California Rule 21 requires identification of customer-side Distributed Energy Resources (DER) controls, communication technologies, and standards. Besides reducing customer's need to grid power, the customer-side DER plays a key role for Demand Response (DR) options. The customer-side DER technology can be leveraged to enable optimized cost, energy, and carbon choices. This project studies cost-effective communication technologies for DER integration and interoperability using tools and open standards, as well as optimization models for resource planning based on day-ahead price notifications.
In this project, we identify architectures and customer engagement strategies in dynamic pricing DR transactions to generate a feedback of load flexibility profiles, status, and schedules. In particular, we focus on day-ahead Real-Time Pricing (RTP) and day-ahead Peak Day Pricing (PDP), and use the Open Automated Demand Response (OpenADR) information exchange standard for the communication between the customer and the DR-service-provider, and use the Distributed Energy Resources Customer Adoption Model (DER-CAM) for the customer-side DER planning.
Furnishing customers with an optimized DER planning tool, such as DER-CAM, and closing the loop between the utility and customers’ DER planning tools benefits both the utilities and the customers. On one hand, customers gain from cost savings achieved through optimized DER planning in response to day-ahead dynamic pricing. On the other hand, inclusion of such tools in the utility/customer loop benefits the utility by increasing predictability in the day-ahead load profile. The application of this closed loop model is not limited to day-ahead planning and the same model can also be used in shorter time-frames.
