  Smart grid is the modern two way mechanism combining the power grid, control
center, smart metering facility, energy routing and customer demand response
services. The system being complicated, security vulnerabilities are paramount
for the sound operation and process continuation. Since smart grid connects
with the end user to the energy providers, these two parties can interact with
each other within the whole energy management work flow. In this regard, game
theory provides effective insights in the analysis of security measures for
smart grid. The mentioned parties will be the players in the game model to
provide a solution for the various threats to the grid aspects. In this work, a
brief review has presented with the existing approaches to the threat models
for divergent sectors of the smart grid. The solution approaches to these
threats are based on the game theoretical approaches that connect the attackers
and defenders in the scenarios.
