Abstract
City Civil load household appliances are mainly urban residents, it has an upward trend year after year, as well as significant seasonal fluctuations in the characteristics and load characteristics of civil with people's normal lives and work of the law are closely related. Commercial load, mainly refers to the commercial sector, lighting, air conditioning, power and other electricity load, covering an area of large and steady demand growth, commercial load equally the characteristics of seasonal fluctuations. While the commercial load in the power load is less than the proportion of industrial load and civilian load, but the commercial load in the lighting category occupied by the power system peak load periods. In addition, the business sector due to increased business activities in the holidays, hours of operation, thus becoming the holidays, that affect an important factor in the power load. Industrial load is used for industrial production of electricity, the proportion of general industrial load in the composition of the primacy of power, it depends not only on industrial users of the work (including equipment utilization, enterprise work-shift, etc.), but also with various sectors of the industry characteristics, seasonal factors, have close ties, the general load is relatively constant. Rural load refers to the rural population and agricultural production of electricity consumption. Such load and industrial load compared to climate, season and other natural conditions, have a great impact, this is determined by the characteristics of agricultural production decisions. Agriculture and electricity load also affected by crop type, farming practices, the impact, but on the power grid, since the concentration of agriculture and electricity load at peak time and the urban-industrial time, the difference, so good for improving the power load rate.
