The objective of this project was described as to "conduct a pilot scale “proof-of-concept” test in San Diego, CA of how information-based technologies and DER may increase utility asset utilization and reliability" . Goals of this project include :
- Achieve > 15% reduction in feeder peak load through the integration of multiple, integrated DER–distributed generation (DG), advanced energy storage, and price driven load management
- Demonstrate capability of Volt-Amperes-Reactive (VAR) management- coordinating the DER with existing VAR management/compensation tools.
- Demonstrate ‘self-healing’ networks through the integration of Feeder Automation System Technologies (FAST) into microgrid operations
- Demonstrate the integration of Advanced Metering Infrastructure (AMI) and Outage Management System/Distribution Management System (OMS/DMS) into microgrid operations
- Demonstrate the capability to use automated distribution control to intentionally island customers in response to system problems
This SDG&E microgrid project was designed to integrate a U.S. Department of Energy (DOE) component, which was to focus on utility-side applications, and a California Energy Commission (CEC) portion, focusing on customer-side applications . DOE contributed $7.2M towards (CEC contributed $2.8M towards) the total project cost over 3 years. For the DOE portion, the project primarily involved integration of 5 technologies: distributed energy resources (DER) and VAr, feeder automation system technologies (FAST), advanced energy storage (AES), OMS/DMS system, and price driven load management (PDLM). For the CEC portion, the project initially involved integration of the following customer based technologies: remote controlled demand response devices (e.g. thermostats), solar panels, battery storage, plug-in hybrid electric vehicles (PHEV’s), and grid-friendly appliances. The project team also performed a cost/benefit analysis for full-scale deployment.
