智能电网的概念已被引入作为传统电网的新愿景，以找出整合绿色和可再生能源技术的有效方法。互联网智能电网，也称为能源互联网，也正在成为一种创新的方法，以确保随时随地的能源。这些发展的最终目标是建立一个可持续发展的社会。然而，集成和协调大量不断增长的连接对于传统的集中式网格系统来说是一个具有挑战性的问题。因此，智能电网正在经历从集中式拓扑结构向分散式拓扑结构的转变。另一方面，区块链具有一些优秀的功能，使其成为智能电网范例的一个有前途的应用。在这篇文章中，我们的目的是提供一个全面的调查区块链在智能电网中的应用。因此，我们确定了可以通过区块链解决的智能电网场景的重大安全挑战。然后，我们提出了一些基于区块链的最新研究工作，这些研究工作在不同的文献中提出，以解决智能电网领域的安全问题。我们还总结了几个相关的实际项目，试验，和最近出现的产品。最后，我们讨论了将区块链应用于智能电网安全问题的基本研究挑战和未来方向。
The concept of smart grid has been introduced as a new vision of the conventional power grid to figure out an efficient way of integrating green and renewable energy technologies. In this way, Internet-connected smart grid, also called energy Internet, is also emerging as an innovative approach to ensure the energy from anywhere at any time. The ultimate goal of these developments is to build a sustainable society. However, integrating and coordinating a large number of growing connections can be a challenging issue for the traditional centralized grid system. Consequently, the smart grid is undergoing a transformation to the decentralized topology from its centralized form. On the other hand, blockchain has some excellent features which make it a promising application for the smart grid paradigm. In this article, we aim to provide a comprehensive survey on the application of blockchain in smart grid. As such, we identify the significant security challenges of smart grid scenarios that can be addressed by blockchain. Then, we present a number of blockchain-based recent research works presented in different literature addressing security issues in the area of smart grid. We also summarize several related practical projects, trials, and products that have emerged recently. Finally, we discuss essential research challenges and future directions of applying blockchain to smart grid security issues.
