Abstract
Industrial Internet of Things (IIoT) has been defined as an architecture that uses the Internet of Things (IoT) and cloud computing to facilitate distributed control of modern industrial systems like AC smart microgrids (MGs). This paper proposes a novel secure energy policy and load sharing approach for renewable MGs for independent utilization of off-grid MGs with power electronic jointing (PEJ) on the basis of master-slave (M-S) which is formed in the IIoT environment. Assume that computations for system dispatch are performed by an upper layer however a lower layer calculates proper control proceedings for the PEJ. A decentralized multi-agent system (MAS) realizes the upper layer of intelligent control on the basis of communication. The layer has 2 control mechanisms: economic dispatch and MAS power balance control. Numerous operating, controlling, and planning to be in the energy industry pay special attention to Blockchain technology. In addition to allowing a common and distributed database, Blockchain technology (B.CT) enables safe, automated, transparent, and economic operations in power distribution systems. If a hacker manipulates and alters the data exchanged between agents, it will result in disrupting system performance in terms of economy and stability MG voltage profile, load distribution, optimized parameters including cost, environmental pollution, and unit output. Therefore, it is necessary to maintain the cyber security of AC smart MG and increase the security of data measured in the sensors and the transaction data between agents. In this paper, B.CT is presented to secure the exchanged data against malicious cyber-attacks in an AC smart MG whose control layers are M-S organized. The simulated system consists of the MG with several distributed generation units that examine cyber-attack points and then compare the results in normal mode and cyber-attack mode and B.CT is presented to increase the cyber security of AC smart MG.
