Abstract

The invention relates to the technical field of electric power systems, and is a method and system for coordinated control of reactive power voltage of energy storage and new energy power stations, which simplifies the structure of the power grid in the receiving end area, forms reactive voltage control partitions, and implements control strategies in each time period implementation, and then determine the reactive power optimization model under the normal operation mode, the energy storage and SVG coordinated voltage control scheme, pass the fault operation mode for inspection, if it fails, Jianli reactive power optimization model under the fault operation mode, and if it passes, determine the energy storage The power station and SVG coordinate the voltage control scheme, and repeat the analysis of the optimal control strategy of the energy storage power station and SVG reactive power voltage in the control area of ​​each time period during the dispatching period. It can effectively stabilize the fluctuation of new energy output and the voltage fluctuation problem caused by output fluctuation, which is conducive to reducing the network loss of the control zone and ensuring the power grid control effect of the central node; it is not only conducive to the overall reactive power optimization of the power grid, but also conducive to Improve the voltage control capability of the weak zone of the receiving end power grid.

Description

A method and system for coordinated control of reactive power and voltage of energy storage and new energy power stations technical field The present invention relates to the technical field of electric power system, be specifically related to a kind of coordination of energy storage and reactive power voltage of new energy power station Control method and system. Background technique The proportion of new energy in the power grid is increasing, and the rational arrangement of its operation mode must fully consider its own impact on the output of new energy. The disturbance tolerance of power fluctuations can ensure the safe operation of the power grid and the reliable consumption of new energy. Many new energy stations At the end of the power grid, the power grid construction is relatively weak. For the AC and DC receiving end power grids, it is more vulnerable to the peak-to-valley difference of new energy output and the high power consumption. The impact of rate ...
