Short-term expansion planning of radial electrical distribution systems using mixed-integer linear programming
(Inst Engineering Technology-iet, 2015-02-19)
This study presents a mixed-integer linear programming (MILP) model to solve the short-term expansion planning problem of radial electrical distribution systems. The proposed model defines the construction of new circuits, ...
Planeamiento de la expansión de la red de transmisión en sistemas eléctricos de potencia considerando reconfiguraciones de red
(2014-01-01)
In this paper the necessary equations for considering existing network reconfiguration in the disjunctive linear model used to solve the problem transmission expansion planning. In the traditional methods used for solving ...
Energy generation expansion planning model considering emissions constraintsmodelo de planeamiento de la expansión de la generación considerando restricciones de emisiones
(2010-01-01)
The generation expansion planning (GEP) problem consists in determining the type of technology, size, location and time at which new generation units must be integrated to the system, over a given planning horizon, to ...
Transmission network expansion planning considering repowering and reconfiguration
(Elsevier B.V., 2015-07-01)
Transmission expansion planning (TEP) is a classic problem in electric power systems. In current optimization models used to approach the TEP problem, new transmission lines and two-winding transformers are commonly used ...
A constructive heuristic algorithm for multi-stage transmission expansion planning under N-1 security constraints
(2015-04-01)
The transmission expansion planning (TEP) problem in modern power systems is a large-scale, mixed-integer, non-linear, and non-convex problem. The problem becomes even more complicated when the security constraints are ...
Expansivity and shadowing in linear dynamics
(Elsevier B.V., 2018-05-01)
In the early 1970's Eisenberg and Hedlund investigated relationships between expansivity and spectrum of operators on Banach spaces. In this paper we establish relationships between notions of expansivity and hypercyclicity, ...
VAr planning using genetic algorithm and linear programming
(2001-05-01)
A combined methodology consisting of successive linear programming (SLP) and a simple genetic algorithm (SGA) solves the reactive planning problem. The problem is divided into operating and planning subproblems; the operating ...
Flexible Solution Approach for Multistage Transmission Network Expansion Planning with Multiple Generation Scenarios
(Springer, 2020-04-15)
One of the approaches to represent competitive market rules, uncertainties in the generation, and different seasonal climatic conditions in the multistage transmission network expansion planning problem is through ...
Coeficiente de dilatación : diseño y construcción de un dilatómetro
(Universidad Nacional del Nordeste. Facultad de Ciencias Exactas y Naturales y Agrimensura, 2021-05-06)
En prácticamente cualquier curso de termodinámica aparece el tema de dilatación, en particular la dilatación lineal. Pero también resulta de mucha importancia en la naturaleza ya que ésta se toma muy seriamente el tema al ...
