dc.description.abstract | Sustainable smart buildings play an essential role in terms of more efficient energy.
However, these buildings as electric loads are affected by an important distortion in the current and
voltage waveforms caused by the increasing proliferation of nonlinear electronic devices. Overall,
buildings all around the world consume a significant amount of energy, which is about one-third of
the total primary energy resources. Optimization of the power transfer process of such amount of
energy is a crucial issue that needs specific tools to integrate energy-efficient behaviour throughout
the grid. When nonlinear loads are present, new capable ways of thinking are needed to consider
the effects of harmonics and related power components. In this manner, technology innovations are
necessary to update the power factor concept to a generalized total or a true one, where different
power components involved in it calculation, properly reflect each harmonic interaction. This work
addresses an innovative theory that applies the Poynting Vector philosophy via Geometric Algebra
to the electromagnetic energy transfer process providing a physical foundation. In this framework,
it is possible to analyse and detect the nature of disturbing loads in the exponential growth of
new globalized buildings and architectures in our era. This new insight is based on the concept
of geometric objects with different dimension: vector, bivector, trivector, multivector. Within this
paper, these objects are correlated with the electromagnetic quantities responsible for the energy flow
supplied to the most common loads in sustainable smart buildings. Besides, it must be considered
that these phenomena are characterized by a quality index multivector appropriate even for detecting
harmonic sources. A numerical example is used to illustrate the clear capabilities of the suggested
index when it applies to industrial loads for optimization of energy control systems and enhance
comfort management in smart sustainable buildings. | es |
