Methodological approach for defining frequency related grid requirements in low-carbon power systems
(IEEE, 2020)
Moving towards low-carbon electricity systems through the massive deployment of
renewable energy sources (RES) presents a unique opportunity to combat climate change, but it also poses
enormous technical challenges, ...
Mathematical decomposition technique applied to the probabilistic power flow problem
(2011-05-31)
In this paper a framework based on the decomposition of the first-order optimality conditions is described and applied to solve the Probabilistic Power Flow (PPF) problem in a coordinated but decentralized way in the context ...
Disturbing Load Classification Based on the Grey Relational Analysis Method and Load Performance Index
(2020-02-01)
This paper proposes an approach based on grey relational analysis to analyze and classify potentially disturbing loads taking into account the power factor, unbalance, harmonics and reactive power. By computer simulations, ...
Harmonic, reactive and unbalance compensation by means of CPT framework
(2009-12-01)
This paper presents possible selective current compensation strategies based on the Conservative Power Theory (CPT). This recently proposed theory, introduces the concept of complex power conservation under non-sinusoidal ...

From Power-over to Power-to: Power Relations of Women in Hansberry’s A Raisin in the Sun
(Impossibilia, n.4, p. 34-51, Oct., 2012, 2012-10-31)
Because of binary oppositions shaping Western thought, power has been traditionally understood as male domination or as an unevenly distributed social resource between genders. However, an analysis of the power relationships ...

Power Quality Study and Analysis of Different Arc Welding Machines
(2018-04-01)
Electrical welding machines are among the most pollutant loads due to their strong nonlinear behavior. As a result, utilities have established new criteria for connecting welding machines in the grid. One approach that can ...
