Flexergy: Bridging Machine Learning and Controls for Volatile Energy Markets


Abstract: In December 2014, the average price of wholesale electricity in the PJM market surged from $32/MWh to $2680/MWh - an 83x increase in 5mins. Demand response (DR) is becoming increasingly important as the volatility on the grid continues to increase. Current DR approaches are predominantly manual and rule-based or involve deriving first principles based models which are extremely cost and time prohibitive to build. We consider the problem of data-driven end-user DR for large buildings which involves predicting the demand response baseline, evaluating fixed rule based DR strategies and synthesizing DR control actions. Our machine learning algorithms capture building models with 96-98% accuracy in minutes. By bridging machine learning with controls, we perform closed-loop control for DR strategy synthesis across commercial buildings in a scalable manner. Our data-driven control synthesis algorithm outperforms rule-based DR for large DoE commercial reference buildings and leads to consistent +30% electricity cost savings across the year. Our methods have been integrated into commercial SCADA systems and acts as a recommender system for the building’s facilities manager and provides interpretable control actions to meet the desired load curtailment while maintaining operations and maximizing the economic reward. An Interactive Energy Analytics engine allows the user to ask buildings questions on their predicted operations and makes Demand Response easy with procedurally generated energy dashboards for open-ended questions.

Bio: Rahul Mangharam is the CEO of Flexergy focused on cost-efficient energy controls and analytics for volatile energy markets. He is also an Associate Professor in the Dept. of Electrical & Systems Engineering and Dept. of Computer & Information Science at the University of Pennsylvania.
