Intelligent distributed type wind power generation system capable of adjusting voltage and power

Abstract

Disclosed is an intelligent distributed type wind power generation system capable of adjusting voltage and power. According to the power generation grid, the power generation power changes of wind power equipment can be predicted; the grid-connected point voltage information of the large power grid can be tracked; the dispatching instruction of the large power grid can be obtained in real time; the battery capacity of a storage battery module can be detected in real time; the discharging section of an energy storage system can be set; the energy of the energy storage system can be optimized and managed based on an SOC hierarchical control policy; the redundant active power of the wind power generation equipment can be absorbed in time, or the deficient active power of the wind power equipment can be supplemented; the influence on the power grid from the wind power generation system can be reduced; it is ensured that the power generation system can participate in the voltage regulation of the large power grid in grid connection according to the requirement of the large power grid; and the voltage stability in the grid connection operation can be ensured.

Description

Technical field [0001] The invention relates to an intelligent distributed wind power generation system with adjustable voltage and power. Background technique [0002] The energy and environmental crisis has become an important issue affecting the sustainable development of human beings, and the utilization of clean and renewable energy is the fundamental way to solve this problem. With the maturity of wind power generation, photovoltaic power generation, wave power generation and other renewable energy power generation technologies, more and more renewable energy power generation systems are connected to the power grid in a distributed manner to meet people's daily production and living electricity needs. [0003] The power generation system based on wind power and photovoltaic power generation, as a supplement to the ultra-high voltage, long-distance, and large grid power supply mode, represents a new development direction of the power system. There are currently two pow...

AI Technical Summary

Problems solved by technology

From the above analysis, it can be seen that in the existing wind power generation grid-connected configuration system, the utilization of wind energy can only take a small section in the middle. The waste, more importantly, wind turbines are frequently cut in and out of the power grid, which has a great impact on the power grid

This wind power grid-connected mode cannot realize continuous power transmission to the grid, and can only transmit power to the grid in a certain wind range
