Abstract
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 smart grid paradigm. In this paper, we have an aim to
provide a comprehensive survey on 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 literatures
addressing security issues in the area of smart grid. We also summarize several
related practical projects, trials, and products that have been emerged
recently. Finally, we discuss essential research challenges and future
directions of applying blockchain to smart grid security issues.
