This is the final report on the Sacramento Municipal Utility District (SMUD) Smart Grid Demonstration Project. This project was part of the Electric Power Research Institute’s (EPRI’s) seven-year Smart Grid Demonstration Initiative. The project focused on integrating large-scale distributed energy resources (DER)—including demand response, storage, distributed generation, and distributed renewable generation—into a “virtual power plant” to advance widespread, efficient, and cost-effective deployment of utility and customer-side technologies in distribution and overall power system operations. A second focus for SMUD was to add technology and information systems to better enable SMUD to operate its distribution system resources more efficiently and cost effectively.
This report chronicles each of the SMUD Smart Grid projects from the planning and deployment phase to the analysis phase. Over the multi-year project, SMUD documented key pieces of information in the progress report to share with members of the demonstration project and with the power industry. The report will help stakeholders of the electric utility industry understand emerging technologies and the challenges associated with these technologies through field demonstrations. The overall goal of the project was to reveal the value of each project and the combined value of integrating multiple types of resources together at multiple levels within the grid.
This progress report describes each of the Smart Grid projects at SMUD. The report provides an overview, milestones, timeline, EM&V (evaluation, measurement, and verification) plan, hypotheses, results, and conclusions throughout the project, as well as the lessons learned in each project. The progress report was updated and published periodically throughout the demonstration initiative to inform other utilities of the activities occurring in each of the projects.
Application, Value, and Use
This report provides an overall project plan, as well as sub-project plans used by one utility to address the challenges associated with integrating DER and distribution system optimization; this plan supports one of EPRI’s goals—to use a diverse set of approaches and architectures to achieve integration of DER and distribution system optimization.
Over the duration of this seven-year project, associated research such as architecture design, lessons learned, cost/benefit analysis, and customer behavior was evaluated and described to members of the Smart Grid Demonstration Initiative—and, as appropriate, to the public—to help advance the industry in the deployment and benefits of the integration of distributed energy resources.
This report documents results from the individual projects within the demonstration and all previous versions of the associated progress reports, as they were available throughout the project. The initial project description served as a baseline. Results were tracked throughout the initiative and compared to the baseline. Operations experience, integration issues, and lessons learned revealed project and technological gaps that may warrant additional projects or demonstrations to be conducted to enhance the overall project.
The SMUD Smart Grid Demonstration project was a part of the larger EPRI seven-year collaborative initiative with multiple utility participants focused on the integration of distributed energy resources. EPRI provided the expertise for this industry collaboration effort, thus bringing significant value to the members while avoiding duplication of work and broadly sharing lessons learned with the industry.
