Planning and optimisation of active distribution systems: An overview of CIGRE Working Group C6.19 activities

This paper presents an overview of the activities of CIGRE C6.19 Working Group (WG), focusing on the planning and optimization of active distribution systems. This builds on the recommendations of CIGRE WG C6.11 that focused on the development and operation of active distribution networks (ADNs). The C6.19 WG aims at addressing the following issues: (i) Survey on the state of the art on planning for active distribution systems; (ii) Requirements of planning methodologies; (iii) Identification of short, medium and long term models for active distribution system planning; (iv) reliability models of active distribution systems; and (v) algorithms for active distribution system expansion and upgrade planning, including demand-side integration and storage
