摘要

本研究介绍了Q-GRID SMART，这是一个分散的、支持区块链的住宅能源管理平台，集成了基于物联网的监控、预测分析和交互式用户仪表板。在卡塔尔多哈的4196个家庭进行了为期一个月的试点，机器学习模型（GRU, Bi-LSTM）预测了能源消耗、成本和二氧化碳排放，RMSE = 160.9 kWh, MAE = 120.3 kWh。部署后的调查（n = 312）表明，净推荐值为+42,87%的人表示能源意识得到了改善。该平台平均每个家庭每月减少16.8%的电力和145.4公斤的二氧化碳排放。我们进一步分析了区块链延迟和确认时间如何影响实时控制和用户体验，并提出了通过边缘控制循环、批处理和第2层解决方案（状态通道、卷取）进行缓解的建议。这些结果表明Q-GRID SMART为公用事业和家庭提供可扩展、安全和以用户为中心的能源管理解决方案的潜力。

Q-GRID SMART: A blockchain-enabled smart home energy management and analytics system

This study presents Q-GRID SMART, a decentralized, blockchain-enabled residential energy management platform integrating IoT-based monitoring, predictive analytics, and an interactive user dashboard. In a one-month pilot across 4,196 households in Doha, Qatar, machine learning models (GRU, Bi-LSTM) forecasted energy consumption, cost, and CO₂ emissions with RMSE = 160.9 kWh and MAE = 120.3 kWh. Post-deployment surveys (n = 312) indicated a Net Promoter Score of +42 and 87% reported improved energy awareness. The platform achieved an average 16.8% electricity reduction and 145.4 kg CO₂ savings per household per month. We further analyze how blockchain latency and confirmation times affect real-time control and user experience, proposing mitigation via edge control loops, batching, and Layer-2 solutions (state channels, rollups). These results demonstrate Q-GRID SMART's potential to deliver scalable, secure, and user-centric energy management solutions for utilities and households.
