4. Enabling the 21st Century Grid with Enhanced Reliability and Security • Major Issues and Challenges • Future electric grid incorporating extensive distributed generation will require more complex system control and integration to ensure energy safety, security, and reliability including: • Real-time or near real-time assessment, control, and optimization of extensive distributed generation resources while maintaining power quantity and quality • Significantly improved control system cyber security • Improved intermediate and large-scale energy storage technologies to maintain renewable energy delivery reliability • Bidirectional power flow requires new advanced safety standards for distributed generation connection and operation in grid-tied and islanded modes • System control and hardware design and operational standards scalable for micro, intermediate, and utility-scale grid applications • Extensive testing and monitoring of control and operations approaches to verify cost and performance to reduce operational and safety risks to utilities and the public

8. Renewable and Distributed System Integration and Microgrids for DOE Objective To address current shortcomings of power reliability and security, Sandia is investigating advanced microgrid approaches to locate more secure and robust distributed energy generation and storage sources near loads as a way to better manage power generation and to improve overall power reliability and security. Microgrids are equally applicable to military, industrial, and utility distribution applications. Life-cycle Funding Summary ($K) Technical Scope Sandia’s microgrid research utilizes smart grid technologies to enable distributed energy generation and storage to be operated in both ‘grid-tied and ‘islanded’ modes. This enables energy demand/response management, increased use of distributed and renewable energy technologies, and improved cost-effectiveness, and reliability. The program leverages DoD, DOE, and industry funding to develop and evaluate smart grid technologies at DoD and other sites and testbeds. 8
