    Evolution of Distribution Grids – DNO to DSO Transformation

    Webinar Overview:
    The common practice in traditional DNOs is passive distribution grids with uni-directional power flows, and highly predictable load and voltage profiles that can be managed with pre-specified rules and pre-set regulating devices located on pre-specified locations. Therefore, a very low or no real-time interaction was required from traditional DNOs in order to keep the grid stable.
    A tremendous paradigm-shift in today’s distribution grids is underway as a consequence of a large penetration of distributed energy resources (DERs) coming online. Distributed generators (DGs) such as solar PV, wind turbines, small combined heat and power (CHP) units, energy storages, demand response (DR) and energy efficiency programs all fall into the DER category. Such active energy resources have been significantly changing the landscape of traditionally passive distribution grids. New challenges present significant threats for which traditional Distribution Network Operators (DNOs) are not accustomed. These challenges include, such as reverse power flows on feeders with high DER penetration, over/under voltage problems at the connection points of DERs, overloads on feeders with microgrids and other types of dynamically-changing loads, along with other violations of technical constraints.
    This talk addresses how traditional DNOs are required to swiftly transform into more involved operators – Distribution System Operators (DSOs) and challenges and opportunities associated with the new tools and capabilities to manage such complex systems as the emerging distribution grids.
