Grid codes – stricter rules for stable grids with decentralized power generation
Grid codes have been standard for a number of years in many countries and are mandatory for the connection to the grid. They define the technical standards and requirements for transmission system operators (TSO), the distribution system operators (DSO) and the connected power generation systems in order to ensure the stability and proper interconnection of the different systems. Driven be the growing influence of renewables and decentralized power to the grid the requirements for power generation systems are getting more challenging and result in stricter rules for all
power generation systems. There are currently many different national and local standards in place, often categorized according to voltage level (low / medium / high) and connected power.
The grid code requirements can be condensed into two different categories:
• Static grid code requirements (Steady-state voltage control) • Dynamic grid support (dynamic network requirements)
