Ensuring power quality in a phase of energy transition
Increasing power feed-in from renewable resources poses new challenges for municipalities and distribution system operators
The stable supply of electric power is any grid operator’s top priority. To avoid fluctuations in power quality and prevent disturbances, grid monitoring, control, and automation systems need to be adapted and optimized across all voltage levels.
Maintaining control of distributed power producers
Ensuring grid stability is becoming increasingly complex
The vast number of small distributed power producers calls for new strategies to ensure consistent power quality. Identifying, locating, and eliminating disturbances and faults as well as the flexible, quick balancing of power production and load consumption require integrated hardware and software solutions that work smoothly together.
Intelligent technologies for stable grids
Automation solutions and remote control technology enhance the reliability of distribution grids
Despite every effort, grid disturbances and faults can never be entirely eliminated. This is why control room personnel must be enabled to work quickly and effectively to resolve problems in a targeted manner. Comprehensive automation and remote-control solutions optimize these capabilities.
More data, increased transparency
Modern electrical grid components deliver, process, and analyze data
One consequence of digitalizing power grids is the steadily growing volume of captured data. These vast quantities of data harbor valuable information that describes the state of the grid, enables advanced computational analysis of changes, and can improve the performance and extend the service life of assets. The hardware and software from Siemens needed for this fulfills all the requirements.
Efficient grid expansion
A combination of robust technology and digital innovations leads to increased efficiency
Maintaining or even increasing grid performance is becoming ever more challenging. With growing efforts, expenses grow as well. Innovative technologies and smart data usage can help municipalities and DSOs to master these challenges and to increase their competitiveness.
Keeping your grids up and running
Using sophisticated tools and solutions for fast grid restoration
Unplanned outages cannot always be avoided. Flexible solutions for local and remote monitoring enable the fast and efficient restoration of cable grids and overhead lines.
Optimizing business operations
Comprehensive and efficient ways for municipalities and DSOs to get the most out of their OPEX
The growing demand for power from industries and households can be fulfilled simply. With modern technologies and innovative solutions such as optimized voltage and capacity management, self-healing grids, and by avoiding losses of any kind.
SICAM Microgrid Controller
Maximum security in operating microgrids
Microgrids are a reliable alternative when autonomous power supply is needed, such as on islands, or when optimizations are required for higher level grids or supply costs. With grid-connected operation, microgrids enable energy to be reliably provided from renewable sources, at both high-peak and low-peak times. They can also influence reactive power and help save money by regulating the maximum power demand or infeed. Microgrids offer high reliability and improved energy quality. And they have a further advantage: Microgrids can operate independently of the higher-level grid.

The SICAM A8000 series supports a smart 3-stage approach for grid optimization:
- Monitoring: The first stage focuses on the monitoring of stations to enable rapid fault localization and high availability.
- Telecontrol: The second stage involves switchgear telecontrol in addition to monitoring, thus minimizing downtime. Thanks to this application, fault isolation and power supply restoration of de-energized network sections are no longer difficult tasks for power supply utilities.
- Load flow control: In the third stage, the effects of decentralized power feed-ins are managed via automation. Network losses can be significantly reduced this way.
