The electric transmission system is the infrastructure that allows the transfer of energy from the production points to the consumption centers. It has the characteristic of regulated natural monopoly. For efficiency and economic equity in the electricity market, it is necessary that both the electrical losses and the costs incurred in the transmission process be properly distributed among all the agents that make use of this system. That is why around the world a series of methodologies have been developed that allow the regulators of the electrical system to set the transmission rates that assure their owners to recover the costs incurred in the construction, operation and maintenance and allow the efficient development of the Long-term network. In this context, this article reviews the different methodologies for assigning electrical losses and transmission costs at national and inter...

This article has the objective to develop the general framework, previous knowledge and the analysis of the more important aspects related to the controversy that presents the collision of rules between a Connection Order, issued by the Osinergmin, and a Contract of the Guaranteed Transmission System, signed by the Peruvian state and a transmission licensee; that indeed present a unique situation in the energetic policy field.

The transmission plan includes binding projects approved by the Ministry of Energy and Mines, which must be implemented over a 10-year period to ensure the quality, safety and efficiency of the national electricity system. This planning is carried out within the framework of the state duty to ensure the efficiency and continuity of the electricity supply. This document evaluates the criteria of generality, innovation and consumption to determine whether the transmission plan is a normative or administrative act. The general character of the plan is reviewed in accordance with these criteria, which does not necessarily determine whether it is a rule or an administrative act, since there are acts that have a general character and rules with particular application. The plan is also derived from a law, but requires other acts to be implemented. Finally, the plan is ended by fulfilling its pu...

High penetration of renewable energy sources (RES) leads to new challenges for protection devices. Protection schemes are typically designed according to the dynamic behavior of rotating machines as generation sources, while the RES dynamic response, mainly governed by inverters, is not considered. Consequently, some relevant algorithms of transmission line protection are experiencing challenges because of the fact that magnitude and phase angle com parison, amount of negative-sequence, and short-circuit current level are affected by the RES. Therefore, an in-depth study of this issue is necessary, one which considers the main causes and new methodological criteria solutions. This work presents an extensive literature review of the evaluation of electrical protection performance and the effects of RES connected to a power grid through inverters. Bibliographic data on many representative ...

The main objective on this research is the development of finding the optimal parameters for a routing algorithm for network routers based on the ant algorithm described as AntNet. The optimum parameters for this type of algorithm improve a more efficient alternative to those given by the RIP, EIGRP and OSPF routing protocols, to be applied in a data network. This shall be tested in two networks and routers defined, taking the same characteristics for the three groups: RIP, OSPF and by the result provided by the genetic algorithm implemented using a static network. The system recognizes the best path between networks of routers, based on the principle of AntNet networks or networks of ants, which are the best way from exploring almost all roads, using estimergia to go there and make optimal. MatLab was used to detect the best way. Later this road was implemented in a real network data, s...

The relation between media and society imply constant interaction. This on going and dynamic interaction is described and explained by the framing theory. Though many authors have written on the matter, the present work makes a new contribution: it systemizes academic production and delivers an integrated outlook of the transmission process. As a matter of fact, media transmits and redefines social dialogue while influencing the perspective from where they present and define issues of public debate.

The Unified power flow controller (UPFC) is the most important contribution of the power electronics in the modern Electrical Power Systems. The UPFC is able to decouple the control of the active and reactive power sent trough the transmission line. This control is performed byinjecting in series with the transmission line a voltage with regulated magnitude and phase, generated by a PWM voltage source inverter (VSI). When the current flow in the line originate in the inverter an active and reactive power. The active part of the power require to be eithersupplied or absorbed by a device, e.g. a second inverter. In this paper, simulation result obtained with a fundamental model of UPFC connected to a simple AC transmission system, and a control system base on "dq" transformation necessary to obtained the P and Q decoupled control ispresented.

In this article we study the wave propagation over materials consisting of two components: one component is simple elastic while the other has a nonlinear internal dampingwith elastic coefficients dependent on time; both components having source terms. Byusing the potential well method we obtain the global existence, we also show that theenergy of the system decays uniformly to zero,

In this paper, we consider a modified SIR model, implementing a population of Pathogens interacting with a human population of Susceptibles, with which we will have 4 ordinary differential equations in our system. The objective of this work is to analyze the stability of the disease free point (local and global) and the endemic equilibrium point (local) of this mathematical model. In addition, numerical simulations to the model are presented to contrast the effects of nonlinear transmission rates and other parameters.

Introduction: The elimination of malaria is the definitive solution to prevent the growing resistance to drugs and insecticides from threatening the progress made since the beginning of the 21st century. Objective: To analyze the spatio-temporal characteristics of malaria transmission in the Loreto region. Methods: We carried out a time series study, and the weekly incidence of malaria in Loreto in the last 20 years (2000-2019) was analyzed using data from the Epidemiological Surveillance System of the Ministry of Health. With this information, we modeled the weekly incidence of malaria across the Loreto surveillance reporting units and determine its spatio-temporal characteristics at the macro and micro-regional levels. Additionally, we characterized the “hot zones” and their stability over time. Results: During the last 20 years, we observed that Loreto has a seasonal malaria trans...

In this research is analyzed COVID-19 transmission by thermodynamic and energy balance between geographic areas and its correlation with possible COVID-19 transmission between 2 persons at least. In order to achieve parameters for medical doctors, as for example the minimal distance among two infected people, who have this virus, there were designed mathematical models that were based in statistical data to get information of COVID-19 propagation as the dependence on temperature of geographic areas, moreover the thermal effect of the minimal distance between two people avoiding COVID-19 infection. With this work, answers are sought to the questions: if it could be possible to find a relation between temperature and virus transmission? Or if it could be possible to get a correlation variable among thermal variables with minimal distance separation (it was described above) for two people? ...
