In this paper, a pricing alternative based on the scheme of Time of Use Pricing (TOUP) is proposed for customers connected to the Cooperativa Eléctrica San Pedro de Atacama (CESPA) microgrid, located in the far north of Chile. With this proposal, the promotion of Demand-Side Management, DSM, aims at optimizing both the use of electric energy and th...
Article
There are multiple technologies for transporting info-communications between objects and machines for the internet. Two of the most robust and with the highest coverage and support for multiple users are 4G and WiMax IEEE 802.16x. This paper presents a simulation of land coverage of both wireless communication technologies as a broadband communicat...

Energy efficiency is part of the goals set by governments around the world to reduce the energy footprint and provide sustainable development for all. The arrival of new technologies that allow the monitoring and self-control of electricity consumption within homes, such as smart meters, allow end users to integrate into the intelligent management...
Article
For an efficient energy management by residential users, monitoring and control of connected household appliances is required. If the consumption pattern of each of these devices is identified, then the management will be more efficient, reducing both the billing and the CO2 emissions. This paper proposes a model for the recognition of energy consu...

One of the main challenges in smart city models is consumer behaviour, namely guiding the efforts to promote optimal use of energy in the dynamics of the developing cities, through lower energy consumption without impact on the comfort level. This relates to all energy vectors and can be done through different means. The uptake stage of smart meter...
Article
The communication technologies applied in solutions with Wireless Sensor Networks, Internet of Things, and Machine to Machine are the fundamental pillars for a scenario considering energy management. This workfocuses on applications for the achievement of Smart Cities that hope to prioritize the quality of life through applications of Information T...

Abstract— This paper presents a novel application to predict the electric load one day ahead with online implementation and self�control. Methodologically, is based on three different stages. The first one involves the selection of the best ARIMA models for each hour of the day, using a particle swarm optimization algorithm. Before this, the re...

The efficient use of energy and its implementation in domestic automation systems is an essential requirement in Smart Cities. However, this requires appropriate measurement devices and an M2M control-communication alternative that offers real-time visualization of the information. This article proposes a prototype of the home electric power consum...

In this work, Space-Time Block Coding (STBC) applied to improve performance of High Altitude Platforms (HAPs) for radio links is analysed. The communications scenario considers an aeronautical channel similar to the land mobile satellite channel model proposed in [6] which offers for medium and low angles of elevation from the ground station (worse...

Resumen El presente artículo resume aspectos relevantes del diseño e implementación de antenas helicoidales para la banda de 2.4 GHz y los enlaces inalámbricos definidos para el modelo de cobertura del proyecto HAPS 1 . Se presentan y aplican los elementos teóricos para el diseño de las antenas y se contrastan los resultados obtenidos a través de m...
Article

In this paper, the predictions and adaptation of faded aeronautical channels induced by impaired weather will be presented. The signal variations due to rain fading are generally much slower than variations due to multipath and shadowing. This is a principal problem in means of propagation for stratospheric platforms at High Altitude Aeronautical P...

This paper considers the analysis by simulation of a digital narrowband communication system for an scenario which consists of a High-Altitude aeronautical Platform (HAP) and fixed/mobile terrestrial transceivers. The aeronautical channel is modelled considering geometrical (angle of elevation vs. horizontal distance of the terrestrial reflectors)...

In this paper, BER performances are obtained by simulation for Ka-band in High Altitude Platforms Stations (HAPS) channel model incorporating weather effects (rain). A channel model based on Whenzen and Lutz proposals about land mobile satellite is discussed for two propagation states and a first approach is followed for an interesting situation.

The following paper proposes a model of frequency re-use for the 2.4 GHz ISM band, under the 802.11x standard applied in Low Altitude Platforms (LAPs). The proposed scheme is implemented in order to counteract the harmful effects of the antenna gain sidelobes profile over the Carrier to Interference Ratio (CIR). Finally, some worksite results are s...
