The narrow definition of the digital power system (DPS) is proposed. The architecture, features and key contents of the DPS are presented, which include intelligent dispatching system, hybrid automatic control system and data sharing platform. The successful construction of the DPS can greatly improve the performances of power system operating and dispatching, which mainly reflect a fundamental increase of the ability of avoiding catastrophes resulting from blackouts of power supply, a significant improvement of economic efficiency of power system operation, and an improvement of decision efficiency of power system developing. The DPS describes a vision of the development of power system and the way to achieve this vision. At the same time, the paper also proposes the principles of the design and implementation of the DPS.digital power system, architecture, intelligent dispatching center, hybrid control, data sharing platform
The narrow definition of the digital power systemThe concept of the digital power system (DPS) was proposed in ref.[1], i.e. the DPS is a digital description and an optimization control system of a physical power system with its physical structure and characteristics, its technical and environmental performance, its economic management, its natural environment, the status of its employees, and its activities of research and development.The above definition of DPS can be considered as a general one, which mentions not only the digital energy production system (DEPS) that includes power generation, transmission, distribution, and consummation, but also the digital enterprise management system (DEMS) that includes power marketing, employees, financial management, etc. It also implies the technology supporting platform (TSP) for implementing DEPS and DEMS such as data sharing platform, information
