浅议微电网极端条件下的电压变化

摘要

配电网中不同类型分布式能源( DER)的并入对用户和配电网服务提供商的电压有显著的影响，这种影响取决于电压的变化和并入配电网的DER的容量。分析微电网极端条件下的情况，以便估计能接到微电网的DER的最大容量和电压变化量而不会负面影响用户。估计电压变化与能接入配电网的DER的数量之间的关系，理论上推导出微电网极端条件下的小型和大型配电系统的电压变化公式。%Distributed energy of different types of distribution network ( DER) is incorporated into all have significantly influence the voltage to the user and the distribution network service provider, capacity of this kind of influence the change of voltage de-pendent and incorporated into the distribution network DER. Micro grid under extreme conditions, in order to estimate the maxi-mum capacity and voltage variation can be connected to the micro grid DER without negative impact on users. To estimate the re-lationship between the number of voltage changes and can access to distribution network DER, voltage variation formula is theoret-ically derived micro grid under extreme conditions of small and large distribution system.
