Power System Operation and Control

System operators face significant evolving conditions in power systems with the increasing penetration of RES, the growing competitiveness of the free electricity market, the integration of new technologies and the need to increase flexibility and control capabilities into the operational framework. Operational processes in today’s power system are still primarily based on the availability of sufficient conventional synchronous generation. Operation of the future power system, however, will be characterised by time instances with few to no conventional synchronous generation in operation, urging operators to adapt their knowledge and skills, methods, tools and processes accordingly. This chapter describes the current practices and provides insight into the expected operational challenges inherent to the future power system. To cope with these challenges, ongoing developments of innovative technological- and market-based solutions are presented. Finally, the need for more integration and coordination, and the role of sector coupling in the future power system are highlighted.
