Enbala Power Networks unveiled a new version of its Symphony by Enbala platform today at DistribuTECH 2017 in San Diego, California.
“As a leader in demand flexibility, Enbala Power Networks is taking performance to the next level with a focus on scalability, accuracy and speed of response to grid services,” said Bud Vos, Enbala President and CEO. “Demand flexibility is certainly key to a distributed and sustainable energy future. However, we believe it’s time to look beyond the technology of yesterday towards solutions that can scale and operate to meet the demanding requirements of a distributed grid and a distributed energy future.”
The platform has been re-architected to take advantage of new technology advancements that better support a digitally connected, distributed energy-rich grid. The new features, which enabled Enbala to demonstrate live software optimization of 100,000 DER assets in real time to DistribuTECH attendees, include:
• Advanced machine learning through which the software can self-learn to continually improve its forecasting and the associated benefits. Machine learning is at the heart of many key components of the new Symphony software.
• Precise, continually updated asset modeling. The new platform leverages continuously streaming sub-metered sensor data to create digital twins of distributed energy assets that exist in the physical world. The software can precisely represent the real-time status and working conditions of millions of assets to fully optimize and improve the ROI of distributed energy resources and thereby defer capital expenditures.
• Time series forecast learning. The new technology uses a long short-term memory (LSTM) recurrent neural network (RNN) architecture to better predict behavior through new capabilities in understanding nuances of time series data and revealing difficult-to-detect patterns in events occurring over long periods of time.
• Agent-based control and optimization. Because the optimal mix of DER assets depends on the current state of these assets at any given moment in time, Symphony leverages a sophisticated agent-based bidding process that can assess millions of assets in sub-seconds.
“Symphony now has a new technology stack that wasn’t even a possibility just a year ago,” noted Mike Ratliff, Enbala Senior Product Executive. “We’ve been able to leverage a new IT reality to create a platform that enables utilities to control millions of assets and respond in seconds to the real-time energy balancing needs of the grid.” Ratliff pointed to several key benefits that the new platform brings to utilities, energy service providers and their customers.
• Improved accuracy - 99.9% accuracy in the precise set point control of each connected DER asset, 24x7, 365 days a year.
• Unlimited scalability – the ability to accommodate exponential growth of DERs on the grid. Symphony can easily manage one million assets with sub five-second response rates and can optimize one million assets every 100 milliseconds.
• Increased grid response speed, with the ability to respond to grid events every two seconds.
“Our goal in building the new platform was to optimize a million or more distributed energy assets connected to our network – always communicating and sending telemetry to the platform, pinpointing the optimal combination of DERs to respond to the constantly shifting needs of the grid 24 hours a day, 7 days a week, 365 days a year,” said Ratliff. “This is what we’ve done.”
