This paper presents FraSEE, a framework whose goal is to increase the energy efficiency (EE) of smart grid applications, specifically for the Power Quality (PQ) application domain. The key idea is to use a Wireless Sensor and Actuator Network (WSAN) and decentralize the decision processes of such applications among WSAN nodes through information fusion. Experiments assessed FraSEE effectiveness in...
The increasing demand for highly sophisticated cloud services and the consequent worldwide increase in the number of data centers (DC), make the need for energy efficient operation of DCs more actual than ever. Additionally, in the context of smart city and smart grid integration, flexible DCs can play a key role toward acting as grid-stabilization factors. In this paper, a review of the available...
Control systems in building automation influence achieved energy efficiency of the buildings. One of the measures that is used by control systems is electric energy usage. The paper deals with the subject of automatic data acquisition of electricity consumption not only for the purpose of accounting the energy consumers, but also for using these data in building control systems in order to achieve...
Electricity consumption has increased substantially over the last decade. According to the Gulf Research Center (2013), residential sector represents the largest portion of electricity consumption (about 50%) in the Gulf Cooperation Council (GCC) region, due to substantial growth of electrical residential appliances. Therefore, we present a novel online smart residential load management system that...
Demand side management is considered as the next evolution of smart grid technology, it can adjust the time and the quantity of the electricity usage either by shifting the demand during the peak hours or by moving the time of energy use to off-peak periods. The objective of this paper is to develop an efficient load side management strategy for photovoltaic-wind hybrid energy system for an isolated...
The rapid increase in energy demand requires effective measures to plan and optimize resources for efficient energy production within a smart grid environment. This paper presents a data driven approach to forecasting heat load for multi-family apartment buildings in a District Heating System (DHS). The forecasting model is built using six and eleven weeks of data from five building substations. The...
A level European countries, Italy counts with the higher number of smart meters deployment in its net electricity. Nowadays, ENEL, Italy's largest electric utility has installed 40 million smart meters based on PLC with an innovative remote management system called Telegestore. Smart metering based on PLC is the natural backbone and the first step toward Smart Grid. Nevertheless, the technology is...
The main objectives of the Smart Grid is to ensure a more resilient infrastructure, reliable power delivery, reduced carbon footprint, protection against technical and non-technical losses, and elevate customer satisfaction. This is achieved through the implementing of new technologies such as Distributed Energy Resources, Smart Metering, Bi-Directional Power Flow, Demand Side Management, Distributed...
A power allocation algorithm for the orthogonal frequency division multiplexing (OFDM) system under the real-time price (RTP) of smart grid is considered, where RTP is related to the energy consumed by the base station. The optimization objective maximizes the economic energy efficiency (EE) utility, and the barrier method with damped Newton method is used to solve the optimization problem. Simulation...
Data centers are a large energy user, accounting for an increasing portion, currently over 1.5% of the worlds electricity consumption. They have the potential to provide a significant Demand Response to the power system, by reducing and consolidating their server loads or increasing temperature set points. Data centers may also move their Information Technology (IT) workload geographically to provide...
Demand Side Management (DSM) as a main component of Smart Grid paradigm, provides great opportunities to increase system reliability and efficiency. This paper develops a new method to model the inherent flexibility of water pumping process in drinking water storage facilities to be used in grid balance and maximize the efficiency of hydroelectric power generation. Fluctuating nature of system demand...
The provisions of UE directives adopted by countries of the European Union oblige EU member states to improve energy efficiency and reduce the level of harmful substances released into the atmosphere. The provisions are defined as energy packets, especially the directive Energy Performance of Buildings require of new buildings after 2020 nearly zero-energy consumption from the viewpoint of the distribution...
This paper presents architecture for smart grid elements and concepts modeling. We choose the Multi-Agent Systems (MAS) technology, because it meets this new generation network's requirements and objectives. There is a need of potential redesign and jeopardize of the traditional electrical networks. As several huge blackouts happened this last decade, they are being gradually left in favor of smart...
The building sector is a major energy consumer and CO2 emitter, being responsible for approximately 40% of the total consumption in the EU. Active demand side participation of electricity customers is seen as crucial in the management and reduction of the building sector's CO2 emissions. However, today's electricity markets are often lacking strong incentives for active demand side participation....
The growing demand for electricity has forced towards the implementation of smart grid where the various participants share and communicate power system data to trade electricity and control electrical power systems. Though service orientation acts as a promising technology to solve integration problems among these domains, data exchange and information interpretation are continuing to be challenges...
Recently, ideas like smart cities, smart buildings/homes has been widely used under smart grid concept, which is a new research area that combines power systems and information technology (IT). The basic building block of the smart grid can be considered as “smart home”. Smart grid infrastructure with smart homes will allow to monitor electrical demand of a city or a residential customer and to achieve...
Some customers; like hospitals, fire departments and traffic control; have special needs related to power supply. Sooner the power outage diagnostic, sooner the maintenance and the time without energy is reduced. Power quality problems can disturb traffic semaphores controls and the utilities do not have a real-time monitoring system for the low-voltage grid. An UPS with batteries was developed, for...
The main objective in of this paper is to emphasize the importance of Smart Grid as a potential source for reducing the emissions of greenhouse gases in the atmosphere, through mechanisms that may directly to the energy efficiency and in the integration of renewable energy generation, making a short quantification of the benefits provided by the reduction of these gases and therefore a reduction in...
Rapidly rising energy costs and increasingly rigid environmental standards have led to an emerging trend of addressing the “energy efficiency” aspect of mobile cellular networks. Cognitive heterogeneous mobile networks are considered as important techniques to improve the energy efficiency. However, most existing works do not consider the power grid, which provides electricity to cellular networks...
This paper considers an increasing problem in the consumer end of the electrical grid. The ongoing change from constant impedance loads towards constant power characteristics in new household electrical appliances may affect the network voltage stability. Can the smart grid development disarm this potential threat? This work points out an important target for load modeling in network simulation.
