As renewable generation, especially wind and solar generation in the grid increase and become more distributed, grid energy management systems (EMS) are becoming increasingly important and complex. In this panel session, we will discuss the research opportunities and challenges related to EMS design and implementation with particular focus on the development of a unified framework for an EMS that can accommodate the additional capabilities that will be required in the 100% renewable energy future. Specifically, we aim to answer the following questions: What are needed to connect and manage all of these individual systems and components effectively? What software and hardware platforms should be used? Can a standard architecture be developed and used for the majority of applications? What needs to be designed differently for a power system with an increasing number of distributed resources?
