Identification of requirements for distribution management systems in the smart grid context

Abstract

Abstract-The integration of significant volumes of distributed and renewable energy resources directly connected to the distribution network raises new requirement to maintain and operate the power system in secure state. Thus the Distribution Management System (DMS) needs to be updated and integrated with new functionality to provide effective support for the operators. The DMS is a control center solution that provides the needed functionality for the management of medium and low voltage distribution networks. This paper aims to provide an overview of the main functions present in today´s DMS platforms and to identify the new requirements to better serve in a smart grid context. Index Terms-active distribution networks, distribution management system, frequency control, smart grid, synthetic inertia.

Reduction of topological connectivity information in electric power grids

“…A cell can be defined as a group of interconnected generation, load and storage, all within well-defined grid boundaries corresponding to a physical section of the grid. Neighboring cells are connected via tie-lines [12].…”

Electric power system inertia: requirements, challenges and solutions

“…ELECTRA considers the grid inertia (i.e. synchronous and emulated inertia) as an active part of the frequency control process [9,10].…”

Validating a centralized approach to primary frequency control with series-produced electric vehicles

“…For instance, in the ELECTRA project, innovative control schemes are being investigated in order to assess whether conventional frequency and voltage controlling approaches are still suitable, or which aspects need to be revised for scenarios with massive amounts of small distributed energy resources [1,2]. It is argued that TSOs alone will not be able to effectively manage the overall system balance and will have to partially delegate frequency control responsibility to DSOs as already happens today for congestions management and volt-reactive power provision [3][4][5][6][7][8][9][10].…”
