Active and reactive power conditioning using SMES devices with PMW-CSC: A feedback nonlinear control approach
(Ain Shams University, 2019)
The active and reactive power conditioning using superconducting magnetic energy storage (SMES) systems for low-voltage distribution networks via feedback nonlinear control is proposed in this paper. The SMES system is ...
On the nonlinear control of a single-phase current source converter for sinusoidal voltage generation
(2020)
Colombian power system is being transformed for the large-scale integration of renewable energy resources and energy storage systems; all of these are integrated by power electronic converters controlled by voltage and ...
Toward an adaptive protection scheme in active distribution networks: Intelligent approach fault detector
(2021-01)
Conventional protection schemes have proven insufficient for the protection of Active Distribution Networks (ADN). Novel protection schemes with an adaptive approach should be developed to guarantee the protection of ADN ...
A Sequential Quadratic Programming Model for the Economic-Environmental Dispatch in MT-HVDC
(Institute of Electrical and Electronics Engineers Inc., 2019)
This paper addresses the economic-environmental dispatch problem for thermal plants on a Multi-terminal HVDC power grid. A multi-objective optimization approach is used for modeling the compromise between fuel costs and ...
Direct power control of electrical energy storage systems: A passivity-based PI approach
(Elsevier Ltd, 2019)
This paper proposes a direct power control for electrical energy storage systems (EESS) in ac microgrids. This strategy allows managing instantaneous active and reactive power without using a conventional inner-loop current ...
Current PI Control for PV Systems in DC Microgrids: A PBC Design
(Institute of Electrical and Electronics Engineers Inc., 2019)
