Svar:
Ancillary services to Swedish power networks are different types of services offered to help balance and maintain the stability of the electricity network. These services are essential to ensure the reliable and efficient operation of the electricity system. Here are some common examples of support services to the Swedish power grid:
Frequency regulation: Frequency regulation services are used to balance electricity demand and generation in real time and maintain a stable frequency in the electricity network. By quickly adjusting electricity production or consumption, frequency deviations can be managed.
Backup power: Backup power services provide rapidly available capacity to deal with unforeseen interruptions in electricity production or consumption. This can be in the form of backup power plants or other devices that can be activated when needed to balance the electricity system.
Power balancing: Power balancing services are used to match instantaneous electricity generation and electricity consumption in real time. By adjusting electricity production or consumption, these services can help maintain a balance between supply and demand.
Voltage regulation: Voltage regulation services are used to maintain a stable voltage in the electricity network. By adjusting the voltage, variations in the electricity supply can be managed and ensure that connected appliances and equipment work properly.
Black start services: Black start services are designed to restart the electricity system after a major power outage. These services provide rapidly available power to start up power plants and restore electricity supply in the event of a total outage.
These support services are provided by different actors, including power producers, network operators and specialized service providers. These operators often participate in a regulated market where they offer their services and are compensated for maintaining the reliable operation of the electricity system.
It is worth noting that specific support services and their organization may vary over time and according to the specific regulation and market conditions in Sweden.
