This paper presents the vulnerabilities analyses of KL scheme which is an ID-based authentication scheme for AMI network attached SCADA in smart grid and proposes a security-enhanced authentication scheme which satisfies forward secrecy as well as security requirements introduced in KL scheme and also other existing schemes. The proposed scheme uses MDMS which is the supervising system located in an electrical company as a time-synchronizing server in order to synchronize smart devices at home and conducts authentication between smart meter and smart devices using a new secret value generated by an OTP generator every session. The proposed scheme has forward secrecy, so it increases overall security, but its communication and computation overhead reduce its performance slightly, comparing the existing schemes. Nonetheless, hardware specification and communication bandwidth of smart devices will have better conditions continuously, so the proposed scheme would be a good choice for secure AMI environment.

Supply Capacity

The rapid development of the smart grid brings convenience to human beings. It enables users to know the real-time power supply capacity, the power quality, and the electricity price fluctuation of the grid. However, there are still some threats in the smart grid, which increase all kinds of expenses in the grid and cause great trouble to energy distribution. Among them, the man-made nontechnical loss (NTL) problem is particularly prominent. Recently, there are also some NTL detection programs. However, most of the schemes need huge amounts of supporting data and high labor costs. As a result, the NTL problem has not been well solved. In order to better avoid these risks, problems such as tampering of smart meter energy data, bypassing the smart meter directly connected to the grid, and imbalance between revenue and expenditure of the smart grid are tackled, and the threat scene of NTL is constructed. A hierarchical grid gateway blockchain is proposed and designed, and a new decentralized management MDMS system is constructed. The intelligent contract combined with the elliptic curve encryption technology is used to detect the storage and the acquisition of power data, and the detection of NTL problems is realized. At the same time, it has a certain ability to resist attacks such as replay, monitoring, and tampering. We tested the time consumption and throughput of this method on Hyperledger Fabric. At the same time, eight indexes of other methods proposed in the literature are compared. This method has a good effect.

Cooperative Scheduling

Smart grid integration needs a highly accurate power scheduling to minimizes the losses and efficiently utilize the power supply to minimize the loss. Scheduling of a smart grid interface is monitored based on single or multiple objectives scheduler, where the smart grids are scheduled based on the measured parameters of power dispatch and the consumption model. Wherein, multi objective scheduling results in prominent result, the system is a linear monitoring model, where no previous observations are considered in making present decision. This constraint the accuracy of scheduling. In this paper, a new feedback scheduling operation based on feedback operation is proposed. the approach significantly feedbacks the past parameter variation and leads to an optimal power supply in smart grid interface. The experimental results obtained signifies a optimal improvement in the decision delay and power compensation.

In the recent years, technology make everything to do easier. Home automation is the system otomatization for smart home. This project aims to design an automatic system tool for smart home using arduino mega 2560 as a central controller, easyVR as sound processor, driver relay and power supply. After testing, the result of this project shows a design which able to control electronics at home using audio censor. The result shows that overall function is quite well and need about 2 seconds for activated load.

The double pressures of resources and environment have brought the global power industry into the era of Smart Grid. In order to better promote the development of Demand Response of Smart Grid and to offer new regulation resources for the safe and stable operation of electric power system, OpenADR, the Open Automated Demand Response Communications Specification, has been discussed in detail, which aims at the problems of energy efficiency and the contradiction between power supply and demand. And a design scheme of Auto-DR system which introduces in detail the system architecture and the communications architecture based on OpenADR was proposed to realize the two-way communications between Utilities and end-users, and the problems such as the peak, the gap between supply and demand and the electricity structure management would be consequently solved. This scheme has a certain reference value to the Demand Side Management under the framework of Smart Grid.

Efficiency And Reliability

Smart Grid implementations will certainly increase the quantity, quality and use of information available from advanced sensing, computing and communications hardware as well as software. There is virtually universal agreement that it is necessary to upgrade the electric grid to increase overall system efficiency and reliability. Many technologies currently in use by the grid is outdated and in many cases unreliable. The reliance on old technology leads to inefficient systems, costing unnecessary money to the utilities, consumers and taxpayers. To upgrade the grid and to operate an improved grid will require significant dependence on distributed intelligence and broadband communication capabilities. The access and communications capabilities require the latest in security technology which are reliable for extremely large, wide-area communications networks. This paper discusses features, reasons of development, barriers and their solutions for a smart grid system.
