  Power systems are growing rapidly, due to the ever-increasing demand for
electrical power. These systems require novel methodologies and modern tools
and technologies, to better perform, particularly for communication among
different parts. Therefore, power systems are facing new challenges such as
energy trading and marketing and cyber threats. Using blockchain in power
systems, as a solution, is one of the newest methods. Most studies aim to
investigate innovative approach-es of blockchain application in power systems.
Even though, many articles published to support the research activities, there
has not been any bibliometric analysis which specifies the research trends.
This paper aims to present a bibliographic analysis of the blockchain
application in power systems related literature, in the Web of Science (WoS)
database between January 2009 and July 2019. This paper discusses the research
activities and performed a detailed analysis by looking at the number of
articles published, citations, institutions, research areas, and authors. From
the analysis, it was concluded that there are several significant impacts of
research activities in China and the USA, in comparison to other countries.
