With deeper research of wind key technologies, concern on operation of a micro-grid with wind power has been aroused greatly. Fully use of supply resources and demand resources of a micro-grid is determined by optimal planning of integrated resources. Considering that implementation of demand-side management is available to change the load profiles and decrease the variation extent of load during...
For a power grid integrated with wind farms, power output predication of wind turbines would influence the accessibility as well as its economy of dispatch schemes. We applied the GARCH algorithm into construct wind speed model, which has excellent characteristics to tracing the variation of the fluctuated time series. With power curve versus wind speed, wind power is easily gotten by putting the...
In recent years, with the rapid development of wind power, wind power plays an important role in the integrated grid. Uncertain output from wind generators might cause the dispatch of power system difficult. In this case, we applied a fuzzy variable to describe wind power. Then, we constructed a mathematical model for daily dispatch of a power system with wind power units. Following, we used uncertain...
Wind power forecasting is one of the key technical issues for a power system integrated with a large amount of wind farms. Based on analysis of the variation characteristics of wind speed, we applied econometrics theory into the modeling of wind speed, since GARCH has an excellent performance to tracing the variation of those fluctuating sequences. Using the wind power curve, the power output of a...
