Energy demand has increased significantly in the recent years due to the emerging of new technologies and industries, in particular in the developing countries. This increase requires much more developed power grid system than the existing traditional ones. Smart grid (SG) offers a potential solution to this problem. Being one of the most needed and complex cyber-physical systems (CPS), SG has been addressed exhaustively by researchers, from different views and aspects. However, energy optimization yet needs much more studying and examination. Therefore, this chapter presents a comprehensive investigation and analysis of the state-of-the-art developments in SG as a CPS with emphasis on energy optimization techniques and challenges. It also surveys the main challenges facing the SG considering CPS factors and the remarkable accomplishments and techniques in addressing these challenges. In addition, the document contrasts between different techniques according to their efficiency, usage, and feasibility. Moreover, this work explores the most effective applications of the SG as a CPS.

Smart Grid is a communication and automatic control capabilities in electric power grid system for improving efficiency, reliability, management, capabilities and security of electric power grid. Routing is important in Smart Grid to send data from one point to another point. Routing in Smart Grid is necessary to search /identify destination point/node for communication and to computer the best available route in the network topology among which the data to be sent during communication. Smart Grid can be a combination of fixed nodes (home appliances, smart meter, control centre, etc.) but the nature of communication between fixed nodes is dynamic due to the switch on/off or the fluctuation in electricity flow. Therefore the fixed nodes can also be disappeared from the network topology in Smart Grid. Existing routing protocols for Smart Grid are based on flooding mechanism. We would like to examine the feasibility of flooding free routing in Smart Grid. Then we will propose a flooding-free routing for Smart.

India’s electrical power system grid also known as the power grid is serving us from a very long time. In this duration, there were no major developments or changes reported in the power grid system. Electrical power consumer demand is increasing drastically and the present grid system is not able to fulfil these emerging requirements. To fulfil the requirements of future power load, we need a modified system which has to be reliable, secure, intelligent and efficient. By converting the power grid into the smart grid will be a promising solution for adopting the above properties. Communication Infrastructure is a major part of the smart grid. The end-user can reduce their expenditure on electricity demand by using smart home appliance, to keep away from the rush hours and also make use of the renewable energy instead from utility, is a great example of deployment of internet of things (IoT) in grid communication. In this paper, we have provided a survey of different communication technology, applications, benefits and challenges in communication infrastructure, spatially IoT.

The smart grid is the aggregation of emerging technologies in both hardware and software along with practices to make the existing power grid more reliable and ultimately more beneficial to consumers. The smart grid concept is associated with the production of electricity from renewable energy sources (RES). For the distant isolated regions, microgrids (MG) with RES are offering a suitable solution for remote and isolated region electrification. The improper sizing would lead to huge investment cost which could have been avoided. The objective of this chapter is to review the state-of-the-art studies on the use of optimization techniques to renewable energy design and sizing. The chapter reviews the optimization techniques employed at different components of the microgrid including the energy sources, storage elements, and converters/inverters with their control systems.

Smart grid (SG) is a next-generation grid which is responsible for changing the lifestyle of modern society. It avoids the shortcomings of traditional grids by incorporating new technologies in the existing grids. In this paper, we have presented SG in detail with its features, advantages, and architecture. The demand side management techniques used in smart grid are also presented. With the wide usage of domestic appliances in homes, the residential users need to optimize the appliance scheduling strategies. These strategies require the consumer’s flexibility and awareness. Optimization of the power demand for home appliances is a challenge faced by both utility and consumers, particularly during peak hours when the consumption of electricity is on the higher side. Therefore, utility companies have introduced various time-varying incentives and dynamic pricing schemes that provides different rates of electricity at different times depending on consumption. The residential appliance scheduling problem (RASP) is the problem of scheduling appliances at appropriate periods considering the pricing schemes. The objectives of RASP are to minimize electricity cost (EC) of users, minimize the peak-to-average ratio (PAR), and improve the user satisfaction (US) level by minimizing waiting times for the appliances. Various methods have been studied for energy management in residential sectors which encourage the users to schedule their appliances efficiently. This paper aims to give an overview of optimization techniques for residential appliance scheduling. The reviewed studies are classified into classical techniques, heuristic approaches, and meta-heuristic algorithms. Based on this overview, the future research directions are proposed.

