The Siemens Spectrum Power Energy Management System (EMS) balances generating units with consumption in consideration of the capacity of the transmission network. Intelligent Alarm Processors (IAP) reduce the critical time needed for analyzing faults in the grid and finding the correct alleviating response. Innovative Voltage Stability Analysis (VSA) applications, running automatically and independently, alert the operator right in advance before critical situations can occur. Increasing grid reliability is completed by Optimal Power Flow (OPF) applications, continuously striving to keep the system voltage at a high level and eliminate any invalid voltage conditions -control measures determined can be automatically put in place in a closed-loop-control fashion.

Please use the following explanation and or further Information contact: Overall: An integral solution is required to manage the aging infrastructure. Also, we have to bring the technical and financial world of assets together. The question behind is: How can I go to a preventive and Return of capital optimized maintenance model? "Grid Asset management" – GAMS satisfies that demand. It starts at the planning of the grid and reaches to its development and extension. Also it reaches up to the maintenance or the partial or complete renewal of the technical equipment. We have to balance in an intelligent way between technical feasibility of upgrades and capital efficiency of the distribution network. Also, the Utilities market is characterized by less financial resources for improvements and implementation of automatic running processes to maximize the return of invest. Definition: Condition Monitoring is any kind of system or service giving an information on the ageing or health condition of a primary device in operation, derived from special sensor and/or from data typically available. In Scope: Monitoring of primary assets including BoP (balance of plant) inspections Special sensor data Data typically available from control&protection devices (I, U, t) Out of Scope: Protection functions (CM not for tripping) Monitoring of grid load flow condition e.g. for blackout prevention Who are the potential customers? grid operators and grid owners Customer needs in focus Extended lifetime Asset protection Reduced maintenance costs Transmission capacity increase Congestion (Engpass) Management Increased reliability Outage avoidance (in correlation with blackout prevention) Verification of risk management (responsible custodianship) Early warning for damages caused by abnormal weather conditions e.g. OHL icing Further contact: ISCM: M.

