Distributed Control of Loads to Provide Virtual Energy Storage for Renewable Integration

Prabir BarooahAssociate ProfessorUniversity of Florida, Mechanical and Aerospace Engineering

Energy storage is required to integrate large amounts of intermittent renewable energy sources, such as solar and wind, with the electric grid. Batteries for energy storage are still quite expensive. Another possibility is to exploit the inherent flexibility of power consumption in many electrical loads, such as air conditioning, to obtain "virtual energy storage". The power consumption of these loads is varied around a baseline so that they effectively behave like batteries that are charging and discharging. A critical requirement is to ensure that consumers' quality of service (QoS) is not adversely affected.

This talk describes recent work done at the University of Florida (UF) on the design, analysis, and experimental verification of control algorithms to obtain virtual energy storage from various types of loads. We argue that limiting the bandwidth of power variation (as opposed to the magnitude) is the key to ensuring QoS of consumers. This poses unique challenges in designing control algorithms, especially distributed control algorithms for a large number of loads.
