Blackouts with Spectrum Power
Constantly monitoring the stability of your grid and providing mitigation measures
The operation of power transmission systems has never been more demanding. Many new stakeholders, new sources of energy, fluctuating demand, and new regulations need to be considered, while the grids need to be able to react to an increasing degree of volatility. The application of more digitally driven solutions helps ensure stable grid operation under these new conditions.
Siemens helps you to ensure an efficient and reliable power supply with a focus on long-distance transmission, the grid integration of renewables, and strengthened grid stability.
With Spectrum Power you can take advantage of
Moreover, in response to the increased use of wind energy, the Spectrum Power Short Term Wind Power Flow STWPF package allows for power generation forecasts and provides valuable input to load flow congestion management.
As a leading supplier of transmission management solutions Siemens has years of experience and thus proven success in networks of every conceivable size and complexity.
With its fast and secure innovation cycles, Spectrum Power is constantly up to date with new standards and market needs.

Power system stability is becoming increasingly important for today’s system operation; stability limits are often reached far earlier than thermal or rated limits. The Voltage Stability Analysis (VSA) application provides an online tool to identify voltage stability problems. VSA can be used in conjunction with static voltage or thermal security analysis to provide a more complete picture of system security by determining how close the system is to voltage collapse. An even more comprehensive stability analysis extending to transient stability and small signal stability is enabled by the integration of SIGUARD® DSA – an automatic and intelligent real-time dynamic security assessment tool for the calculation of the stability margin and the validation of remedial action. This contingency study runs in automatic cycles and is always based on the most recent snapshot from the State Estimator application.
Due to its immanent dynamics the power system under the presence of large-scale renewable power generation cannot be run reliably just based on operator experience. The transmission grid operator rather needs a sophisticated application package directly in the control room for managing these challenges during every day operation:
The Spectrum Power Wind Power Forecast application capitalizes on the experience of Red Electrica de Espana (REE) - a TSO that manages one of the world’s largest shares of wind power generation - and forecasts the yield from wind plants based on meteorological and turbine availability data.
Renewable generation forecasts change as rapidly as the weather changes and so do power flows, grid loadings and potential violations of operational limits in the future. The capability to look forward into the near term operational timeframe for potential problems becomes crucial. The Transmission Analysis Forecast feature of Spectrum Power allows for analysis of the transmission system reliability by executing Power Flow and Contingency Analysis automatically for multiple time intervals in the near-term operation time horizon. Up to 24 intervals can be utilized with interval step sizes of 15 minutes or one hour. Potential transmission system limit violations are reported for each time period.
Renewable generation tends to be located far away from the system load centers leading to unusually high transmission line loadings with the potential consequence of severe threats on system stability. Therefore, extending traditional power system analysis to transient stability simulations is a mandatory step: SIGUARD® DSA (Dynamic Security Assessment) performs time domain simulations for given sets of contingencies in real-time, offers a very simple and catchy visualization of the results, and provides recommendations for operators.
Stable system frequency is essential for reliable power system operation; keeping power interchanges with neighbors at scheduled values contributes to the economy of power supply.
Both tasks remain to be core tasks of the Transmission System Operator (TSO) addressed by Automatic Generation Control (AGC). Power systems tend to become more and more integrated requiring the AGC response to be well coordinated with neighboring TSOs and meet agreed quality criteria.
Available primary, secondary, and tertiary reserve levels must meet specified requirements for ensuring adequate reliability of supply – an increasingly challenging task e.g. due to the increasing amount of renewable generation. Last but not least, all this has to be provided at minimum cost.
Spectrum Power is your constant eye on generation. It features a host of functions to perfectly meet your needs for generation control:
The ever increasing amount of cross-border energy flows increases the need for closer cooperation of TSOs including the need for more frequent exchange of larger amounts of data. In this context, ENTSO-E has developed the Common Grid Model Exchange Specification (CGMES) as an IEC technical specification based on the IEC Common Information Model (CIM) family of standards.

Research and scientific partners in Germany cooperated in the DynaGridCenter research project. The goal was to develop advanced assistant systems for automated grid control and outage prevention.
As main part of the project, a dynamic grid control center, based on Siemens Spectrum Power was installed at the Technical University of Ilmenau. Newly developed dynamic applications are integrated as assistant systems for e.g. “Dynamic Security Assessment”, “Adaptive Protection Settings” and “PMU Data Streaming Analytics.
