„Electrical Power is the backbone of our society“

Electrical energy is the backbone of our society


Future grids require more flexibility

Increased energy trading

Increasing distance between generation and load

Fluctuating infeed

Increasing short-circuit currents

High supply quality along with greater network complexity and vulnerability

Drivers for flexible and (cost)-efficient grids

Integration of distributed energy resources

Cost pressure

Aging infrastructure and lack of experts

Legal & regulatory framework


Some Statements on “Smart Grids”

The complexity of the already complex electrical system will

increase.

We need to adapt our grid to get all opportunities in

place born by new technologies.

A SmartGrid Applied system integrate the data, equipment and associated process by the investment in Advanced Meteringnfrastructure , broadband over Power Line , and Distribution automation

Pathways to a Smart Grid

From To

Manual reaction to critical network situations

Blackout prevention by increasing the situational awareness and automated counter measures

Primary equipment condition not well known

Condition monitoring for controlled overload ofbottlenecks and reliability centered asset managem.

Complex Engineering, Testing and Manufacturing

Plug-and-play by Smart Substation Automation

Central generation, decentralized consumption

Integration of distributed generation and storageby virtual power plants

Unmanaged, not transparent consumption

Flexibility: fulfilling customers’ needs whilst responding to the changes and challenges ahead

Accessibility: granting connection access to all network users, particularly for renewable power sources and high efficiency local generation with zero or low carbon emissions;

Reliability: assuring and improving security and quality of supply, consistent with the demands of the digital age with resilience to hazards and uncertainties;

Profibility: providing best value through innovation, efficient energy management and ‘level playing field’ competition and regulation.

The Siemens approach is to focus on each customers needs to evolve (migration) its grid to smart grid

The Siemens Smart Grid Visionis driven by the requirements of our customers


Condition Monitoring increases your Profitability

Multifunctional meters for all tariff models:Integrated breaker relay Interface for meters of other media Prepared for home automation and other servicesLoad switching deviceAs replacement for ripple-control devicesGateway for third-party meters


AMIS Reference Project for

The most important reasons for implementing an AMIS system for Energie AG are:

� Automation of metering processes (meter reading, blocking of customer installations, billing, prepayment services, etc.)

� Significant improvement of customer processes

� Implementation of various tariffs

� Quality improvement of consumption data due to monthly meter reading

� Replacement of ripple control

� Recording of the customer supply

� Automation of the transformer stations
