Abstract
The Smart Grid has emerged to address the shortcomings of one-way existing grid systems, and is the next generation power grid infrastructure that applies smart ICT (Information Communication Technology) to existing grid. The Smart Grid is expected to greatly improve the efficiency and reliability of future power systems with the demand for renewable energy resources. However, because major power facilities are interconnected through communication networks, Smart Grid’s cyber security is becoming an important issue. Cyber-attacks by malicious intruders can lead to serious incidents such as massive outages and the destruction of power network infrastructure, since the cyber-attacks can damage energy data, starting with personal information leakage from grid members. Therefore, as a solution to this issue we will suggest a secure smart energy management system based on the blockchain. The blockchain is a distributed data processing technology in which all users participating in the network distribute and store data. Applying blockchain technology to the Smart Grid will enable more secure management of energy data, and furthermore, it will contribute to the development of the future smart energy industry in the future.

As a result of the large-scale blackout in the world for many years and the damages caused by them, interests surrounding efficient management of energy resources to overcome the power shortage has increased
The Smart Grid, which is an infrastructure that minimizes various damages while maximizing energy efficiency based on problems such as power grid paralysis, unbalanced supply/demand of energy resources, environmental pollution, and use of renewable energy, becomes an issue
The Smart Grid is an infrastructure for automatic control, high power conversion, optimized energy demand management, and renewable energy management technology that uses smart ICT(Information Communication Technology) to power grid in order to solve the disadvantages of existing unidirectional grid system[1, 2]
Summary
As a result of the large-scale blackout in the world for many years and the damages caused by them, interests surrounding efficient management of energy resources to overcome the power shortage has increased. A system for efficient use and management of renewable energy such as wind and solar power generation is needed. The Smart Grid, which is an infrastructure that minimizes various damages while maximizing energy efficiency based on problems such as power grid paralysis, unbalanced supply/demand of energy resources, environmental pollution, and use of renewable energy, becomes an issue. The Smart Grid, which emerged for efficient and reliable energy management, is the generation power grid infrastructure, known as the intelligent grid. The Smart Grid has the advantage that it can work as an optimal energy management system to exchange information in real time by connecting the electricity production and distribution facilities and power consumers to the network. We propose a secure smart energy management solution using blockchain technology.
