Electricity Supply Systems of the Future

This book offers a vision of the future of electricity supply systems and CIGRE's views on the know-how that will be needed to manage the transition toward them.

A variety of factors are driving a transition of electricity supply systems to new supply models, in particular the increasing use of renewable sources, environmental factors and developments in ICT technologies. These factors suggest that there are two possible models for power network development, and that those models are not necessarily exclusive:

1. An increasing importance of large networks for bulk transmission capable of interconnecting load regions and large centralized renewable generation resources, including offshore and of providing more interconnections between the various countries and energy markets.

2. An emergence of clusters of small, largely self-contained distribution networks, which include decentralized local generation, energy storage and active customer participation, intelligently managed so that they operate as active networks providing local active and reactive support.

The electricity supply systems of the future will likely include a combination of the above two models, since additional bulk connections and active distribution networks are needed in order to reach ambitious environmental, economic and security-reliability targets. This concise yet comprehensive reference resource on technological developments for future electrical systems has been written and reviewed by experts and the Chairs of the sixteen Study Committees that form the Technical Council of CIGRE.

CIGRE's strategic focus

CIGRE operates the world's foremost power system knowledge development programme of work. At its foundation is CIGRE's unique structure and the wide spectrum of domains covered.

CIGRE's global community influences the strategic and technical direction of the knowledge programme based on real world experiences. This is achieved through a range of bodies within the organisation, and then interpreted by the experts of the Technical Council.

Using this approach CIGRE's work remains relevant to the key factors influencing the world's power systems today and in the future.
