Abstract

Aggregation of electric resources is a fundamental function for the operation of power grids at different time scales. In the context of a recently proposed framework for the real-time control of microgrids with explicit power setpoints, we define and formally specify an aggregation method that explicitly accounts for delays and message asynchronism. The method allows to abstract the details of resources using high-level concepts that are device- and grid-independent. We demonstrate the application of the method to a CIGRÉ benchmark with heterogeneous and low-inertia resources.
