Briefing about of the Conference Within the intersection of technology innovation, carbon reduction policies, and rising fuel prices, there are a number of utilities and energy distribution companies around the world focusing on investing in "smart grid" infrastructure and becoming a utility of the future. The intent of this presentation is to first offer a perspective on what characterizes the smart grid and how one can recognize it when this stage is reached. The discussion will explore selected technology and systems innovations needed to achieve this vision, as well as explore the policy issues that will be required to facilitate its deployment. Of prime concern is the availability of the level of investment required to transform the power grid into the vision that is sought by a number of leading utilities. On the consumer side, we need to ensure that benefits are being sufficiently allocated as key participants in the smart grid and that utilities are considering the increased number of opportunities to fundamentally change the consumer experience in purchasing, managing, and consuming energy. Finally, in order to drive smart grid efforts, we need to directly address the various barriers to ensure that this infrastructure truly contributes to greater levels of national security, benevolent climate change, and economic growth - overall, a "smarter" planet.

Briefing about of the Conference
Pre-Conference
The European power grid is undergoing profound changes in the way it is planed and operated. Theses c

hanges are triggered by numerous factors among them:

• Development of the internal EU electricity market (market deregulation and open access, intensification of cross boarder trades, …)

• Environmental policies and security of supply (reduction of C02, development of renewable and alternative energies, management of energy efficiency, etc.)

• Increasing Europe competitiveness

• Integration of new member states

Hence, Europe has developed a vision for its strategic development: Sustainability, competition, security of supply and innovation.

As far as power grid is concerned, it is expected to be

• flexible: able to fulfill customer needs

• accessible: to all network users particularly to RES and high efficiency DG with low or zero CO2 emissions

• reliable: assuring and improving quality of supply and resilient to all kind of aggressions

• economic: best value for all participant on the basis of innovation, energy efficiency and regulation

EU targets give clear signal in the direction of this vision. It consists in setting strategic objectives that can be quantified (3x20%), ie:

• 20% CO2 emission reduction by 2020 (compared to 1990)

• 20% increase in energy efficiency by 2020

• 20% more renewable energies by 2020

In order to reach these strategic objectives, specific instruments for planning have been established and shared at the European level. Some of those instruments are:

• European Commission (EC) directives and incentives (Harmonising regulatory and commercial frameworks in Europe, facilitating cross border trading)

• Participation to the development of interconnections

• SmartGrid Platform and strategic research agenda (FP7)

Conference:
Distribution grids in different parts of the world are undergoing tremendous changes in the ways it is planned, operated and controlled. These changes are mostly driven by several factors such as open access, environment issues and Distributed Energy Resources (DER). In addition, the development of Information and Communication Technologies represents an opportunity of distribution grids to face the above mentioned changes in an innovative, flexible and economic way.  Indeed, future distribution grids will carry out more intelligence and become active interacting with the end user as well as all its actors while fulfilling environmental requirements.  

The presentation will deal with these distribution grid challenges and trends. It will start with a review of the structure of electric power and the new paradigm it faces which results.

The historical organization of power systems as integrated monopolistic companies will be recalled including the review of the structure of the electric power system from generation to customer service encompassing transmission and distribution grids

Briefing about of the Conference
Pre-conference
The Planning of the National Electric System in Mexico. A General View 

We present the methodology, criteria and models that are used in the expansion planning of the National Electric System of Mexico. At a difference from other national electric systems in Latin America, Mexico still develops a centralized planning of all the segments of the electrical industry; however, the generation plan is open to competence; the transmission and distribution services are a responsibility of the federal utilities in their full cycles. It is discussed the impact in the planning process due to the changes in the regulatory frame work, uncertainties in the planning process components and technological evolution. Finally, the tendencies regarding the application of new technologies in the planning process in Mexico are also discussed.

Conference
El sistema de transmisión consta de tres elementos:

1.Hardware que lleva corriente (líneas, transformadores, etc.),
2.Sistemas de control y comunicación (interruptores, computadores, etc.), y
3.Normas y procedimientos.

La causa inicial de cada apagón grande ha sido un fracaso de elemento 2 o 3. Estos elementos forman redes superpuestas encima de las redes de elemento 1. Hay que analizar las redes superpuestas y sus interacciones para determinar la exposición a apagones y como disminuirla.

Briefing about of the Conference
Conference
The major increases in oil prices and the rising environmental concerns are key drivers in the growing popularity of electric and plug-in hybrid vehicles. Car manufacturers understand this trend quite well and are developing new models. For the 90% of Americans who use their cars to get to work every day, the average daily commute distance is 45 km and the average daily time that cars remain parked is 22 hours. A salient feature that these vehicles have in common is the batteries, which provide good storage capacity that can be effectively integrated into the grid.  

