Problems solved by technology
Each power system manufacturer has its own grid modeling methods, but due to differences in developers or system versions, there are great differences in the structure of the created models, graphics or databases, forming a certain degree of "information islands", resulting in It becomes very difficult to share information and achieve some degree of interoperability between different systems

Embodiment
[0072] In the embodiment of the present invention, two new energy stations are connected to the main network. The main network includes: a 500kV substation and a 220kV substation, which are respectively D and E, and E is a collection station for new energy to go online. Two new energy wind farms B and F;
[0073] The main network CIM model is as follows:
[0074]
[0075]
[0076]
[0077]
[0078] The CIM model of new energy station B is as follows:
[0079]
[0080]
[0081]
[0082] The CIM model of the new energy F station is as follows:
[0083]
[0084]
[0085] Perform the following steps:
[0086] 1) Preset the control period of the automatic voltage control system AVC to 5 minutes;

The invention provides a CIM-based new energy model splicing method for AVC control, and belongs to the technical field of automatic voltage control of a power system. The method comprises the following steps of firstly collecting a complete provincial power grid CIM model file and CIM model files of various new energy stations in each control cycle; splicing CIM models of the new energy stations into a provincial power grid CIM model through an artificially specified line, a main transformer and corresponding parameters to form a new complete power grid model comprising the new energy stations; and finally achieving control of an automatic voltage control system on the new energy stations. According to the method provided by the invention, full-automatic model splicing can be achieved; the requirements of the AVC control are met; and the problem of voltage control of a new energy power plant is solved.
Description
technical field [0001] The invention belongs to the technical field of automatic voltage control of power systems, and in particular relates to a CIM-based new energy model splicing method used in AVC control. Background technique [0002] Automatic voltage control (hereinafter referred to as AVC, Automatic Voltage Control) system is an important means to achieve grid security (increase voltage stability margin), economy (reduce network loss), and high-quality (increase voltage qualification rate) operation. The AVC system architecture is based on the grid energy management system (EMS), which can use the real-time operation data of the grid to scientifically make the best reactive power and voltage adjustment scheme from the perspective of overall grid optimization, and automatically send it to power plants, substations, and lower-level grid dispatchers Institutional execution. The AVC system takes voltage safety and high quality as constraints, and aims at system operatio...
