Dr. Elizondo works in the transmission team within Quanta Technology and is responsible of managing and conducting studies for interconnections of diverse types of generation into the electric power grid.
Abstract: Application of energy storage technologies in planning, and operations control of electric power systems. The tutorial begins with a review of the background and history of energy storage technologies including a description of the main storage media currently in use. The potential of energy storage applications in the transmission, generation and control centers segments is presented in detail through a description of more than 15 energy storage projects already installed around the world. The tutorial also includes a review of the energy storage market for Latin America, as well as some specific applications that are being evaluated in Mexico, Brazil, Colombia and Chile. The tutorial presents the regulations that have been designed to stimulate energy storage in the United States of America as well as the current state of regulations in Latin America. The most beneficial applications for the electric power system are presented in detail, such as the use of energy storage to more effectively integrate renewable, solar and wind generation, investment deferral, and congestion relief. The tutorial ends with a review of the state-of-the-art software and hardware of battery-powered energy storage systems and the vision of the future.
TUTORIAL T2: “Optimal Dispatch of High-Penetration Renewable Energy Integrated Power System”
Speaker: Ruben Chaer/ Manager of Technical and National Load Dispatch - ADME and the developer team.
Short Bio: Ruben Antonio Chaer currently works at the Administración del Mercado Eléctrico (ADME) of the Uruguay as Techincal Manager and at the Instituto de Ingeniería Eléctrica (IIE) of the University of the República Oriental del Uruguay. Ruben does research in Electrical Engineering. Their current project is 'SimSEE'
Abstract: The Uruguayan system has incorporated 1500 MW of wind energy and 220 MW of solar energy. The installed capacity of solar plus wind power exceeds the daily peak of the system's Load in 70% of the days of the year. The programming of the optimal operation of the National Integrated System, therefore presents a challenge in that it is not known with certainty what resources will be available for the operation in the coming days.
The Electricity Market Administration (ADME) in cooperation with the Electrical Engineering Institute (IIE) has developed a set of tools, in open-source mode, that allow the calculation of optimal operating policies assimilating the forecasts of the different variabilities (hydro , wind, solar, demand).
In this tutorial, an introduction is made to the problem of optimal operation in a system with high variability in its resources and the tools developed for modeling such variabilities for generation and assimilation of forecasts. It shows how these tools are in operation in Uruguay and how, based on them, the information of the probabilistic dispatch of the following 168 hours is generated continuously every hour. This information has undoubtedly an important value for the operation. As an example that is useful to visualize the probability that the different plants are necessary, it allows estimating possible blocks of exportable energy and evaluating the risk associated with committing said blocks to a price. Another possible application would be to use the Spot price projection of the following hours to encourage the development of Responsive-Demands in the future.

TUTORIAL T6: “Transformers for HVDC”
Speaker: Ing. Alvaro Portillo Laurino, Independent Consultant in Transformers
Abstract: The converters transformers are an integral part of HVDC power systems. More a more are used around the world HVDC systems for the energy transmission in long distances, back-to-back stations to frequency conversion, and networks with long submarine cables. In these systems the converter transformers are one of the most expensive and most critical pieces.
The design of converter transformers presents a lot of challenges compared with conventional transformers and converter transformers present a high failure rate in service.
The coexistence of high AC and DC voltages put specific requirements on the dielectric insulation design of this type of transformers.
The short-circuit design is critical in the case of a failure in the thyristors of the converter and the thermal design and hot-spot determination require detailed thermal-hydraulic models.
Also, non-sinusoidal currents give rise to additional losses which are to be considered. The non-sinusoidal currents that flows in the windings present greater demands than the usual ones in the on-load tap-changer that must be considered in their design and selection.
The dielectric connection from the valve windings to the HVDC bushings, that connect the transformer with the converter, are highly complex and are developed and tested one by one for each different design.
From the manufacturing point of view the drying and impregnation of pressboard barriers between windings is of paramount importance to avoid partial discharges.
Finally, the testing also presents a lot of particularities including a lot of tests to probe the DC dielectric withstand of the transformer insulation structure that require very special test equipments.
