ogsåLikestrømsystemer

OgsåLikestrømsystemer is a term used in power engineering to describe a class of distribution architectures that aim to maintain uniform current sharing among multiple parallel sources and loads connected to a common electrical bus. The concept emphasizes balance of current across devices rather than focusing solely on voltage regulation, with the goal of preventing current hogging by any single source and improving redundancy and reliability in distributed energy resources.

Practically, ogsåLikestrømsystemer are achieved through a combination of symmetric impedance design, active current-sharing controllers, and, where needed, limited inter-unit communication between modules. Controllers may implement droop control or virtual-impedance strategies to distribute currents proportionally to each source’s rating, while digital processors monitor real-time currents and voltages to stabilize the system and detect asymmetries or faults. The approach seeks to preserve stable operation under varying loads and resource conditions, including during transitions between generation modes or fault events.

History and development of the concept come from academic discussions and pilot studies in distributed energy resources, microgrids, and high-density data-center power architectures. The term is used to describe an engineered objective rather than a single standardized technology, with implementations often combining power-electronics design, control theory, and communication layers.

Applications and benefits include improved redundancy, smoother transient responses, and more predictable current distribution in systems with multiple converters or generators. Challenges involve higher design complexity, stability margins under dynamic conditions, and the need for reliable communication and protective coordination.
