Observer‐Based Sliding Mode Load Frequency Control of Power Systems under Deception Attack

Abstract: This study investigates the observer-based sliding mode load frequency control for multiarea interconnected power systems under deception attack. By introducing the observer and combining it with the system state equation, the expression of the system error is obtained. A sliding mode surface is proposed to make sure the state of the systems to be stable. Then, the state equation of the system under sliding mode control is derived. The asymptotic stability of the whole system is proved by using the linear matr… Show more

“…In Yang et al (2021), a generalized extended state observer and fractional-order theory based integral sliding mode control strategy were presented to relieve the chattering of frequency deviation and tie-line power deviation. For multiarea interconnected power systems under deception attack, an observer-based event-triggered transmission scheme was proposed to ensure the attacked power system can reach a stable position in Qiao et al (2021). In Ansari et al (2023), for two-area thermal interconnected power system, a novel sliding-mode LFC strategy was designed to achieve better tracking performance.…”

“…Considering time delays and data‐packet losses, a dynamic event triggering defense mechanism against FDIA is developed in [23]. To make sure the state of the systems stable, a sliding mode observer‐based defense method is proposed to control the generator load frequency [24]. Generally, the selection of an LQR feedback matrix depends on the experience of designer.…”

“…However, one can find that the effectiveness of the above methods depends on the assumption that the attack sequence is known. For this reason, some scholars further have proposed defense-based safety mechanism to protect the power system [18][19][20][21][22][23][24]. In [18], an interval state estimation-based defense method against FDIA is proposed by considering the lower-and upper bounds of state variables.…”
