Aggregating distributed energy resources for transmission system modelling
Abstract
The increasing deployment of renewable energy generation in distribution grids creates challenges for Voltage (V) control. One solution is to do Volt-VAr Control (VVC), that is, to use inverters reactive power (Q) capabilities to help stabilize V. This paper studies the relation between V and Q at the substation level when there are many inverters doing VVC along the distribution feeder. The goal is to find a simple model that accurately represents that relation and can thus be used in a transmission system model as a replacement for the true distribution feeder.
