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.

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.

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.

What is a hybrid solar-wind system?

Solar systems are a mature technology, used to power some remote BTSs for many years, replacing the expensive to run diesel generators. Hybrid solar-wind systems use two renewable energy sources, improving the system efficiency and reducing the energy storage requirements .

When should a BTS hybrid system be cooled?

Particularly, we suggest that (i) when the produced energy of the BTS hybrid system exceeds consumption and the batteries are full, the surplus of energy should be used to cool the BTS up to a lower temperature, and (ii) when the produced energy is not enough, consumed energy on the air condition could be eliminated.

Can a BTS be used as a backup to a hybrid system?

The majority of the BTSs already has a diesel generator, which can also be used as a backup to the hybrid system, reducing the installed size of the described wind/PV/battery system. At the same time, grid connection could be used as a back up too, when possible.
