An approach for an extended market grid operation is introduced in this paper. Therefore a Market System Operator as a new role in the electricity economy is defined and an extended ENTSO-e scheduling system is developed. Additionally a traffic light system for distribution grids is integrated. The special part of renewable energy sources with their specific character is taken into account. The aim...
Smart grid applications aims to employ many optimization and artificial intelligence methods for optimal energy management. Results of these algorithms need to be implemented by power systems in practice. This study presents Time Rate Multiple Pulse Width Modulation (TRM-PWM) methods for multi-source energy mixing for DC microgrids, which is integrating several renewable energy resources. In the paper,...
Global energy consumption has risen drastically. In Brazil, although economic growth in recent years has been underwhelming, the growth rate of energy consumption has steadily risen. At the beginning of 2015 important adjustments were made to the energy tax. Within the state of Santa Catarina, in particular, the National Agency of Electrical Energy of Brazil (ANEEL) approved a readjustment of 43%...
Smart grid as a communication network uses advancedmetering infrastructure architecture to collect the measureddata by smart meters and other devices such as powermeasurement units from different parts of the power grid andanalyzes them for billing and sends the collected data to theutility center for further analyses and being stored. In thispaper, we propose a three-layer aggregation architecture...
The penetration of renewable energy (RE) into existing electricity system is ever increasing from past three decades. The existing electricity grid is not capable enough to handle excess penetration of RE. This is challenging especially due to the variable and intermittent nature of some popular renewable energy sources like wind and solar. In order to handle excess penetration of RE into existing...
The smart grid (SG) is widely acknowledged asthe new solution to be developed to handle distributed network fighting against the increase of renewable energy. Wireless Sensor Networks (WSNs) have been extensively recognized as a promising technology that can improve various aspects of electrical models today as smart grid. Hence, WSNs are well suited for applications based on this type of communication...
This paper focuses on wireless communications between energy prosumers in the smart grid, and explores the application of multiple-input multiple output (MIMO) technology to reduce point-to-point transmission delays, and increase communications reliability. MIMO is a wireless technology for sending and receiving more than one data streams on the same channel at the same time by exploiting multipath...
Smart Grid Technology, a reasonable move in modern Power System, assures coveted resiliency, consistency, and the utmost efficiency of the entire Grid System utilizing renewable energy sources such as solar, wind, geothermal, and ocean energy by integrating on-site generation strategies. Apart from its environmental aspect, the renewable energy based smart grid technology has a broad scope of research,...
Demand response (DR) programs generally is a domineering strength reserve in the upcoming electric power methods. Professional clients, industrial customers, received the key consideration on the precise demand response programs. On the other hand, little clients, like residential customers, provides more the variable answer in most of these functions. The primary purpose of this paper is usually...
The energy policies and environmental issues require novel solutions to generate electricity in a challenging and efficient way. The sustainable and reliable grid operations are related to demand management as well as generation. One of the most important requirements to build smarter grids is including smart metering to the power system. The smart grid is not only considered to provide essential...
Integration of Information and Communication (ICT) technologies with power flow management and control to support varying load demand is the hallmark of advanced power networks such as smart grids. Issues arising due to the complexity of these systems can be potentially solved by designing control-communication algorithms based on the information available at any instant of time. This paper presents...
Conventional resources are replenished day by day and are very limited but the need of electricity is increasing day by day. So in the todays scenario, energy alternatives is in trend to use that not only fulfils the need of the residential consumers but also commercial consumers. To overcome the different problems like interrupted and unreliable supply, high cost of the electricity etc., smart grid...
Prospects of creation of power effective, reliable and environmentally friendly sources of electric power for autonomous systems of power supply of removed consumers on the basis of alternative and renewable generating complexes are considered. The complex analysis of operation features of wind power installations according to modern requirements of the active and adaptive SMART GRID systems is submitted...
Due to the networking expertise, services and technical support of telecommunications operators, Smart Grid (SG) operators prefer telecommunications operators for their communications needs instead of creating private networks. In this paper, the use of Next Generation Networks (NGNs) by telecommunications operators to provide services to transnational SG operators for SG applications is evaluated...
This paper studies a multi-period demand response management problem in the smart grid where multiple utility companies compete among themselves. The user-utility interactions are modeled by a noncooperative game of a Stackelberg type where the interactions among the utility companies are captured through a Nash equilibrium. It is shown that this game has a unique Stackelberg equilibrium at which...
This paper investigates the smart grid communication infrastructure with an upgrade of existing electricity networks and advanced ICT technologies, intelligent devices & system. Considering that the energy utilities have been play an increasingly important role in our modern world, smart grid technology also introduces new security challenges that must be addressed. This paper focuses on the implementation...
In this paper, the interconnection of islanded DC microgrids are discussed. The interconnection increases the power supply reliability since a power shortfall in one of the microgrids can be supplied by the others. The islanded DC microgrids are interconnected through a bi-directional DC-DC converter. A high frequency transformer isolation is used in the converter. For interconnecting more than two...
The diversity, continuous expansion and the large number of smart grid resources increase the complexity of such systems and arise the need to find a new way to manage these resources and, at the same time, reduce the complexity in the control and monitoring operations. Moreover, smart grid Systems are considered critical systems requiring reliable and real time data delivery and an efficient, flexible,...
A smart city consists of several components such as governance, mobility, economy and energy that play a key role in transition towards a sustainable urban life, integrating critical infrastructure and various stakeholders. Smart cities are a logical extension of the smart grid concept and realization of smart cities are tightly connected to the process of modernization of traditional power systems...
