The Smart Power Grid: Today and Tomorrow
The Smart Grid, considered as the upcoming power grid, uses bidirectional flows of power and information to create a widely distributed automated and robotized energy delivery network. Power plays a critical role for social, economic and industrial development. As a result of built-up simplification, especially in agricultural and economical activities, the energy demand has increased rapidly in developed nations. Production and practice of energy has nonstop brunt on modern power grid. In this scenario energy management is a tough assignment to tackle because load is dynamic and we don’t have control over it. Renewable or undepleted energy assets have immense applications and bang in existing electric power system circumstances. For example it gives contamination free (green) energy which is environment and user amusing. It is cost efficient, it uses ordinary assets for its production and so do not devastate any coal, gas etc. There are many affectations to empower energy yield. As current smart grid is complex and non linear in operation and design, it utilizes an upgraded technique that gives greatest productivity with minimum sum input. Keywords: Smart Grid (SG),
Smart Grid for a Sustainable Future
Smart Grid and Renewable Energy, 2013
Advances in micro-electro-mechanical systems (MEMS) and information communication technology (ICT) have facilitated the development of integrated electrical power systems for the future. A recent major issue is the need for a healthy and sustainable power transmission and distribution system that is smart, reliable and climate-friendly. Therefore, at the start of the 21 st Century, Government, utilities and research communities are working jointly to develop an intelligent grid system, which is now known as a smart grid. Smart grid will provide highly consistent and reliable services, efficient energy management practices, smart metering integration, automation and precision decision support systems and self healing facilities. Smart grid will also bring benefits of seamless integration of renewable energy sources to the power networks. This paper focuses on the benefits and probable deployment issues of smart grid technology for a sustainable future both nationally and internationally. This paper also investigates the ongoing major research programs in Europe, America and Australia for smart grid and the associated enabling technologies. Finally, this study explores the prospects and characteristics of renewable energy sources with possible deployment integration issues to develop a clean energy smart grid technology for an intelligent power system.
Challenges in Implementing Smart Grid in Power Systems
International Journal of Advanced Engineering and Nano Technology (IJAENT), 2015
Electricity, considered by most to be energy, is actually an energy currency. Power collected from a variety of sources, such as falling water, burning fuel, wind and solar is used to create electricity for delivery to customers. Electricity has proven to be a convenient and efficient means of delivering energy. Electricity is delivered at the speed of light and is consumed the instant it is created. There is no means to store electricity without converting it to another form of energy. As a result, the demand for power, driven by users, must match the supply of power from the available sources (e.g. generators and energy storage devices) at all times. As the Smart Grid continues to evolve, and demandside management, which is available today, builds on its growing reputation as a cost-effective way for industrial users to manage energy usage and costs, buy-in from both residential and industrial consumers will become simpler. In this paper we have discussed use of ICT in Smart Grid, concept of Smart Grid, Goals and Objectives of Smart Grid, Characteristics of Smart Grid, Smart Grid Applications and Services, and Challenges in Smart Grid.

INTRODUCTION Smart grid (SG) technologies are vital to meet world's vast and growing electricity needs. Smart grids (SGs) are transforming the traditional way of meeting the electricity demand and providing the way towards an environmentally friendly, reliable and resilient power grid. Micro grids operate at the distribution level, and they are natural innovation zones for the Smart Grid (SG) because they have experimentation scalability and flexibility, and delivers power is a local area. SG contains protection against the cyber attacks, interoperability and designed for pricing in real-time [1]. Super grid is a high voltage DC transmission and capacity to minimize losses and enhance reliability. MGs operates as a standalone or as a grid-connected system. Microgrid (MG) technology is not equipped with automation and communication support. Further work is required to enhance self-healing, reconfigurable, adaptive and predictive capability. MG includes special purpose inverters enabling it to link to the legacy grid and contains special purpose filters build to overcome issues with harmonics, while improving power quality and efficiency [2]. Various characteristics of SG include optimizing the asset utilization and efficient operation is presented in [3]. Increased renewable power penetration, electricity markets participation throughout the world will realize new opportunities for the cost-effective smart grids controls and energy storage at all scales. These changes, coupled with increased consumer awareness and participation will lead to a new paradigm in energy system analysis that must also be accounted for energy security, stability and reliability. The SG will incorporates new networking technology, including controls and sensors, from this the electricity can be monitored in real time and can be made automatic changes which will reduce the energy waste [4].

Rising energy costs, losses in the present-day electricity grid, risks from nuclear power generation, and global environmental changes are motivating a transformation of the conventional ways of generating electricity. Globally, there is a desire to rely more on renewable energy resources (RERs) for electricity generation. RERs reduce green house gas emissions and may have economic benefits, e.g., through applying demand side management with dynamic pricing so as to shift loads from fossil fuel-based generators to RERs. The electricity grid is presently evolving towards an intelligent grid, the so-called smart grid (SG). One of the major goals of the future SG is to move towards 100% electricity generation from RERs, i.e., towards a 100% renewable grid. However, the disparate, intermittent, and typically widely geographically distributed nature of RERs complicates the integration of RERs into the SG. Moreover, individual RERs have generally lower capacity than conventional fossil-fuel plants, and these RERs are based on a wide spectrum of different technologies. In this article, we give an overview of recent efforts that aim to integrate RERs into the SG. We outline the integration of RERs into the SG along with their supporting communication networks. We also discuss ongoing projects that seek to integrate RERs into the SG around the globe. Finally, we outline future research directions on integrating RERs into the SG. Index Terms-Renewable energy resources (RERs), Distributed energy resources (DERs), Advanced metering infrastructure (AMI), Communication architecture, Smart grid (SG). I. INTRODUCTION A. Motivation: Need for Integration of Renewable Energy Resources with Smart Grid Nowadays, there is a high demand for renewable energy and this demand is increasing due to rising energy cost and global environmental changes. The existing power grid relies heavily on conventional fossil fuel-based electricity generation units. Moving electrical energy from these generation units

RENEWABLE ENERGY AND SMART GRID SYSTEM, 2022
The commonly utilized smart grid technology helps to reduce losses and increase system stability. It promotes dependability, effectiveness, and efficient management of the electrical energy supply. Although it has been a popular issue in recent papers, academics still don't fully comprehend it. Since this subject requires a broad foundation, the goal of this review effort is to enlighten and assist beginning researchers. It is difficult for the current electric transmission and distribution networks to deliver resiliency in performance, dependability in service, and real-time data. While conventional networks lack the flexibility to interact with renewable energy generators or microgrids, the smart grid is a potential network maneuver to stabilize the system whenever any disruptions break out employing distributed renewable energy producers. This thorough effort is done to map earlier contributions logically, and it includes the requirements, features, and principles that are offered to help readers who are interested in the creation of smart grids.
