Literature Survey - Essay Example The authors found that temperature was the main driver in load forecasting. Increase in temperature was also found to affect the transmission of electric power negatively, by restricting the load carrying capacity of the transmission and distribution lines. They also found that in the United Kingdom the relationship between demand and temperature was inversely proportionate, due to the lower temperatures experienced in the United Kingdom. In summer though the general average demand was found to fall due to the lack of heating requirements, when temperatures exceeded twenty degrees Celsius demand increased, because of enhanced air-conditioning and cooling loads (Hor, Watson & Majitha, 2005) Among the several weather factors, temperature is the most influential weather factor that impinges on consumption of electricity. Rise in temperature in winter reduces consumption of electricity, because of lower demand for heating. High temperatures however, increase demand on electricity for air-conditioning and refrigeration requirements. The speed of prevailing winds may have some impact on air-conditioning and cooling from fans. There general effect of cooling from higher wind speed. Rainfall, relative humidity and are sunshine are three more factors that affects the demand of electricity. Wet conditions are increased during rainfall and enhanced relative humidity, increasing demands for heating in winter. In addition the cloud cover during rainy periods diminishes the heating effect of sunshine. The demand during extremes of heat and cold is non-linear with regard to temperature, but the model shows better forecasting of demand by the addition of these factors for the summer months (Hor, Watson & Majitha, 2005). Moving closer to the study area of the impact of weather on electricity consumption in Sacramento, California, Franco and Sanstad, 2005, studied the possible enhanced stress on the
