Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional offline optimization methods are used to optimize power consumption factors separately, then device complexity is reduced, but productivity (real-time carbon footprint reduction capability) deteriorates
Solution Approach 1:
The system segments the complex optimization problem into multiple independent reinforcement learning agents, each responsible for a specific data center subsystem (cooling, workload scheduling, energy storage). This segmentation allows parallel real-time optimization of each subsystem while maintaining overall system coordination, resolving the contradiction between system complexity and real-time optimization capability.
Solution Approach 2:
A central coordinator acts as an intermediary that receives state information from all subsystem agents, integrates their individual optimization decisions, and ensures global carbon footprint reduction goals are met. This intermediary enables distributed real-time optimization without requiring a single complex centralized controller.
2Productivity
If multiple subsystems are optimized concurrently in real-time, then carbon footprint reduction effectiveness is improved, but device complexity increases
Solution Approach 1:
The system divides the concurrent optimization task into multiple specialized reinforcement learning agents, each handling a specific subsystem (HVAC cooling, IT workload scheduling, battery energy storage). This segmentation enables parallel real-time optimization across subsystems while keeping individual agent complexity manageable through domain-specific specialization.
Solution Approach 2:
The system merges the optimization capabilities of multiple subsystem agents through a collaborative framework where each agent contributes to the overall carbon footprint reduction goal. The agents share state information and coordinate decisions to achieve synergistic effects that greater than the sum of individual optimizations.
3Ease of operation
If static day-ahead optimization is used, then ease of operation is improved, but adaptability to changing weather and renewable energy availability deteriorates
Solution Approach 1:
The system transitions from static day-ahead optimization to dynamic real-time optimization using reinforcement learning agents that continuously adapt to changing conditions. The agents process real-time weather forecasts, renewable energy availability, and data center state information to dynamically adjust optimization decisions, enabling adaptability while maintaining operational simplicity through automated learning.
Solution Approach 2:
The reinforcement learning agents implement continuous feedback loops that monitor real-time system state, weather conditions, and renewable energy availability. This feedback enables the system to automatically adapt optimization strategies to changing conditions without manual intervention, resolving the contradiction between ease of operation and adaptability.
4Productivity
If comprehensive real-time optimization of all power consumption factors is implemented, then carbon footprint reduction is improved, but difficulty of detecting and measuring increases
Solution Approach 1:
The system segments the comprehensive optimization task into multiple focused reinforcement learning agents, each monitoring and optimizing specific power consumption factors (cooling power, IT equipment power, energy storage power). This segmentation simplifies measurement and control by breaking down the complex comprehensive monitoring task into manageable subsystem-specific measurements while achieving overall carbon footprint reduction.

AI summary
Systems and methods are provided for optimizing energy consumption, flexible load shifting, and battery operation decisions simultaneously in real-time through Reinforcement Learning (RL). Examples include obtaining states of a system comprising a plurality of subsystems and receiving, by RL agents, rewards from a digital twin of the system, the rewards comprising a plurality of rewards each associated with a subsystem. The example also include determining actions, by the RL agents, based on the states and each of the rewards. Each RL agent is associated with a subsystem and assigns a weight to a reward corresponding to the associated subsystem that is greater than weights assigned to rewards of the other subsystems. The system can then be controlled according to the actions to transition the system to updated states.
