Linear power flow formulation for low-voltage DC power grids
(Elsevier Ltd, 2018)
This paper presents a reformulation of the power flow problem in low-voltage dc (LVDC) power grids via Taylor's series expansion. The solution of the original nonlinear quadratic model is achieved with this proposed ...
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 ...
Passivity-based PI control of a SMES system to support power in electrical grids: A bilinear approach
(Elsevier Ltd, 2018)
A bilinear proportional-integral (PI) controller based on passivity-based formulations for integrating superconducting magnetic energy storage (SMES) devices to power ac microgrids is proposed in this paper. A cascade ...
Optimal conductor size selection in radial distribution networks using a mixed-integer non-linear programming formulation
(IEEE Computer Society, 2018)
In this paper a mixed-integer non-linear programming formulation for optimal conductor selection in radial distribution networks is proposed. The objective function in this problem corresponds to the minimization of power ...
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 ...
Optimization of a drive shaft using PSO algorithm
(World Scientific and Engineering Academy and Society, 2018)
