Siemens in Amsterdam to present intelligent solutions for smart buildings

Title: Siemens in Amsterdam to present intelligent solutions for smart buildings

From October 9 to 11, 2012, Siemens Infrastructure & Cities will be presenting a consistent, end-to-end concept for the intelligent distribution and use of energy in Amsterdam at three specialized events that have been rolled into one: “Metering, Billing/CRM Europe,” “Transmission & Distribution Europe/Smart Grids Europe,” and “Smart Homes” (Hall 2, Booth M04). The concept includes smart metering and smart grid solutions for meter data management and energy management in buildings, a smart grid consulting tool, as well energy storage solutions to stabilize distribution grids

Energy consumption will increase around the world in coming years – by at least 60 percent to about 37,000 terawatt hours (TWh) in 2030. Cities already account for over two-thirds of global power demand. The share of renewable energy sources must be increased if those energy needs are to be met in a way that is compatible with the Earth’s environment and climate. Yet today’s energy supply grids were not designed for rising power consumption or for an increasing share of renewable power generation, which can fluctuate sharply. That’s why the introduction of smart grids and the interaction of grids with smart buildings that generate, store, and consume energy will represent the greatest challenges for the energy industry and for building operators over the next two decades.

Siemens uses its Smart Grid Compass, a consulting and analysis tool, to help energy providers, cities, and building operators implement a smart power supply grid. Following an analysis of existing processes and the technology that is available in the grid, Siemens experts work with energy providers to develop the right business strategy for a smart grid. The objective is to find the best solution for a smart grid and get it up and running professionally while minimizing risks and keeping budgets reasonable.

Meter data management (MDM) systems support energy providers that use smart metering by processing large quantities of data. The EnergyIP meter data management system has been part of the Siemens smart grid portfolio since Siemens acquired eMeter in January 2012. EnergyIP connects existing IT systems into a smart metering infrastructure through a SAP-certified interface. This allows energy supply companies to use smart metering throughout their systems – from the meter to billing and from system management to grid planning.

The DEMS distributed energy management system networks and combines individual decentralized power generation sources so they can be centrally controlled as a single virtual power plant. The system processes information such as weather forecasts, electricity prices, and energy requirements. A deployment plan for all of the connected plants is prepared and monitored based on that information. Predictions of the amount of electricity that will be generated from renewable energy sources are based on weather forecasts and characteristics of the plants, so the deployment plan minimizes the power generation and operating costs of plants that have been combined into a virtual power plant.

Siemens supplies building automation and security technology for smart buildings, offering an additional opportunity for decentralized energy management. The use of smart meters to exchange data allows energy providers to use the equipment, such as thermo active construction material or thermal storage, located in the buildings that are connected to their systems as decentralized energy buffers. This means smart buildings can serve as energy storage units for electrical power generated from renewable energy sources, reducing peak loads and conserving primary energy. A smart grid can also work with a smart building to help reduce energy costs thanks to special consumption rates (smart metering). In order to achieve this, smart buildings can react to price signals and deduce actions like the reduction of consumption in times of high tariffs and automatically shifting the consumption to times with lower rates. To be able to do this, building operators must control all heating, ventilation, and air conditioning applications, as well as lighting and shading; in a way that is energy efficient. In addition they have to coordinate the decentralized power generation units and operate the thermal and electrical storages proactively.

The Siestorage energy storage unit is one of Siemens’ offerings for stabilizing distribution grids that must handle a high percentage of decentralized renewable power generation plants. Siestorage is based on lithium ion batteries. Using a compact battery and converter cabinet as the smallest unit, the energy storage system can be expanded to a capacity of two megawatt hours (MWh) and output of eight megawatts (MW). The energy storage system can also be used as a backup power supply for production facilities, data centers, and hospitals. The energy storage units are also available for energy-efficient buildings, island networks, smaller auxiliary power systems, public transport and electromobility applications.

Intelligent transformer substations by Siemens improve the stability of medium- and low-voltage grids, which are increasingly being supplied from decentralized renewable energy sources. The substations include compact medium-voltage switchgear with communication capability, regulated distribution transformers, and remote control and automation components. Siemens primarily uses medium-voltage 8DJH and 8DJH 36 gas-insulated switchgear, which can be integrated into a smart grid using smart short-circuit and directional earth-fault indicators and modern sensor technology.
