The global trend toward integration of distributed energy resources is opening doors to advanced, complex, and distributed marketplaces. Such advanced ecosystems, where utility-owned and non utility-owned assets can contribute toward grid operations, generally require distributed communication and grid architectures. We posit the potential of using Distributed Ledger Technologies (DLTs) in supporting such applications, although their full potential has not been fully used, for example in designing long-term scalable solutions in operational technology applications. This is partly due to the lack of standardization across and between different DLTs, as well as other supporting building blocks (e.g., communication protocols). This paper attempts to address this gap by proposing a DLT cybersecurity stack specifically designed for researchers, DLT technology developers, and end users (such as utilities). The DLT cybersecurity stack has been notionally mapped to related cybersecurity components, namely the Open Systems Interconnection (OSI) model, the Transmission Control Protocol/Internet Protocol (TCP/IP) suite, and existing Smart Grid architecture frameworks. In addition, the paper discusses several cybersecurity implications, and demonstrates the potential uses of the DLT cybersecurity stack through multiple power and energy use cases. It is important to note that the stack can be also applied to the DLT use cases that are outside the power and energy domain. This work was performed by the Cybersecurity Task Force under the IEEE P2418.5 Blockchain for Energy Standard working group that part of the IEEE Power and Energy Society’s Smart Buildings, Loads, and Customer Systems (SBLC) technical committee.

分布式能源整合的全球趋势为先进、复杂和分布式市场打开了大门。这种先进的生态系统，公用事业拥有和非公用事业拥有的资产可以为电网运营做出贡献，通常需要分布式通信和电网架构。我们假设使用分布式账本技术 (DLT) 来支持此类应用程序的潜力，尽管它们的全部潜力尚未得到充分利用，例如在运营技术应用程序中设计长期可扩展的解决方案。这部分是由于不同 DLT 之间和之间缺乏标准化，以及其他支持构建块（例如，通信协议）。本文试图通过提出专门为研究人员、DLT 技术开发人员和最终用户（例如公用事业）设计的 DLT 网络安全堆栈来解决这一差距。DLT 网络安全堆栈在概念上已映射到相关的网络安全组件，即开放系统互连 (OSI) 模型、传输控制协议/互联网协议 (TCP/IP) 套件和现有的智能电网架构框架。此外，本文讨论了几个网络安全影响，并通过多个电力和能源用例展示了 DLT 网络安全堆栈的潜在用途。值得注意的是，堆栈也可以应用于功率和能源领域之外的 DLT 用例。这项工作由 IEEE P2418 下的网络安全工作组执行。
