In recent years, there has been a rapid increase in the connection of Distributed Energy Resources (DER) to the electric distribution grid. As the distribution grid is modernized to overcome challenges and enable expanded deployment of DER, consumers are becoming motivated to manage their electricity consumption and reduce their environmental impact while regulatory bodies are working to enable DER, eliminate old restrictions, and encourage new development and incentives. DER costs are dropping and communication technologies are making DER more attractive for residential, commercial, industrial, and utility use.
Challenges remain with connecting DER devices. These include the capacity of distribution networks to handle additional generation, the impact of two-way power flow, over-voltage and frequency variation, and system planning.
A key component of DER integration is the need for well-defined communication architectures and modern protocol standards. Stakeholders have an increased need to communicate electronically. This opens up the need for advanced control algorithms that enable DER to participate as part of a number of solutions to maximize the investment in DER and the support infrastructure needed.
This paper looks at the advantages and requirements of a communications structure, and ways to abstract the complexity of DER types. This can simplify the development of DER services and business applications to maximize the utilization of DER investments, and create a vision of how to move forward with DER integration communication systems.
