b'cired2021.orgSESSION 4:DISTRIBUTED ENERGY RESOURCES AND EFFICIENT UTILISATION OF ELECTRICITYSession 4 deals with the challenges of adapting distribution networks to facilitate the efficient integration of low carbon, renewable and Distributed Energy Resources (DER), from the integration perspective. These include Distributed Generation (DG), energy storage, new loads (e.g. electric heating and Electric Vehicles (EVs)), active demand and aggregation of DER (e.g. Virtual Power Plants). DER integration challenges are likely to feature across all CIRED sessions so Session 4 specifically focuses on emerging technologies and solutions, results from research, development or demonstration programmes with results from network and system integration trials being particularly valued. Session 4 papers will highlight the integration of DER within distribution networks through technical, commercial and regulatory solutions. Papers may describe developments in network management, demand side response, energy storage integration, efficient utilisation of electricity, network monitoring, telecommunications and data analytics and the role of DER in wider DSO business operations. Also within the scope of Session 4 is whole energy system optimisation (including integration across other infrastructure systems and energy vectors), efficient management of network losses and the results from the larger smart grid demonstration projects.
