Construction of energy internet technology architecture based on general system structure theory

Abstract

Based on electrical power systems, leveraging renewable energy generation technology, and information technology, the energy internet fuses power grids, gas networks, heat/cold supply networks, electric transportation networks, etc. into an interconnected energy sharing network. The energy internet is an important technology for promoting renewable energy integration and improving energy efficiency. However, due to the complexity of multiple energy networks and the significant differences between them, the planning, operation, and control of energy internet presents several technical difficulties. Mainstream research only divides the complex system of energy internet into three systems: energy grid system, value creation system, and information support system. Under each system, how the State Grid Corporation of China develops related technologies has not been detailed, and the technical system framework composed of internal logical connection of each technical point is not yet mature. Based on general system structure theory, the technical system framework for the provincial power grid corporations to construct regional energy internet is constructed, and it proposes a technical route for the development of provincial energy internet based on local conditions in this paper. It can guide different affiliated companies in the field of energy internet technology that should be focused on research, and support the development of related technologies.
