Energy saving in wind and solar hybrid construction of communication base stations

What is a hybrid solar/wind based power system?

A hybrid solar/wind based power system comprises PV array, wind turbine, battery bank, controller, inverter, cabling, and other devices (such as fuses etc.). The layout of a BS employing conventional as well as renewable energy sources is shown in Fig. 5.

How to make base station (BS) green and energy efficient?

This paper aims to consolidate the work carried out in making base station (BS) green and energy efficient by integrating renewable energy sources (RES). Clean and green technologies are mandatory for reduction of carbon footprint in future cellular networks.

Can a hybrid system reduce the operational costs of BTS?

In this paper, we presented a hybrid system, which uses renewable energy sources (solar and wind energy), diesel power and the electric grid. This system has been optimized for minimizing the operational costs of BTS, while promising high reliability.

Do hybrid power systems reduce the cost of isolated power systems?

The hybrid systems comprising conventional and RESs have been shown to significantly decrease the overall cost of the isolated power systems over their total life cycle ( Karki and Billinton, 2001 ).

Is hybrid energy system a cost-effective option for re-Mote and grid-connected BTS?

According to numerical results, for the use case of the Greek island of Kea, we confirmed that hybrid energy system is a promising, cost-effective option for both re-mote and grid-connected BTSs, via reducing remarkably the total annualized cost of energy system and CO2 emissions.

How to optimize a hybrid energy system?

In order to select an optimum com-bination for a hybrid system to meet the load demand, evaluations must be carried out on the basis of power reliability and system life-cycle cost. Recently, several simulations have been performed in order to optimize hybrid energy systems and to fulfill the energy demands of a BTS.