Abstract Due to the widespread of new technologies, the modern electric power system has become much more complex and uncertain. The Integration of technologies in the electric power system has increased the exposure of cyber threats and correlative susceptibilities from malicious cyber-attacks. To better address these cyber risks and minimize the effects of the power system outage, this research identifies the potential causes and mitigation techniques for the smart grid (SG) and assesses the overall cyber resilience of smart grid systems using a Bayesian network approach. Bayesian network is a powerful analytical tool predominantly used in risk, reliability, and resilience assessment under uncertainty. The quantification of the model is examined, and the results are analyzed through different advanced techniques such as predictive inference reasoning and sensitivity analysis. Different scenarios have been developed and analyzed to identify critical variables that are susceptible to the cyber resilience of a smart grid system of systems. Insight drawn from these analyses suggests that overall cyber resilience of the SG system of systems is dependent upon the status of identified factors, and more attention should be directed towards developing the countermeasures against access domain vulnerability. The research also shows the efficacy of a Bayesian network to assess and enhance the overall cyber resilience of the smart grid system of systems.

Energy is an indispensable factor for the economic growth and development of a country. Energy consumption is rapidly increasing worldwide. To fulfill this energy demand, alternative energy sources and efficient utilization are being explored. Various sources of renewable energy and their efficient utilization are comprehensively reviewed and presented in this paper. Also the trend in research and development for the technological advancement of energy utilization and smart grid system for future energy security is presented. Results show that renewable energy resources are becoming more prevalent as more electricity generation becomes necessary and could provide half of the total energy demands by 2050. To satisfy the future energy demand, the smart grid system can be used as an efficient system for energy security. The smart grid also delivers significant environmental benefits by conservation and renewable generation integration.

A Smart Grid (SG) generally refers to a modernized power grid system that incorporates Infor­ mation and Communications Technologies (ICT) so that a two way communication between the grid system (utility) and power users ensures power supply efficiency and optimization to the users. In a way, an SG is an evolved version of legacy power grid systems that manages electricity de­ mand in a sustainable, reliable and economic manner, built on advanced infrastructure and tuned to facilitate the integration of all involved. The provisioning of duplex communication between the utility and itsusers (customers) allows key devicessuch as SMs to interact directly with the utility 's control center (CC). SGs are destined for provisioning a cleaner environmental sustainable and renewable energy for the future. Its successes mostly rely on advanced ICT design and architecture. It is imperative that it meets the future data transmission and design performance requirements in terms ofrobustness, reliability, and at the same time ensuring end-to-end data exchanges with min­ imal latencies and losses. The incorporation oflCT, however, results in security and access control challenges, as a result complex network arrangement may be exploited by hackers among other things, access private information and sensitive data, hence the necessity to address vulnerabilities of such systems. Typ­ ical consequences or repercussions of security and access control threats include energy theft by way of altering of SM data. At present, it is cost effective to implement the ICT related infrastruc­ ture on the currently unused power line spectrum (i.e. above 50Hz) hence in this work, Power Line Communication (PLC) is elected for provisioning this platform. As such, PLC implementation shall imply the digital communication in power lines concurrently with electrical power transmission and ensuring uninterruption of either of the services, as well as guaranteed efficiency. We address approaches to increasing the data rate of transmission and re­ duction of bit error rates. That will enhance the performance of PLC and redevelopment ofreliable JCT without additional cost to the existing infrastructure of electrical grids. We also address secu­ rity and access control by implementing Advanced Encryption Standard (AES) protocol to secure SG related data in our proposed security and access control framework. Results show that the sys­ tem has low computational requirements, minimal latency and as well ensures confidentiality and integrity. The simulation is run on a combined MATLAB/ OPNET platform.
