Factors Affecting Values of Short-Circuit Current Levels in Electrical Power Engineering Systems
Известия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2003 Short-circuit current levels in power networks with various voltage class are characterized by probabilistic nature. They are discretely changeable, depend on a number of factors and have a significant importance while selecting electric equipment, a ...

Distributed Adaptive Droop Control for DC Distribution Systems [PDF]
, 2014 A distributed-adaptive droop mechanism is proposed for secondary/primary control of dc Microgrids. The conventional secondary control, that adjusts the voltage set point for the local droop mechanism, is replaced by a voltage regulator.

A Novel Decomposition for Control of DC Circuits and Grid Models with Heterogeneous Energy Sources [PDF]
, 2017 The way in which electric power depends on the topology of circuits with mixed voltage and current sources is examined. The power flowing in any steady-state DC circuit is shown to depend on a minimal set of key variables called fundamental node voltages

Multi-objective partition planning for multi-infeed HVDC system
Global Energy Interconnection, 2021 The close proximity and the necessity of coordination between multiple high-voltage direct currents (HVDCs) raise the issue of grid partitioning in multi-infeed HVDC systems. A multi-objective partition strategy is proposed in this paper.
