Abstract

The invention discloses a source network load coordinated operation simulation system which is characterized by comprising a data input module, an operating calculation module and a result output module, wherein the data input module is used for inputting relevant data simulated by the system; the operating calculation module is used for performing operating simulation and calculation in the 'source-network-load' coordinated operation process; and the result output module is used for outputting data and information calculated and analyzed by the operating calculation module. According to the source network load coordinated operation simulation system provided by the invention, various factors influencing the wind speed and contribution of a wind power plant are considered, so that wind power plant simulation is scientific, the contribution of the wind power plant and the 'source-network-load' is subjected to coordinated operation simulation; and therefore, the operating simulation result is accurate, and the power grid can achieve the effects of improving large-scale wind power access ability, reducing the new energy consumption cost of the system and improving the utilization rateof renewable energy sources, and the system has great practical significance for formulating an electric power development plan in a receiving-end region and realizing the wind-power optimized layout.

Description

technical field [0001] The invention relates to the technical field of electric power systems, in particular to a source-grid-load coordinated operation simulation system. Background technique [0002] At present, my country's wind power is developing vigorously, especially in the receiving area, the large-scale wind power connection has brought new challenges to the power system and is gestating major changes. On the one hand, the development of wind power will make the power system more low-carbon, economical, and efficient; Substantial changes in the tide increase the operational risk of the system. [0003] In view of the random fluctuation of wind power output and the complex operation of the power system after large-scale wind power is connected to the grid, Du Hongwei, Lu Wen and others proposed "Research and Application of Urban Distribution Network Power Source Network-Load Interactive Optimal Dispatch Technology" in 2016. The program mainly focuses on On the powe...
