Grid codes play a critical role in building trust between the system operators and stakeholders. They remain one of the central tools to ensure the security of supply of a power system at any time. Grid connection codes define technical requirements, regulations, and behaviour for all active participants in the power system, including power generators, adjustable loads, storage, and other units. Grid codes are evolving, to enable innovative technologies to be connected to the network safely, without compromising the reliability of supply.

This report contains the latest developments and good practices to develop grid connection codes for power systems with high shares of variable renewable energy – solar photovoltaic and wind. This report elaborates on the latest developments and experiences related to technical requirements for connecting variable renewable energy generators and enabling technologies such as storage, electric vehicles or flexible demand.
