The recent breakthrough on power grid technologies was promoted by the emergence of phasor measurement units (PMUs), as they provide direct and high-rate data for analyzing and controlling the network. Time becomes critical however, since offsets in the internal clocks of PMUs render their data unreliable. In this context, the present work describes grid-wide implementation of a Precision Time Protocol system to deliver an accurate time reference to PMUs at different power stations. Residual time offsets are modeled as PMU noise, propagating to linear state estimators, and their non-linear counterparts that result from combining PMU and power flow data.

New technologies for controlling power flow in electric networks have been developed in past few years. The new technologies are simpler, more compact and lower cost than the traditional power flow controllers such as phase shifters transformers, HVDC and FACTS devices. Such characteristics make them attractive for a variety of applications in transmission, subtransmission and distribution networks. This paper studies the use of these new power routers to increase transmission capacity and flexibility of the transmission grid, and consequently improve the utilization of the existing assets. A framework developed by Electric Power Research Institute for estimating benefits and cost of smart grid projects are used as a reference to assess the various benefits affecting different stakeholders. Two case studies performed for actual regional transmission networks of the Argentinean electric system are presented.

This paper is concerned with integration of demand response from small loads such as residential small appliance into forward electricity market. We use a simple model and formulate the problem as a dynamic program that maximizes social welfare. We focus particularly in those electric appliances with intertemporal consumption constraint. The satisfaction of end-users from operating them are captured through a utility function, which is also time-correlated. We pursued Lagrange decomposition in order to solve the high complexity problem optimization of the complete system. The main purpose is to optimally schedule a day in advance Local Service Entity's (LSE) procurement and final-users consumption in the forward electricity market.

The Uruguayan electric system will reach 1.160 MW of total power installed from wind farm and solar photo voltaic plants resulting in a penetration factor of 28% in solar and wind energy. Demand-response technology gives significant benefits in systems with high levels of penetration of renewable resources. We have developed a smart-grid concept adapted to the technology available in Uruguay -using the national deploy of One Laptop Per Child program-, in order to teach and implement demand-response system. We have developed a device that focuses on a smart-grid teaching concept that gives students the opportunity to choose when to consume power, suggesting that they do it when a renewable source is able to generate the energy in the grid. For a demand-response system to have significant impact on the electric grid system, citizens must behave responsibly, so teaching children (and their families) how the system works provides an opportunity to enhance the introduce of a national demand-response system. The didactic tool, named aty arandu, was developed as a plug-in for Turtle Bots software, allowing students to explore and learn about energy sources and the responsible use of them. We postulate that students who are in control of their learning are more effective learners [11].

Power systems are undergoing fundamental changes, with emphasis on low-carbon and responsibility on the demand side. This transformation consists on modernization of generation, transmission, distribution and consumer technologies, providing to consumers more participation in managing their energy usage and generation through medias that are part of everyday life, as applications on mobile devices. This paper presents methods for monitoring and controlling the energy consumption and generation using photovoltaic system with energy storage in Smart Grid through a mobile application. It proposes energy consumption's analysis methods, establishment of goal of energy consumption, means to load and storage energy control. The mobile application is presented along with its functional description. Through this application, the costumer may visualize its energy consumption and generation data in a time of use tariff and use this information to support decisions to control its smart plugs and energy storage through schedules.

The increasing use of Distributed Generation (DG) resources, as well as the introduction of Demand Response (DR) resources has motivated significant changes in the context of competitive electricity markets and smart grids. The methodology proposed in this paper aims to allow scheduling the DG and DR programs resources, considering the implementation of distinct approaches for DR programs remuneration, such as, Steps, Quadratic, Constant, Linear and Elastic. This methodology can be used by a Virtual Power Player (VPP) that aggregates and manages small size consumption resources, enabling them to participate in DR programs. Distinct levels of energy/price from external suppliers are considered in the case study that accommodates 4 external suppliers, 66 DG units, and 218 consumers, classified into 6 types of consumers. For each context the aggregator is able to discuss on the adequate remuneration approach.

The Brazilian generation system is based on large plants, usually dams located far from load centers, connected to these transmission lines. However, there is an incentive for the use of renewable energy sources distributed to diversify the energy matrix and reduce environmental impacts. The new regulations reinforce this incentive also including the application of distributed generation in low voltage through the consumer (Normative Resolution No. 482 / ANEEL). The purpose of this work is to map the energy potential in Southern Brazil, exploring distributed generation technologies such as wind, solar, biomass and hydro. Then, one should analyze the influence of the inclusion of distributed generation in the planning studies of electrical power distribution systems, both in medium and low voltage.

The reliable and safe operation of electric power systems is challenged to keep them operating obeying operational safety margins, all this within the context of the inherent power generation and consumption uncertainties. Maintaining the continuity and quality of electricity supply implies the need for models that can represent the dynamics of the electric power systems in order to provide tools for the study of dynamics, both in situations of contingencies and demand changes, as in normal operation. This work seeks to determine whether the behavior of sets of coherent bars can provide information on the stability of the electric power system. The proposed approach seeks independence of the use of established models for power electrical systems, through artificial intelligence algorithms applied in the evaluation of the voltage profiles of the various system buses under study.

As decentralized generation capacities in German distribution grids are rising, a growing number of distribution system operators (DSOs) are facing new problems and challenges. On the other hand different technologies and methodologies are emerging and enabling DSOs to handle the new challenges. These technologies are often summarized using the abstract term “smart grid”. The design, installation and in field test of such a smart grid is the target of the project “Smart Area Aachen”. In order to do so the project consortium consists of partners from science as well as partners from industry and is divided into different sub-projects which focus on individual aspects of future smart grids, e.g. communication infrastructure, remote controlled substations and network planning considering new equipment and infrastructure. The following paper presents the sub-project “State Estimation in Distribution Grids” which focusses on distribution system state estimation and optimal meter placement.
