Planning operation system of power system

Abstract

The invention belongs to the technical field of the power, and discloses a planning operation system of a power system. Data management in the full-life cycle at the planning stage and the operation stage can be realized through a power element modelling module, a parameter management module and a power system form management module; and meanwhile, the lowest total power grid operation cost in theplanning cycle is used as the target function through an optimum planning module; a power grid planning model containing an energy storage system is constructed according to the parameter informationso as to obtain an optimal solution of the planning model. The corresponding power grid operation planning scheme is obtained according to the optimal solution; by adopting the scheme disclosed by the embodiment of the invention, the planning scheme with the lowest total power grid operation cost containing the energy storage system can be obtained, and the actual operation effect of the planningscheme is improved.

Description

technical field [0001] The invention belongs to the field of electric power technology, and in particular relates to a planning operation system of an electric power system. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] The main structure of the power system includes power sources (hydropower plants, thermal power plants, nuclear power plants and other power plants), substations (step-up substations, load center substations, etc.), power transmission, distribution lines and load centers. The power points are also connected to each other to realize the exchange and adjustment of electric energy between different regions, thereby improving the security and economy of power supply. The network formed by transmission lines and substations is usually called a power network. The information and control system of the power system consists of various testing equipment, communication equipment, safety pro...

AI Technical Summary

Problems solved by technology

[0007] In the existing power system planning, there are often problems such as inconsistency in grid data statistics sources, incomplete data information, etc., resulting in in-depth analysis and research work, and low level and efficiency of planning research; at the same time, the actual operation effect of the existing planning scheme is not ideal

[0008] The sliding mode controller coefficient design method in the existing inverter only provides a selection principle, which cannot give a more accurate sliding mode coefficient
