Summary

A novel safe deep reinforcement learning (DRL) framework has been developed to optimize building space heating, aiming to reduce energy consumption and enhance demand-side flexibility for power grids. The framework utilizes a deep deterministic policy gradient (DDPG) algorithm to learn optimal heating strategies, balancing occupant comfort, energy costs, and flexibility provision. To ensure operational safety and compliance with grid flexibility requests, a real-time adaptive safety filter is integrated. This filter guarantees full compliance with system operator demands and achieves significant energy and cost savings, up to 50% compared to rule-based controllers, while outperforming standalone DRL in efficiency metrics with minimal comfort violations.

Key takeaway

For building energy managers and smart grid operators evaluating advanced control systems, this DRL framework with its adaptive safety filter offers a robust solution. You can achieve up to 50% energy and cost savings while guaranteeing compliance with grid flexibility demands, making it a compelling alternative to traditional rule-based or standalone DRL controllers.
