Dynamic Transmission Expansion Planning (DTEP) seeks to answer where, how many, and when new infrastructure should be added the electrical system. The goal is allow a correct efficient operation along planning horizon. In this research work, load shedding formulation extended for multistage alternating current (AC) model with co-optimization of shunt compensation proposed. A novel hybrid meta-heuristic used as optimization technique solve DTEP problem. Solutions were obtained from IEEE...

Then, vector possible disorders used as input Type-2 Fuzzy Logic System. way, obtained expressed in words easy understand by maintenance personnel. efficiency has been tested with field data bibliography. validity shown means an example.

During the solar eclipse of August 21, 2017, Honduras's electric power grid operation experienced changes. In this work, evidence impact on generation was found. Although in country partial, with only 28.9% photosphere's darkening, electrical system affected, mainly because 409 MW photovoltaic are installed country's system. It is equivalent to approximately 17% capacity. Hence, an over cost due re dispatch during Due results, it noted that coming eclipses will have a greater Honduras and...

This paper develops and analyzes four energy scenarios for Colombia that consider the El Niño phenomenon inclusion of renewable energies in generation matrix period 2020–2035. A comparative analysis is presented between results different proposed. The most relevant finding use reserve margin as an indicator system reliability. scenario which included 7214 MW large-scale non-conventional energy, 10,000 distributed generation, 12,240 hydroelectric power was assumed, with a over 50%....

Central America is electrically interconnected from Panama thru Guatemala by a 230 kV electric power transmission line with committed capacity among countries of 300 MW. Due to its radial configuration and set constraints in the equipment, network prone collapse case occurrence some disturbances. Generally, these disturbances occur one drag whole American system regional failures. For this reason, implementation protection systems that avoid grid necessary. Hence, work simulation results...

In view of having a precarious public health system, the Honduran population is with needed to find alternatives meet their needs, this particularly important for people physical disabilities. For San Felipe Public Hospital, which center country's largest prosthesis it impossible demand, about 1,800 per year requiring prosthetic limb, only in center. addition high demand and shortage materials, dedicated exclusively production above below knee prosthesis, leaving aside patients whose...

The Central American Power System (CAPS) comprises of the electrical power networks Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica and Panama. topology network, geographical distribution load generation blocks, localized weaknesses in some sections transmission grid have made this system prone to frequent partial or total blackouts. At same time, area has advantage having a control center that can promote international measures order safeguard integrity network. This paper presents...

Honduran coffee is one of the best coffees worldwide. Its cultivation and subsequent quality control require use expert cuppers. In this work a fuzzy logic type-2 system used as tool to obtain level cup based on subjective criteria by A case shown prove effectiveness system. The was tested in more than 500 cases which 97% time cuppers agreed with results

The Regulatory framework of the Central American Electricity Market is based on Treaty implementation, its two protocols and Regional Regulation. In latter, way market should operate, both technically commercially, established. regulation also creates regional organizations to allow operation electricity in America. This document shows a broadly legislation that allows organizational structure main agencies Finally, some conclusions are shown structure.
