A quadratic convex approximation for optimal operation of battery energy storage systems in DC distribution networks
(2021-11-07)
This paper proposes a quadratic convex model for optimal operation of battery energy storage systems in a direct current (DC) network that approximates the original nonlinear non-convex one. The proposed quadratic convex ...
A Convex OPF Approximation for DC Networks Considering Voltage-Dependent Load Models
(2020-12-01)
This paper addresses the problems of power flow and optimal power flow analysis considering voltage-dependent load models from the convex point of view. First, Taylor series expansion method is employed for linearizing the ...
Voltage stability margin in DC grids with CPLs: A recursive Newton-raphson approximation
(2019-03-11)
This express brief addresses the voltage collapse problem in direct-current (dc) networks by using a recursive heuristic search algorithm based on the Newton-Raphson method. The determinant of the Jacobian matrix in the ...
Power quality detection and classification using wavelet and support vector machine
(2019-09-24)
This work presents the identification and classification of various disturbances that affect the quality of energy, seen as the quality of the voltage wave (harmonics, sag, swell and flicker). For this, the wavelet transform ...
