“…The various statistical Spatio-temporal methods were applied to detect FDIAs in smart grid. The procedures are leveraged the datum co-linearity which occur in the AMI measurements of the electrical power grid to prepare anticipation for the AMI observations of the grid, attaining to rapidly diagnose the presence of "bad data"; besides, a plan for FDIAs with several adversaries and an alone smart grid defender were presented in reference [31]. Two-game schemes have been investigated to consider the interplays among the attackers and the defender.…”

Due to the simultaneous development of DC-microgrids (DC-MGs) and the use of intelligent control, monitoring and operation methods, as well as their structure, these networks can be threatened by various cyber-attacks. Overall, a typical smart DC-MG includes battery, supercapacitors and power electronic devices, fuel cell, solar Photovoltaic (PV) systems, and loads such as smart homes, plug-in hybrid electrical vehicle (PHEV), smart sensors and network communication like fiber cable or wireless to send and receive data. Given these issues, cyber-attack detection and securing data exchanged in smart DC-MGs like CPS has been considered by experts as a significant subject in recent years. In this study, in order to detect false data injection attacks (FDIAs) in a MG system, Hilbert-Huang transform methodology along with blockchain-based ledger technology is used for enhancing the security in the smart DC-MGs with analyzing the voltage and current signals in smart sensors and controllers by extracting the signal details. Results of simulation on the different cases are considered with the objective of verifying the efficacy of the proposed model. The results offer that the suggested model can provide a more precise and robust detection mechanism against FDIA and improve the security of data exchanging in a smart DC-MG.

This paper presents an energy plan for harnessing electrical power from hybrid energy resources, including biomass and solid waste, through hybrid technologies for microgrid development to overcome the current energy crisis and provide future sustainable electricity pathways for a developing country. Biomass and solid waste were collected from different dumping sites in Pakistan and were tested for their calorific value, which was found to be 6519Kcal/Kg. The total power was calculated based on this calorific value and it was found that there is a potential of total 11,989.5GW of power generation. Thus, hybrid energy resources are suitable for harnessing electrical energy through hybrid technologies. Different hybrid systems were examined for these resources and the gasification technique is finally proposed as the most suitable method for producing energy from biomass and solid waste resources in Pakistan. This technique is also found to be economically feasible for processing all kinds of waste.

“…The lack of effective protection strategy and the nature of DC faults make the protection of DC Microgrids a significant challenge for DC Microgrid implementations [10]. In the DC systems, due to the high rate and amplitude of fault current, the low cable impedance, the presence of power converters, and lack of zero-crossing point, the detection of a fault in the DC Microgrids is difficult [11]. Therefore, designing a fast, selective, and reliable protection strategy for reducing the cost and risk of DC Microgrids is crucial.…”

DC Microgrid protection is one of the challenges in utilizing DC Microgrids. This paper offers a protection scheme for DC Microgrids with ring configuration by using local intelligent electronic devices. This method is based on monitoring the distribution-sensitive poverty index, which is calculated by using the current in different sample times. Moreover, this protection method only uses the local data at the intelligent electronic devices without using any communication links; thus, it increases the reliability and also decreases the cost of the protection system. In addition, the proposed scheme is capable of detecting the high impedance faults within the DC Microgrid lines. The effectiveness of the proposed strategy is demonstrated by using simulations in different scenarios. Simulation results indicate that the proposed method can detect both low and high impedance faults within several milliseconds, and the comparison with other fault detection methods reveals the superiority of the proposed strategy.
