The smart grid is a complex system consisting of interdependent power grid and information and communication (ICT) components. Complex systems have different properties than simple networks and give raise to new risks and failure types. In this paper, we study the dependencies in smart grid and the influence ICT may have on the dependability. We start with giving a categorization of the smart g...

The smart grid is envisioned to be a completely automated infrastructure that will require little or no human intervention to address growing demands of the grid consumers. This is made possible by the integration of latest information and communications technologies (ICT) into the power grid. The various sensors installed in the smart grid have the capability to report back information related...

One of the most distinguished challenges in studying the aftermath of cyber attacks in smart grid lies in data-centric threats, which refer to cyber attacks aimed at gaining advantage or sabotage the infrastructure by manipulating the data exchanged in the underlying communication network. Even though such attacks are critical by itself in the information network, they will result in more serio...

The power system of the future is an intelligent grid capable of a number of functionalities. These functionalities will enable the power system to exhibit behaviours that enhance the reliability and security of the power system. This modern power system is called the smart grid. In order to ensure proper operation of the smart grid, it is important that its constituent parts operate satisfacto...

Simulation of smart grid technologies requires a fundamentally new approach to integrated modeling of power systems, energy markets, building technologies, and the plethora of other resources and assets that are becoming part of modern electricity production, delivery, and consumption systems. As a result, the US Department of Energy’s Office of Electricity commissioned the development of a new...

Future Smart Grid systems will intelligently monitor and control energy flows in order to improve the efficiency and reliability of power delivery. This monitoring and control requires low-delay, highly reliable communication between customers, local utilities and regional utilities. A vital part of future Smart Grids is the two-way communication links between smart meters at the customer sites...

The paper discusses power and especially voltage quality issues in the smart grid environment. New demands that are facing the distribution network, by introducing the concept of intelligent networks (Smart Grids), are presented. Some examples of non-compliance of laws and practices in Serbia are presented as well, as the illustration of lack of strategic planning in the field. Through several ...

The smart shower is an intelligent device that saves the water during the shower. It uses the indicator lamps that inform the user of the amount of the water. Like the traffic signal it has three sets of lamps, green, yellow and red, each indicating the amount of time spent. This device brain is the Siemens Logo PLC.

Smart grids enhance power grids by integrating electronic equipment, communication systems and computational tools. In a smart grid, consumers can insert energy into the power grid. We propose a new energy management system (called RLbEMS) that autonomously defines a policy for selling or storing energy surplus in smart homes. This policy is achieved through Batch Reinforcement Learning with hi...

This paper describes the concept and characteristics of smart grid distribution systems, basic difference between conventional and smart grid distribution systems, functional management and reliability evaluation of smart grid distribution systems. In smart grid distribution system, remotely controlled high rated power electronic switches are used in the place of normal disconnecting switches o...
