近年來隨著用電需求不斷增加與能源轉型政策加速推動，傳統集中式高碳排電廠發電比例逐年降低，分散式再生能源發電裝置占比快速提高，帶來更為即時與大量通訊與控制需求，以及龐大資料處理計算負擔。為解決傳統集中式電能管理系統無法即時、有效管理大量分散式電力設備之難題，區域微電網概念由此應運而生。透過將分散式控制架構引入電力系統，可藉由區域微電網電能管理系統控制區域內的分散式能源設備，以維持區域內即時電力供需平衡與確保區域內可進行孤島運行，區域微電網亦可作為子系統接受主電網的管理，微電網透過通訊技術和物聯網設備整合可以提高電力系統運作效能，但若缺乏適當安全管理，將使電力系統面臨網路攻擊威脅，進而對電力系統運作造成災難性影響，對於先進智慧電網與區域微電網，資安防護重要性不言可喻。
本論文提出一多重微電網與電力交易平台的區塊鏈資安防護架構，可應用於虛擬電廠與區域微電網，針對電力控制與電力交易資訊，進行全方位安全防護，可避免資料遭受洩漏、竄改、捏造等網路攻擊，同時具有高效能資料封包加密、解密與裝置身分驗證、授權管理能力，除可提高電力系統對網路攻擊的防護能力外，更可符合未來電能管理與電力交易需求。本論文所提出之資安防護架構於資料完整性、可用性、網路攻擊防護功能與現有文獻技術相比，更具全面性與效率。

In recent years, with the continuous increase in electricity demand and the accelerated promotion of energy transition policies, the proportion of traditional centralized high-carbon power plants has been decreasing annually. Meanwhile, the share of distributed renewable energy generation installations has been rapidly increasing, leading to more immediate and massive communication and control demands, as well as a substantial data processing burden.
To address the limitations of traditional centralized power management systems in effectively managing many distributed power devices, the concept of regional microgrids has emerged. By incorporating a distributed control architecture, these microgrids can manage distributed energy devices to maintain real-time power supply and demand balance and ensure islanding operation within the region. However, without proper security management, power systems are vulnerable to cyber-attacks that can severely disrupt operations.
This paper proposes a blockchain-based security framework for multiple microgrids and power trading platforms. This framework, applicable to virtual power plants and regional microgrids, provides comprehensive security protection for power control and trading information. It prevents data leakage, tampering, and fabrication by cyber-attacks, and offers high-performance data packet encryption, decryption, and device identity verification and authorization management capabilities.
