Abstract:
The purpose of the study is to assess the effect of meteorological factors on electricity
consumption. The object of the study is the power system of the Astrakhan region. As the initial
data, a sample was compiled of the data of 12 months of 2015 and 2016. One of the main indicators
in planning the work of the energy association and the energy system is the magnitude of the forecasts
of the expected power consumption (electricity and power consumption) as a whole for the
system, groups and individual consumers, the nodes of the electrical scheme. The magnitude of the
forecast of power consumption is a reference indicator for the subsequent planning of energy
balances, power and calculation of electrical regimes. The need for accurate forecasting is due
to technological and economic reasons. Accurate calculations to ensure the optimal distribution
of the load between stations, from an economic point of view, facilitate sales of economically viable
operations for the purchase and sale of electricity. There has been given analysis of energy consumption
depending on temperature changes and the amount of precipitation during the accounting
period. Calculations are made for the deviations of each indicator. The graphs of the dependences
of power consumption on the amount of precipitation and temperature are plotted. For these
dependencies, polynomial equations are compiled. For a constant relationship between power consumption
and the temperature of the calculated correlation coefficients. The correlation coefficient
makes it possible to determine how proportional the variability of the two variables is. Taking into
account the set of meteorological factors makes it possible to increase the effectiveness of the
predicted changes in the energy sector.
Keywords:
power consumption, weather factors, power system, temperature, seasonal changes,
