Optimal Power Flow on DC Microgrids: A Quadratic Convex Approximation
(Institute of Electrical and Electronics Engineers Inc., 2019)
This express brief shows a convex quadratic approximation for the optimal power flow (OPF) in direct-current microgrids (dc-μ Grid) via Taylor's series expansion. This approach can be used for solving OPF problems on radial ...
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 ...
Modeling and control of a small hydro-power plant for a DC microgrid
(Elsevier Ltd, 2020)
This paper presents the modeling and control of a small hydro-power plant (SHP) for a DC microgrid based on passivity theory. The SHP is made up of a turbine, a permanent magnet synchronous generator (PMSG), a voltage ...
A Sequential Quadratic Programming Model for the Economic-Environmental Dispatch in MT-HVDC
