The invention discloses a marketing, distribution and scheduling whole power grid modeling method of an integrated distribution power supply. The marketing, distribution and scheduling whole power grid modeling method of the integrated distribution power supply comprises the following steps: (1) establishing a high-voltage distribution network CIM (Common Information Model), 220kV / 110kV / 35kV station equipment and a 10kV line outgoing switch and load; (2) establishing a medium-voltage distribution network CIM and a 10kV / 20kV / 6kV feeder line; (3) establishing a low-voltage distribution network CIM (380 / 220V low-voltage user); (4) establishing a distribution power supply extended CIM; and (5) connecting the distribution power supply extended CIM into a power distribution automatic system. IEC (International Electrotechnical Commission) 61970 / 61968 and IEC61850 series standards are used as a basis, an object oriented technology analysis thought and a UML (Unified Modeling Language) are utilized to realize the integration modeling and application of distribution power containing the distribution power supply, and a foundation is laid for implementing an intelligent power distribution network application technology.
Description
technical field [0001] The invention belongs to the technical field of power distribution automation systems, and in particular relates to a modeling method for an integrated distributed power supply, distribution and deployment of the entire power grid. Background technique [0002] Distribution network is an important infrastructure for urbanization. With the acceleration of urbanization, the development of modern distribution network has ushered in a critical period where opportunities and challenges coexist. At the same time, under the encouragement of the national energy conservation and emission reduction policy, large-scale distributed power sources are connected to the distribution network one after another. The future distribution network not only has a large amount of information, but also has a complex structure, especially when the original one-way power supply network develops into The bidirectional power flow power supply network with distributed power generati...
