Direct power control for VSC-HVDC systems: An application of the global tracking passivity-based PI approach
(Elsevier Ltd, 2019)
This paper proposes a direct power control (DPC) for a high-voltage direct-current system using voltage source converters (VSC-HVDC) by applying passivity-based control theory. This system allows doing an efficient and ...
Power flow approximation for DC networks with constant power loads via logarithmic transform of voltage magnitudes
(Elsevier Ltd, 2019)
This paper proposes a logarithmic transformation of voltages (LTVM) for the power flow in DC grids. This problem is non-linear due to the presence of constant power loads (CPLs), which also introduce a negative resistance ...
Control for EESS in Three-Phase Microgrids under Time-Domain Reference Frame via PBC Theory
(Institute of Electrical and Electronics Engineers Inc., 2019)
This brief presents a general form of designing passivity-based controllers for electrical energy storage systems (EESS) in three-phase microgrids (TP-MGs) under time-domain reference frame. The control strategy proposed ...
Distributed energy resources integration in single-phase microgrids: An application of IDA-PBC and PI-PBC approaches
(Elsevier Ltd, 2019)
This paper presents a unified Hamiltonian formulation for controlling distributed energy resources (DERs)in ac single-phase microgrids (SP-MGs)via proportional-integral passivity-based control (PI-PBC), and interconnection ...
Output Voltage Regulation for DC-DC Buck Converters: A Passivity-Based PI Design
(Institute of Electrical and Electronics Engineers Inc., 2019)
This paper presents a global tracking passivity-based proportional-integral (PI) control for output voltage regulation of a DC-DC Buck converter. The proposed controller is based on passivity formulation since DC-DC Buck ...
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)
This paper proposes a passive PI control for applications of photovoltaic (PV) systems integrated with boost DC-DC converters. The proposed controller guarantees asymptotically stability in closed-loop for the boost DC-DC ...
Controller design for VSCs in distributed generation applications: An IDA-PBC approach
(Institute of Electrical and Electronics Engineers Inc., 2019)
This paper presents an asymptotically stable global controller design for distributed energy integration in electrical distribution networks using a three-phase voltage source converter (VSC). An invariant Park's transformation ...
