Short-term load forecasting of power system
Keeping in mind the end goal to guarantee the logical idea of optimization about power system, it is important to enhance the load gauging precision. Power system load estimating depends on exact information and study information, beginning from the history and current circumstance of power utilization, with a logical technique to anticipate the future improvement pattern of power load and change the law of science. Here and now load gauging is the premise of power system activity and examination, which is of extraordinary essentialness to the unit mix, financial dispatch, and wellbeing check.
To begin with, we utilize the information from 2012 to 2014 to set up the fractional slightest squares model to relapse investigation the connection between every day most extreme load, day by day least load, day by day normal load and each meteorological factor, and select the most astounding crest by watching the relapse coefficient histogram Day greatest temperature, day by day least temperature and day by day normal temperature as the meteorological components to enhance the precision of load estimating markers.
Furthermore, because of indeterminate atmosphere effect, we utilize the time arrangement model to anticipate the load information for 2015, individually, the 2009-2014 load information were dealt with, through the past six years of the information to conjecture the information for this time in 2015. The basis for the precision of the forecast is the normal of the standard deviations for the expected results and normal load for the past six years. At last, considering the atmosphere impact, we utilize the BP neural system model to foresee the information in 2015 and enhance the gauge comes about based on the time arrangement display.
