Optimal Selection and Integration of Batteries and Renewable Generators in DC Distribution Systems through a Mixed-Integer Convex Formulation
(Cartagena de Indias, 2022-09-30)
The problem concerning the optimal placement and sizing of renewable energy resources and battery energy storage systems in electrical DC distribution networks is addressed in this research by proposing a new mathematical ...
A two-stage approach to locate and size PV sources in distribution networks for annual grid operative costs minimization
(Cartagena de Indias, 2022-03-21)
This paper contributes with a new two-stage optimization methodology to solve the
problem of the optimal placement and sizing of solar photovoltaic (PV) generation units in mediumvoltage distribution networks. The ...
Optimal shutdown policy for maintenance of cracking furnaces in ethylene plants
(American Chemical Society, 2006-04)
This work addresses the cyclic scheduling of cracking furnace shutdowns in ethylene plants within a short-term production planning model, based on a discrete time representation. Cracking furnaces are continuous parallel ...

Optimal Power Flow with Renewable Generation: A Modified NSGA-II-based Probabilistic Solution Approach
(2020-08-01)
The rapid expansion of renewable generation has drastically increased the planning complexity of modern power systems as additional uncertainties, environmental concerns, and technical–economic issues should be accounted ...
Energy-efficient channel estimation
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
We investigate the energy-efficient channel estimation in wireless networks, where one pilot is inserted for every several data slots to estimate the channel coefficients. Both the channel state information estimation error ...
Minimization of life cycle greenhouse emissions and cost in the operation of steam and power plants
(Elsevier, 2008-06)
The main objective of this work is to use environmental and economic objective functions to select the operating conditions of process plants. The operating conditions of a steam and power plant are selected to minimize ...
