A Peer-2-Peer Management and Secure Policy of the Energy Internet in Smart Microgrids

A peer-to-peer (P2P) energy trading (ET) scheme has been presented in numerous scenarios within the industrial Internet of Things (IIoT), such as vehicle-to-grid network, microgrids, and energy harvesting network. These scenarios present security and privacy issues because of the lack of trust and transparency in the energy markets. In this article, a secure ET system named energy blockchain (EBC) is proposed in order to overcome the security issues. An EBC is suitable for P2P ET situations in which trusted intermediaries are not needed. Similarly, a credit-based payment method to help eliminate ET delays due to transaction confirmation delays on the EBC is proposed. In addition, an optimal pricing method according to the Stackelberg game has been suggested for credit-based loans. According to a real dataset, security analysis and numerical outcomes indicate that the suggested blockchain and payment layout based on credit are both effective and safe in IIoT.
