Grid codes module. This module is responsible of the definition of the grid connection codes and the management of the provided services to the grid. In simple words it defines the requirements and restriction for the electricity energy exchange with the main grid. This is critical in weak grids or energy islands (as the ones studied in MUSE GRIDS project) but also have a great impact in any other situations. The operation modes will be communicated to the high-level control module as restrictions, generation availability or energy demand in order to accomplish with the grid codes. This will be basically a configuration module to select the different connection modes. This module has its counterpart at local level where the low-level control must guarantee that the defined grid codes are fulfil in real-time. Several local active and reactive control modes have been developed in the MUSE GRIDS project. These control modes have been designed by analysing DSO requirements in different countries. Each mode of operation can be activated in a predefined way by the controller through internal parameters or can be activated / deactivated by the operator through the SCADA.
