Aggregating distributed energy resources for transmission system modelling

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.

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.