Notas de la presentación
Please use the following explanation and or further Information contact: In the recent past, the discussions about energy technology and energy economics have gathered momentum. There are several reasons for that: Due to the rapid economical progress in countries like China or India, the world wide energy consumption growths in parallel. For example, China installed more than 100 GW electrical generation capacities in 2006. In the last time, the prices on the energy markets have increased. For example, in the Europe Union, the electricity prices for households and industry rose in total by 9% and 31 % respectively between January 2000 and January 2006 (figures for the EU15 countries). At least with the IPPC reports (Intergovernmental Panel on Climate Change) published in the beginning of 2007, there is a common understanding that the global warming is caused by mankind. One major factor is the emission of carbon dioxide, which is mainly produced by generating electricity with fossil energy. The consequences of the global warming are so serious, that a world-wide reduction of the carbon dioxide emission is urgently needed. Triggered by the liberalisation of the energy markets in some regions of the world, the operation of the electrical grids have changed. For example, the grids within the UCTE (Union for the Coordination of Transmission of Electricity) were designed for a regional power adequacy. But do to the increasing trades with electricity, extensive cross-border energy transits have become daily business in transmission system operation. �In a Smart Grid, the grid operator has active customers who are the consumers as well as the producers using decentralized generators. Therefore, the decentralized generation of electrical power, heat and cold energy becomes more and more important. The generation of these types of energy nearby the consumers offers economical and ecological benefits. It is assumed that the portion of decentralized generation will increase in the future. The Wuppertal Institute for Climate, Environment and Energy states in a study that the portion in Germany will increase significantly and will reach 45% in the generation mix for electrical energy until 2050. Worldwide, similar trends can be recognized. For example, China plans to increase the portion of the renewable energy up to 10 % until 2010. To reach this target, China has developed a national strategy for renewable energies and will invest more than 50 Billion US Dollars together with other investors. The ecological and economical impact of decentralized generation can be sustainable improved by setting up so-called Virtual Power Plants. A Virtual Power Plant is a collection of small and very small decentralized generation units and flexible loads, which are connected by a communication network and monitored and controlled by a superordinated energy management system. In particular, the following generation techniques are of a special interest for Virtual Power Plants: Biomass power plants Photovoltaic Fuel cells Cogeneration of heating or cooling energy and electrical power in block-type power plants or micro-turbines Wind power plants Small hydro power plants Biomass can be used for energy generation in different ways. Traditionally, wood is used for firing. Due to the high prices for oil and gas, wood has a renaissance for firing in stoves with pellets. More interesting for Virtual Power Plants are chemical processes, which produce synthetic fuels from biomass, e.g. methyl and ethyl alcohol, biogas or synthesis gas. These fuels can be stored and used in gas engines or micro turbines, methyl alcohol can be used in fuel cells. In the past, the power output of decentralized generation like block-type power plants was in the range of some hundreds kW to one MW electrical output and some hundred kW thermal. In the meantime, we see a trend towards small block-type power plants which are designed for supplying smaller buildings. They use gas engines, stirling engines or micro turbines. Currently, field tests are performed with small fuel cells for supplying one-family houses. These types of micro block-type units are mainly designed for generating heating or cooling energy. The generation of electrical energy is a welcome secondary effect. The thermal output of the units is between 10 and 20 kW and the electrical output is up to 5 kW. All of these generating units have one big advantage: The total efficiency factor can exceed 80 % if heating and cooling energy is produced simultaneously with electrical power. This helps to reduce the cost for energy supply and to reach environmental targets, e.g. the reduction of carbon dioxide. By setting up virtual power plants, this advantage can be used to increase the overall energy efficiency of a power system. Up to now, not many Virtual Power Plants are installed. The existing installations are mainly based on large power units. This means that there are only some units, which are connected with conventional remote terminal units (RTU) to the energy management systems. With the increasing installations of smaller units, the structure of Virtual Power Plants will change: the number of units will increase and the communication has to become simpler and much cheaper. By using small CHP (Combined Heat and Power) units, Virtual Power Plants will encompass several hundreds of these generation units.

The intelligence off the grid is mainly in the Control System and all changes in the network infrastructure have to be manually add. Distribution networks information normally only manually updated, therefore no online-data are available only status information. At lower voltage levels the possibilities for communication are very limited. At least the strategic Ring Main Units and Poletops should be implemented within the communication structure.

Distribution network operators seeking to ensure economical success and expand further under these framework conditions must optimize existing network operation processes and develop new fields of business. The Smart Metering solution by Siemens provides the ideal conditions for doing so. It combines metering and management of distribution networks in one system and was developed explicitly for the special requirements of the liberalized energy market. As a complete solution, the system acquires data and information of households, special contract customers and the distribution network infrastructure and transmits them to a control center. This allows network distribution operators to optimize essential key processes and offer new services and data to their customers, both on the supplier as well as the consumer side. The Smart Metering solution by Siemens is the basis for Smart Grid solutions.

The main reason for installing a building management system (BMS) is to ensure maximum comfort for the occupants (or a perfect process conditions) while minimizing the operational costs (energy consumption, equipment maintenance and replacement, alarm handling etc.). �BMS control all major energy relevant devices within buildings:� Heating, ventilation and air-conditioning equipment (HVAC) Integrated room automation (window opener, blinds, lighting etc.) Water and power systems Distributed electricity Generation (photo voltaic, combined heat �and power plants (CHP), wind etc.) In future, our BMS may also take control of energy storage devices �(e.g. electric cars) In addition to that, our BMS solutions always come along with sound sub-metering solutions, which not only support intelligent automation, but also enable building operators to make informed decisions and continuously optimize their building’s performance. In combination with smart metering solutions and/or direct communication with a smart grid management station, a BMS may actively participate in the grid by controlling a building’s energy profile.
