无功功率。然而，通过已安装的可再生能源在当地提供也是可能的。此外，它们对叠加网络的无功功率的贡献也是可以想象的。分析了风电场和光伏发电场注入无功功率后，配电网向上级电网提供无功功率的理论潜力。考虑了电压带违规和资产负载等技术限制。分析是基于德国配电网的三个常见的电压水平的代表性网络数据。
The integration of renewable energy sources is a challenge for networks of all voltage levels. The feed-in of renewable energy sources has an impact on asset loadings and reactive power management to keep the nodal voltages within in the allowed voltage interval. Usually, the overlayed network provides the required reactive power. However, the local provision by the installed renewable energy sources is possible, too. Additionally, their contribution of reactive power to the overlayed network is also conceivable. This paper analyses the theoretical potential of distribution networks to provide reactive power to the superior network with reactive power injection of wind and photovoltaic power plants. Technical restrictions like voltage band violations and asset loadings are considered. The analysis is based on representative network data of the three usual voltage levels of German distribution networks.
