EUROSUNMED Workshop: Grid Code for Renewable Energies - Integration in the Electric Grid



EUROSUNMED organized, together with Ecole Mohammadia d'Ingénieurs and Al Akhawayn University, a workshop on ‘Grid Code for Renewable Energies - Integration in the Electric Grid’ on 2 June 2015 in Rabat (Morocco). The goal of the workshop was to bring together innovative academics and industrial experts in the field of Renewable Energy. See full programme here:





Due to the large and expensive infrastructure of the electric grid, it is pertinent to have a long-time view on its developments and to start early preparing for future changes.  All over the world, energy systems are subject to rapidly changing circumstances; the transition to large-scale integration of renewable energy and less reliance on fossil fuels will cause power systems in a couple of decades to operate in conditions vastly changed from the situation today.


Grid codes are the technical requirements put down by the authorities for all its partakers, such as, the users and power generating stations for connecting to the network and operate as per the standards. These grid codes were first developed based on the characteristics and capabilities of large synchronous generators. They implement the guidelines for even operation of the electric grid and its connected constituents. The process for drafting and approval of grid codes varies from one jurisdiction to another, but typically a grid code is drafted by the transmission system operator through a consultative process and approved by the regulator.


Grid codes for generation units in many MPC countries are determined on a case-by case basis. There is a need for standardized grid codes in order to simplify the grid connection planning process. The main aim of this workshop is to suggest a strategy for further development of grid codes in the Mediterranean Partner Countries, building on experiences from Europe.

The workshop gathered over 60 participants from Moroccan governmental agencies, press and academic institutions; in addition to international research institutes and industry.  The workshop provided a good opportunity for specialists in renewable energies and electric grid to share knowledge and views on grid codes and other issues related to grid integration of renewable energy.


The workshop made clear that the development of grid codes in Morocco is in its infancy.  In addition to the much to learn from European codes, regarding both scope, structure and technical contents.  The presentations made it clear that the ENTSO-E Network Code is a good reference in this regard.  Regarding the detailed requirements, however, one needs to keep in mind that many are specific to each grid and it is therefore necessary to analyze and understand in detail the needs for the Moroccan power system.


Among the points raised during the workshop is the increasingly important development of grid codes for renewable energy as their share in the power system rises. The change from conventional fuel-based generation by synchronous machines to variable wind and solar power connected to the grid via power electronic components has wide implications for power balancing and system stability.  It is important to plan ahead as generators have a long lifetime and simply solving problems as they arise may prove very expensive and disturbing to the entire power system.


This workshop provided a forum for discussion on grid code related issues and for the learning process necessary to develop codes and markets in a fashion suitable for large scale renewable energy integration. The intention is to continue the dialogue amongst the relevant stakeholders and responsible parties in Morocco.
