Procedure to select the optimised power architecture for a telecommunications network of remote units

Abstract

Telecommunications equipment are moving from the large Central Offices where the source of energy (AC Mains or DC batteries) is accessible towards more distributed equipment along the network where AC Mains can not be accessible. To supply energy in an optimum way to these equipment, called Remote Units, is a new challenge for telecommunication companies affecting this selection to the cost and reliability of the overall telecom system. The target of this paper is to propose a procedure to select the most suitable solution from the cost point of view.

Experimental Analysis of a Standalone Renewable Energy Based Hybrid System

“…The present work is a step further for the creation of reliable, sustainable and environmental friendly ways of providing energy without a grid connection. This is particularly useful for applications in remote places, such as, for instance, radio base stations, where to provide a grid connection can be quite expensive and the conventional gensets might have unwanted additional maintenance costs [2]. Therefore, the study of power electronic converters for these systems contributes to the growth of economic value [2].…”

“…To increase the reliability of such systems, different types of generators and energy storage components can be combined for an autonomous energy supply. Usually named as standalone power systems [1], their reduced need of maintenance and fuel-free operation makes them attractive for a great number of applications, especially in remote areas, where providing a grid connection can be highly expensive or even unfeasible [2]. Optimization of their sizing, simulation models and energy management are the greatest issues focused by research to improve the performance of these systems [3][4][5].…”

A comprehensive review of distributed power system architecture for telecom and datacenter applications

“…As the number of power stages is more with traditional distribution system, the research has been progressing for an alternative solution to reduce the power conversion stages. It helps to increase the system efficiency and reliability by using the alternate distribution voltage [12]. Traditionally, the power distribution for the data centers is AC voltage and for the telecommunication facilities the power distribution is 48V DC [13].…”

Power converters analysis in a renewable energy based hybrid system with hydrogen storage

“…Power converters play a fundamental role in renewable energy based standalone power systems, especially if they are supplying critical loads in remote places like telecommunications equipment [1]. They are responsible for conditioning the intermittent and variable energy supplied by the generators, such as photovoltaic arrays and wind turbines, according to the equipment requirements, which include not only supply continuity, safety and long life, but also technical issues like the supply voltage acceptable range [2].…”
