A collaborative management mechanism for UPIDs operation against MAD attacks

With the user-side heterogeneous power IoT devices (UPIDs) integrating into power systems, the cyber security of UPIDs brings a hidden danger to the power system due to their high-wattage terminals, and there is a new attack plan that can leverage such terminal botnets in order to manipulate the power demand, referred to as Manipulation of demand (MAD) attacks. To this end, a collaborative management mechanism for UPIDs operation is needed to mitigate the malicious impact of MAD attacks. Firstly, taking into account the vulnerability of the deployed cyber security defense measures, a cyber security vulnerability assessment method for UPIDs is proposed, which provides a criterion for the security control strategy. Besides, the security control strategy is constructed considering the security factors in the cyber domain and the physical domain, ensuring the reliability of power systems. The effectiveness of the proposed collaborative management mechanism is verified by simulations on a modified IEEE 14-bus system, highlighting the importance of the active defense scheme against MAD attacks.
