Solution Overview

Problem

Current methods for managing energy storages in cellular networks do not effectively consider network load, RBS locations, or load-dependent energy consumption, leading to inefficiencies in energy utilization and increased carbon footprint and operational costs.

Innovation Solution

A computer-implemented method using reinforcement learning to manage energy storages across multiple sites in a network, where a simulated environment is created based on power consumption data, and a reinforcement learning system is trained to optimize energy storage actions such as charging and discharging, considering constraints and aiming to maximize reward based on energy cost and carbon footprint reduction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If traditional energy management methods are used in cellular networks, then network operations can be maintained, but energy utilization efficiency is low and carbon footprint increases

Engineering Contradiction:
Improveenergy utilization efficiencyVSAvoidcarbon footprint
Core Design Contradiction:
Loss of energyVSObject-generated harmful factors

Solution Approach 1:

The patent implements dynamic energy management by training reinforcement learning agents that continuously adapt charging and discharging decisions based on real-time network load conditions, traffic patterns, and energy storage states. This dynamic approach replaces static traditional methods, optimizing energy utilization efficiency while reducing carbon footprint through load-dependent energy consumption management.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system employs feedback mechanisms where reinforcement learning agents receive continuous monitoring data on network load, energy storage levels, and power consumption, then adjust their charging and discharging actions accordingly. This closed-loop feedback enables the system to learn from past decisions and improve energy management performance, directly addressing the contradiction between energy efficiency and carbon emissions.

Inventive Principle:
Principle #23Feedback

2Reliability

If energy storages are managed independently at each site, then local power supply stability is maintained, but overall network energy utilization efficiency is reduced

Engineering Contradiction:
Improvelocal power supply stabilityVSAvoidnetwork energy utilization efficiency
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent merges independent site-level energy management into a coordinated network-wide system by deploying reinforcement learning agents that consider inter-site energy transfer opportunities. The system combines local reliability requirements with network-wide optimization, allowing energy storages at different sites to be charged or discharged based on overall network conditions rather than isolated local conditions, thereby improving both reliability and energy utilization efficiency.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The reinforcement learning framework provides a universal energy management approach that can be applied across multiple sites with different local conditions. The same RL agent architecture adapts to various site configurations, load patterns, and energy storage capacities, enabling coordinated management that maintains local reliability while optimizing network-wide energy utilization through multi-functional decision-making.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Measurement precision

If reinforcement learning is trained on historical power consumption data, then accurate predictions can be achieved, but training time and computational resources increase

Engineering Contradiction:
Improveprediction accuracyVSAvoidtraining time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies partial action by training reinforcement learning agents on selectively relevant historical power consumption data rather than complete datasets. The system identifies and prioritizes key features and time periods that most influence energy management decisions, achieving sufficient prediction accuracy for practical deployment while reducing training time and computational resource requirements through focused data selection.

Inventive Principle:
Principle #16Partial or excessive action
