Abstract
In concern of energy trilemma such as energy security, energy equity, and environmental sustainability, the electric infrastructures are significantly developing the manifold avenues for decentralization, decarbonization, and digitalization. Over the years, the growth of decentralized power systems using distributed energy resources is increasing rapidly, bringing new prospects for local energy trading concerning economic and control operations in a single framework called transactive energy (TE). However, the continuity of power supply after high-disruptive events has remained a potential challenge for the energy market operator. Thus, to triumph over the challenges, this paper proposes a novel TE framework with resiliency consideration. On the other hand, cyber-attacks are an increasing concern, which impacts the digital platform, such as energy digitization. Considering this, homomorphic Blockchain technology is applied to secure the TE platform against cyber-attacks. To show the leveraging capabilities, this paper considers various case studies in the wake of high-disruptive events such as microgrid outage conditions and cyber-attack. The result shows that the proposed TE framework enhances the microgrid benefit and guarantees optimal trading performance. In addition, empowering Blockchain realizes that the security of the system is vital for the TE system when it faces data tampering or any external attacks. The effectiveness and feasibility of the proposed system are evaluated by cost, benefit, and probability of success.
