District energy requirement prediction

Analysing the data of heating and steam users in the Tianjin Airport Economic Development District, finds that energy consumption per square meter area is notably different among consumers. Suggests that heat consumption be determined by the users’ character and that heat meters should be installed for charging. Predicts that the total cooling load is 229.75 MW and the total electricity load is 61 998 MW·h in the district in recent years. The planning heat load is 422.5 t/h by the year 2012. If the expectation and variance of energy demand are gained through calculating according to Poisson process theory, the stochastic development of energy demand is approximately a normal distribution function. Compares the stochastic prediction result with statistic and planning results, and finds that both the statistics prediction and the planning prediction of district energy load can meet the needs of energy demand load which most likely occurs at different times.
