Hitachi Review

Highlight

The power market reforms in Japan, which include wide-area operation, retail market deregulation, and the separation of generation and transmission, are expected to widen the scope of the networks that connect power systems in the future. Accompanying this is growing interest in security measures for power control systems together with recognition of the importance of these measures. Hitachi is drawing on its experience with power control systems built up over many years to investigate security measures that make the most of technologies for control and for information security by identifying what form power control security should take and analyzing security risks in terms of control, people (behaviors), and information. This article describes Hitachi’s approach to power control security and presents a case study of its work.
