SC 4

Technical Committee 4 has adjust the scope of work following the goals from the climate-energy strategies that encourage implementation of low carbon technologies to increase share of renewable energy and energy efficiency. The new challenges deals with the network integration of distributed energy resources (DER) including distributed generation (DG), energy storage, responsive loads and electric heating (heat pumps) and electrification of road transportation. Also of interest are the opportunities for more efficient management and utilisation of electricity and the evolution towards more efficient, lower carbon end use. Energy management systems for DER at the level of smarthome, smartcity or smartgrid level and new business models for DERs, as well as real experiences of integrating DG/DER within distribution networks will be welcome as will examples of technical, commercial and regulatory solutions for DG/DER. Developments in DG/DER technologies and techniques for assessing their contribution to distribution networks and techniques for improving the efficiency of electricity delivery and end use are also important.
