What is tie line bias control?
The tie-line bias control (TBC) method has been widely used in the load frequency control (LFC) of multi-area interconnected systems. However, it should be questioned whether the conventional TBC can still apply to LFC when considering the complication of structures of power systems.
What is the function of load frequency control on a power system?
In an electric power system, Load Frequency Control (LFC) is a system to maintain reasonably uniform frequency, to divide the load between the generators and to control the tie-line interchange schedules.
What is frequency bias?
Frequency illusion, also known as the Baader–Meinhof phenomenon or frequency bias, is a cognitive bias in which, after noticing something for the first time, there is a tendency to notice it more often, leading someone to believe that it has a high frequency of occurrence.
What is load frequency control in a two area power system and control error?
The load-frequency control (LFC) is used to restore the balance between load and generation in each control area by means of speed control. The main goal of LFC is to minimize the transient deviations and steady state error to zero in advance.
What is the load frequency control?
Load frequency control of an interconnected power system means the interconnection of more than one control area through tie lines. Sudden load variation in any control area of an interconnected power system will lead to both frequency change and tie line power deviation.
What is meant by tie line?
Definition of tie-line : a telephone line that directly connects two or more private branch exchanges.
How do you find the frequency bias?
The minimum Frequency Bias Setting (in absolute value), in accordance with BAL-003 R5 should be calculated as 1% of the entity’s projected peak load. For example, if an entity’s peak load is project to be 30,000 MW, its minimum Frequency Bias Setting would be -300 MW/0.1 Hz (30,000 x 0.01 = 300).
What is Tie Line power?
A tie line is a circuit that connects two or more balancing authorities or transmission zones of an electric system. Being able to accurately model and gather data for tie lines is crucial to PJM’s operational calculations as well as market settlements.
