This paper presents the solutions provided by ABB Station Service Voltage Transformer (SSVT) to be an alternative power source in various kinds of substation applications. A SSVT is a hybrid type of instrument transformer which incorporates features of a high voltage inductive voltage transformer with that of a distribution transformer to offer a compact and reliable power source. Based on different...
A decarbonized society involves people living and working in low-energy and low-emission buildings. An a smart multi-Terminal DC μ-grids interconnecting several autonomous zero-net energy buildings allow the transition to a decarbonized economy, however, involves several challenges. This paper describes the interactions between the intrinsic concepts related to development of a smart multi-terminal...
Advanced Metering Infrastructure (AMI) network is the capillary communication network for smart grid that does not only provide the data collection from each household but also delivers configuration requests from intelligent energy services. However, the smart grid network challenges like heterogeneity, large-scale, and distributed operation must be solved for reliable and stable smart grid services...
Reliability is one of the most important requirements for smart grid communications. Cooperative communications have been considered for smart grid communications to enhance the transmission reliability. In this paper, we propose reduced-complexity algorithms to minimize the total transmission power of cooperative communications while guaranteeing transmission reliability of the smart grid neighbourhood...
Advanced Metering Infrastructure (AMI) is one of the most important components of smart grid (SG) which aggregates data from smart meters (SMs) and sends the collected data to the utility center (UC) to be analyzed and stored. In traditional centralized AMI architecture, there is one meter data management system to process all gathered information in the UC, therefore, by increasing the number of...
Smart meters are responsible for keeping track of user energy consumption in a smart grid infrastructure. This data is periodically sent to one or more data aggregation points (DAPs), typically via wireless communication. Efficiently choosing the best positions for installing DAPs is an NP-Complete problem and therefore a difficult task, specially in big cities that may contain thousands of smart...
Energy demand is increasing ubiquitously, and as cities grow larger they become more industrialized and more connected. Therefore new energy solutions that take advantage of today's smart cities capabilities (like intelligent infrastructure, sensors, actuators and citizen engagement) should be deployed. This work studies some aspects of the energy markets as part of the solution to the efficient procurement...
This paper presents a methodology to provide information for decision-making toward the real-time quantification of financial losses in distribution systems. Using multi-criteria analysis and data from an automated measurement system, the proposed method includes the evaluation of main factors that impact on power quality and reliability indexes. Additionally, aspects related to economic issues and...
Sustainability of microgrids depends on a successful business model, enabling technology, and regulation policies. Technical challenges are still significant, but they can be divided and solved in diverse levels with application of existing technology in several ways. However, the regulatory context is vital to incentive microgrids integration into the electricity market. This article aims to explore...
Conventional grid has been transformed to more efficient grid by included several technology inside, named as a smart grid. This presenting paper discussed the characteristics of smart grid that will provide the benefits in six main area; reliability, economics, efficiency, environmental, security and safety. The stakeholder of the selected country in order to build a smart grid also been discussed...
In this paper some issues related to the Brazilians' regulatory context for microgrids insertion were analyzed. Among various issues, those associated to the fixed minimum billable amount and to the conversion of energy credits generated from net metering in different tariffs were assessed. It is presented a suggested solution for the modification of credit conversion due to generation and consumption...
One of the most challenging aspects related to smart grids refers to solutions and features that add the ability to prevent outage occurrences as well as to promote self-recovery after disturbance, isolating defects and restoring the power system through alternatives routes. The approaches related to Self-Healing in fault detection, system restoring, adaptability, reliability, security, sustainability,...
Companies distributing electricity in the world have sought to enhance the operation of their networks in order to minimize the impact of supply disruptions. Nowadays, with the rise of the Smart Grid concept, the insertion of sophisticated features in the distribution of electric energy has become a reality. This article aims to describe the current situation of the implementation of smart grids by...
Smart Grid in Uruguay has a legal framework defined by the main company of generation, transmission, distribution and marketing of energy in the country: UTE. The Transmission Area defined a development model 2015―2025 whose strategic objectives are: Optimization of Transmission Network, Optimization of the Operation Process, Avoid Collapses and Contribute to the Optimization of Generation through...
The evolution towards smart distribution grids requires distributed intelligence and sophisticated information and communication technology (ICT) with distributed intelligent devices to be spread along the power system. ICT devices will be not a simple add-on of the electrical system, but their availability and efficiency will be essential to the operation of the entire power distribution system as...
Smart grid technology promises to prepare today's power systems for the challenges of the future by extensive integration of information and communication technology (ICT). One key aspect is the control paradigm which will have to be shifted from completely centralized control systems to more dezentralized concepts in order to adapt to the distributed nature of smart grids. Multi-agent systems (MAS)...
Nowadays, there is growing interest towards the area of building integrated photovoltaic (BIPV) systems and PV microgrids (MGs) in the field of power generation and distribution systems. This is mainly due to the higher adaptability and compatibility of these systems with preplanned sustainable development strategies in the most urban areas. The quiet operating process and movement free characteristic...
Traditional power grids lack an appropriate infrastructure to link the involved stakeholders and domains for balancing energy demand and supply. The transmission infrastructure is hierarchically oriented with active bulk generators and passive consumers. Therefore, a bidirectional communication system is needed, which is an essential component of the future smart grid. However, a set of requirements...
This paper presents a methodology for reconfiguration of distribution networks in normal operation and considering the inclusion of distributed generation sources. As a relevant contribution, this work proposes an adaption on the use of AHP (Analytical Hierarchy Process) and on the heuristic search with distributed generation (DG) connected to the grid. It is also presented an analysis of load and...
The Distribution System is the physical interface between the utility and consumers. In order to ensure the reliability in the power supply, a good expansion and operation planning is required. Moreover, the planning of system is important to the optimization of the investments made by the utilities. In this sense, the diagnostic of the distribution system under study is essential to establish appropriate...
