Integration of utility distributed energy resource management system and aggregators for evolving distribution system operators
Open accessAbstract
With the rapid integration of distributed energy resources (DERs), distribution utilities are faced with new and unprecedented issues. New challenges introduced by high penetration of DERs range from poor observability to overload and reverse power flow problems, under-over-voltages, maloperation of legacy protection systems, and requirements for new planning procedures. Distribution utility personnel are not adequately trained, and legacy control centers are not properly equipped to cope with these issues. Fortunately, distribution energy resource management systems (DERMSs) are emerging software technologies aimed to provide distribution system operators (DSOs) with a specialized set of tools to enable them to over-come the issues caused by DERs and to maximize the benefits of the presence of high penetration of these novel resources. However, as DERMS technology is still emerging, its definition is vague and can refer to very different levels of software hierarchies, spanning from decentralized virtual power plants to DER aggregators and fully centralized enterprise systems (called utility DERMS). Although they are all frequently simply called DERMS, these software technologies have different sets of tools and aim to provide different services to different stake-holders. This paper explores how these different software technologies can complement each other, and how they can provide significant benefits to DSOs in enabling them to successfully manage evolving distribution networks with high penetration of DERs when they are integrated together into the control cen-ters of distribution utilities.

DERMS integrates diverse stakeholders through a hierarchical framework and supports core capabilities such as translation, aggregation, simplification, and optimization, enabling effective management of large-scale DERs.
“DERMS integrates diverse stakeholders through a hierarchical framework and supports core capabilities such as translation, aggregation, simplification, and optimization, enabling the effective management of large-scale DERs.”
From Improving distribution system flexibility using electric vehicles under the distributed energy resource management system framework (2026) · cites this paper as [3]
Section B, “Roles and Responsibilities of DER Management Solutions” (page not provided), describes utility DERMS and DER aggregators as different levels in a hierarchy and says they can jointly manage DERs through aggregation and optimization. Section C, “Integration of Utility DERMS and DER Aggregators: an Ideal Case” (page not provided), discusses managing systems with high DER penetration. The copy does not identify translation or simplification as core capabilities, and its hierarchy is of management solutions rather than stakeholders. (LLM, conf=0.85)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
