terhelésgörbe

A terhelésgörbe, or load curve, is a graphical representation of the electrical power demand on a system over a specific period. Typically, this period is 24 hours, showing the power consumption from midnight to midnight. The horizontal axis represents time, while the vertical axis shows the instantaneous power demand, usually measured in megawatts (MW) or kilowatts (kW).

Terhelésgörbes are crucial for electricity grid operators and power generation companies. They help in understanding the daily, weekly, and seasonal patterns of electricity usage. The curve generally exhibits a characteristic shape: lower demand during the night, a rise in the morning as people wake up and begin activities, a peak in the late afternoon or early evening when industrial and residential loads are highest, and then a decline as the evening progresses and people go to sleep.

Analyzing terhelésgörbes allows for accurate forecasting of future electricity demand. This is vital for efficient power generation planning, ensuring that enough power is available to meet demand at all times while avoiding the costly overproduction of electricity. It also aids in the management of power plant operations, scheduling maintenance, and optimizing the dispatch of different types of power sources, such as baseload plants, peaking plants, and renewable energy sources, whose availability often fluctuates. Different types of loads, like residential, commercial, and industrial, contribute to the overall shape of the terhelésgörbe, and understanding these contributions is key to effective grid management.
