Belastningskurvan

Belastningskurvan, often translated as load curve or demand curve, is a graphical representation of the power demand on an electrical system over a period of time, typically 24 hours. It illustrates how the electricity consumption fluctuates throughout the day, week, or year. The vertical axis of the curve shows the power demand in kilowatts or megawatts, while the horizontal axis represents time.

The shape of the belastningskurve provides crucial information for electricity providers. It highlights periods of peak demand, when consumption is highest, and periods of minimum demand, often referred to as base load. Understanding these patterns is essential for efficient power generation and distribution. Utilities can use the load curve to forecast future demand, optimize the operation of power plants, and manage the grid effectively.

Key features of a typical belastningskurve include a rise in demand during the morning as people wake up and start their daily activities, a peak in the evening when residential and commercial activities often coincide, and a significant drop during the night when consumption is lowest. Seasonal variations also influence the load curve, with higher demand in summer due to air conditioning and in winter due to heating. Analyzing historical load data helps in planning for future infrastructure needs and ensuring a stable and reliable electricity supply.
