This paper presents a comparative study between Active Disturbance Rejection Control (ADRC) based Load Frequency Control (LFC) and proportional-integral-derivative (PID) based LFC. Both, single-area power system and multi-area power system have been considered where area control error (ACE) has been regulated in the presence of uncertainties in system dynamics and external disturbances. The ADRC proves...
Active disturbance rejection control (ADRC) has gained significant attraction due to its simple tuning method and robustness against process parameter variations, whether the plant is linear or non-linear, time-varying or time-invariant. In load frequency control, the use of ADRC is proposed to regulate the area control error, frequency error and tie-line error in the presence of internal dynamics...
Control of active power and frequency in a power system is referred to as load frequency control (LFC). A linear combination of tie line power between interconnected system and frequency deviations, defined as area control error (ACE), is regulated to zero by LFC such that frequency and tie-line power errors are forced to zeros and a balance is achieved between generation and load. This paper presents...
This paper presents an Active Disturbance Rejection Control (ADRC) based robust decentralized load frequency controller for Bangladesh Power System (BPS) that maintains frequency and tie-line power flows to specified values in the presence of physical constraints and model uncertainties. Feedback connection from specific load bus to specific controller is also proposed. Simulation results show that...
