The Modeling And Simulation Of Wind Storage Integration System

With the continuous decrease of fossil fuels as well as the cause of air pollution index has soared, greatly influenced People’s daily life.At the same time in order to avoid energy using is at the expense of the natural environment, national energy strategy is from the traditional fossil energy towards zero pollution new energy change.Wind power is cracking the air pollution index surged because of its clean and renewable.It is the best choise for energy shortage problem of the human facing.Due to the restriction of unstable factors such as wind power output volatility combined with traditional generators, such as water and electricity, thermal power cannot jump-start makes wind power can’t mass grid.Energy storage system because of its flexible electrical stimulation conversion characteristic of fast response to the increases and the gaps of the new energy power generation system become the best choice for wind power and other intermittent renewable energy grid.In order to make to make full use of energy storage in new energy power generation system, the wind storage integration system research has become the hot spot.This article from the following aspects to study for intermittent new energy sources such as wind power can’t friendly to power grid.First analyzes the basic principle of doubly-fed wind power generation system structure, the basic principle of coordinate transformation,based on the coordinate transformation to build the simulation model of the motor;Analyzed the basic structure of the lead-acid battery and mathematical model of charging and discharging,based on doubly-fed wind turbine machine side, grid side of the control strategy,propose theoverall control of the wind storage integration system considering wind turbines make electricity, the load required power and battery energy storage system.Secondly set up web side converter again,build the open circuit fault simulation model to analyze all kinds of open circuit condition operation.Finally,simulation analysis of the doubly-fed wind power system, lead-acid battery charge and discharge and the wind storage integration system.Contrast the lead-acid storage constitute the wind storage integration system reduces the effect of wind power fluctuations under the control strategy.In order to verify the correctness of the wind power system model and energy storage for Unstable new energy sources such as wind power grid volatility calm effect.Set up doubly-fed fan, lead-acid storage system wind energy storage system integration system of use the energy storage system to improve the quality of wind power simulation model,the simulation verify the validity of the model.
