Abstract: The support of information and communication technologies (ICT) for transnational interconnection of power dispatching and trading systems has important theoretical and practical significance for the construction of global energy interconnection. Based on the theory of cyber physical systems and SWOT analysis method, the related issues are studied and designed around the core architecture by using various existing technologies. The general architecture is proposed for the transnational interconnection of power dispatching and trading systems, including the conceptual model, technology framework, deployment architecture and functional interfaces. The key technologies are analyzed, such as the communication supports, interactive protocols, interchange of power grid models and related data, and application of information technologies. The assurance system is designed for security and reliablity. And an exemplary interconnection design is made for transnational interconnection of power dispatching and trading systems in Northeast Asia.

Key words: global energy interconnection, cyber physical systems (CPS), strengths weaknesses opportunities threats (SWOT), electricity market trading systems, dispatching and control system, information and communication technology (ICT)
