Distributed Reputation-based Strategy for Economic Environmental Dispatch under Cyber Attacks

Abstract

This paper studies a distributed combined economic environmental dispatch problem (CEEDP) of the smart grid. CEEDP aims to minimize the economic costs and also emissions with supply-demand balance and generation constraints. A distributed reputation-based algorithm is proposed to defend against non-colluding and colluding attacks, integrating attack detection, isolation, and restoration strategy. By dynamically updating the reputation value of each generator, the isolation process can intelligently adjust the communication weights among the generator units to isolate the units that are under attack. Finally, simulation examples are given to verify the effectiveness of the proposed strategy.
