Methodology to Evaluate Distributed Control Strategies used in Distributed Energy Resource Applications

This paper provides a taxonomy and method to evaluate distributed control strategies used in distributed energy resource (DER) applications in power distribution grid. The paper explains the design process and provides performance metrics concerning implementation and further discusses different possibilities in distributed control for providing grid services. It focuses on identifying distributed control strategies proposed in recently published research and ongoing research activities, in terms of their control architectures, mathematical methods, and operational features. The deployment of existing control technologies and research results are also discussed by reviewing recent smart grid demonstration projects.
