The Enabling Extreme Real-Time Grid Integration of Solar Energy (ENERGISE) funding program develops distribution planning and operation solutions to enable dynamic, automated, and cost-effective management of distributed and variable generation sources, like solar, onto the grid. These software and hardware solutions are highly scalable, data-driven, and capable of real-time system operation and planning. Solutions developed under ENERGISE enable grid operators to gather up-to-the-minute measurement and forecast data from distributed energy sources and optimize system performance using sensor, communications, and data analytics technologies.
The project selections were announced on January 31, 2017. Read the progress alert.
ENERGISE solutions focus on improving four distinct layers within a distribution system:
- Device and Local Control Layer – Projects will develop and integrate low-cost, plug-and-play smart sensor and local control devices for day-to-day distribution system operation that integrate multiple functionalities into a single device in order to reduce system cost and integration complexity.
- Telecommunications and Data Layer – Projects will develop efficient and cost effective methods to collect, transport, process, and store the measurement data necessary for real-time system operation and planning analysis, which will result in fully automated operations with an integrated data view of the entire system and without operator intervention.
- Traditional System Layer – Projects will create interfaces that link the existing planning and operation tools with real-time measurement data and control from the Telecom & Data Layer, and with the advanced power system analysis from the Enhanced System Layer. Measurement data and control functions from PV inverters and energy storage will be fully integrated into grid planning and operation.
- Enhanced System Layer – Projects will develop advanced methods to model, simulate, and predict distribution power system behaviors using large data sets in order to manage high penetration solar generation. These methods include real-time distribution power flow, optimal distribution power flow, distribution system state estimation, stochastic analysis, predictive analysis, and machine learning techniques.
Distributed variable generation sources like solar energy are a key driver for the transformation of the electric power grid from today’s centralized, static, and rigid system towards a more distributed, dynamic, and flexible system. ENERGISE focuses on improving distribution system planning and operations by developing distribution system planning and grid operation solutions compatible with existing grid infrastructure to enable the addition of solar at 50% of the peak distribution load by 2020. Looking further into the future, ENERGISE is also developing transformative and highly scalable technologies compatible with advanced grid infrastructure to enable solar at 100% of the peak distribution load by 2030.
