Summer daily peak load forecasting considering accumulation effect and abrupt change of temperature

For the distinctive power load and resource characteristics in an area, the relationship is analyzed between regional peak load and typical meteorological factors in summer. The forecasting model for daily peak load in summer is established, considering not only the general meteorological factors such as season, temperature, humidity, precipitation and the continuous sunny days, but also the persistent drought, the average temperature difference, the atmospheric conditions, human comfort and other factors. Particularly, due to the prolonged heat or abrupt change, the forecasting model is revised using the accumulation effect with high temperature and substitute average value for the abrupt change temperature. The calculated results show that the revised forecasting model is more accurate and feasible.