We focus on the design of a conceptual framework needs to integrate the electric vehicles into the grid – the so-called V2G concept. The basic premise we use is to treat the battery vehicles as distributed energy resources that can act both as supply and demand resources. We assess the deployment of an aggregation of battery vehicles for the provision of frequency regulation – requiring very fast response times – and energy supply for peak shaving. We also investigate the impacts of the aggregated battery vehicle-charging load on the low load generation schedules and on regulation requirements. The assessment of these impacts takes into consideration the explicit representation of uncertainty and the importance of the state of charge as a key variable in the use of the batteries for the supply and demand roles. For the framework completeness, we also explore the role of the energy services provider in the V2G integration. The role of V2G in the context of renewable resource integration is discussed. In addition, we present the need for the communications/metering system to enable the integrated battery vehicles to effectively participate in the operation of the grid and electricity markets.

Tutorial
Congestion Management
Congestion in the transmission network has become a critical problem for electricity markets in the competitive power industry. Its wide range of impacts, ranging from the way the system is operated to the behavior of each market player in the congestion-modified market, may prevent the use of the lowest-priced resources to meet the demand and may, in addition, facilitate the attempt of a particular seller to exercise local market power. Many observers of the industry see congestion as a key barrier for the establishment of vibrant competitive markets. This presentation focuses on the impacts of congestion on the individual market players. The evaluation of key metrics for congestion management, including the congestion rents, requires the efficient allocation of transmission services and the calculation of appropriate locational marginal prices (LMPs). This requirement is particularly acute when there are bilateral transactions coexisting with the centralized pool markets. We propose a new formulation for this purpose, which captures more appropriately the contribution of the bilateral transactions to the social welfare than the conventional one. The solution of the proposed formulation not only leads to the efficient allocation of transmission services to both the pool players and the bilateral transactions, but also results in more realistic LMP signals than the evaluations done with the conventional tool. We assess analytically the capabilities of the proposed formulation and solution and quantify the improvements in the evaluations over those done using the conventional approach. Throughout the talk, we provide a good intuitive explanation of the impacts of congestion by explaining this phenomenon on a simple system. We also show the role of price-responsive demand in the mitigation of the possible exercise of market power. We illustrate with simulations the congestion impacts using different test systems of various sizes including the IEEE 118-bus network.

Transmission Investment In The Competitive Environment
An important conclusion of the mega-blackout of August 14, 2003 is the fact that the transmission network is the weakest link of the restructured electricity business in the United States. A key aspect of electricity restructuring is the unbundling of the industry leading to the creation of new structures such as the Independent Grid Operator (IGO), the entry of many new players such as brokers, marketers and independent power producers, and the separation of the ownership from the control and operation of the grid. The decentralized decision making in the new structure, the large number of new players, the proliferation in the number of transactions on the networks and the markedly different utilization of the transmission system than in the way it was planned and designed have all contributed to the severe stressing of the transmission grid. This has resulted in frequent congestion situations with customers competing for the scarce and heavily constrained transmission services. Moreover, despite the more intense utilization of the grid by the many established and new players, investments in the transmission network have failed to keep pace with the increasing demand for transmission services. The need for investment to improve and expand the grid and to reliably maintain the existing network has been met poorly under competitive markets. The sluggishness of transmission investment is caused by numerous factors, but a principal one is the substantial mismatches between those benefiting from the new facilities and those paying for them are often such as to prevent the investments from being made. There is an acute need to set up effective procedures to ensure the timely recovery of transmission investments. In other words, investors need appropriate market incentives to expand and improve the grid.

Under the new paradigm, the economic signals resulting from the daily markets, such as locational marginal prices and congestion and other metrics, need to be explicitly considered together with the economics of investment in new assets. This talk outlines the key challenges and complications in the transmission investment arena in the competitive environment. We present a framework for the analysis of issues in the planning and investment of transmission in the competitive environment. We construct the framework by extending the framework developed for congestion analysis through the addition of a new layer for transmission expansion/investment issues. This extension requires the development of appropriate metrics to allow the evaluation of the necessary measures over the planning horizon. A key attribute is the ability of the framework to effectively reflect the interactions of the investments with the network. We apply the framework to investigate transmission expansion scenarios in several systems from the IGO point of view and present representative results.

Briefing about of the Conference
The general acceptance by the electric industry of Intelligent (read “Integrated”) Electronic Devices has created a bridge between fields that were normally separate. In fact measurement, control and protection divisions at manufacturers, utilities, consultants, maintenance and other vendor and service providers are fading away based on the multifunctional devices thar we see more and more in new and refurbished plants and substations.  In addition the introduction of new variables based on Syncronized Phasor Measurements are integrating a complete new and exceptionally promising set of measurements that provides a new “dimension” complementing the normal analog values that have been used for all purposes since the beginning of the electricity production and supply. This paper analizes the integration trends derived from the mentioned technologies, their impact and the benefits of such changes that are taking more and more momentum and will certainly be part of the global solutions that are needed to avoid blackouts while increasing power system reliabilty
