电力负荷预算（Power load budget） Power load budget.Txt iron rice bowls true meaning is not to eat a lifetime in a place, but a lifetime to eat everywhere. It is a piece of shit, also have met shikelang day. So you dont have to worry too much about yourself today. The second chapter is power load budget sixth section maximum load power forecast method Maximum load power, or peak load, can be broadly divided into the following three categories: Direct prediction method; electric load rate method; load curve method. Some of the forecasting methods discussed above can predict the maximum load of the power system directly according to the load data of the system. However, in general, the maximum load of the power system is usually calculated before the electricity consumption is forecasted, that is to say, the so-called electricity load rate method is adopted. This is because the electricity consumption data, whether it is power grid or user, is relatively stable in the year after year change. Its data is easy to statistics and complete, and the change rule is obvious, and it is easy to construct or establish prediction model. But the distribution of peak load is in power on the time coordinate, randomicity, so if the various forecasting methods discussed above to directly predict the peak load larger error will be produced, so, in the long term peak load forecasting power load rate method are selected. Lets introduce some conventional methods for predicting the maximum load power. According to the different prediction angles, the maximum load forecasting can be divided into the comprehensive maximum load forecasting of the power system (user side) and the maximum load forecasting of the power generation system (power supply side). Among them, the power system integrated maximum load method, mainly in the following. 1. typical curve superposition method The typical curve load superposition method is to use the typical daily load curve of all kinds of users to carry out the supe
