Mobile operators are deploying energy-harvesting heterogeneous networks due to their foreseen advantages such as self-sustainable capability and reduced operating expenditure, which cannot be offered by conventional grid powered communications. However, the used energy storage is subject to irreversible aging mechanisms, requiring intelligent management that considers both the energy cost and battery life cycle. In this paper, we propose a cognitive energy management strategy for small cell base stations powered by local renewable energy, a battery, and the smart grid to simultaneously minimize electricity expenditures of the mobile operators and enhance the life span of the storage device. Non-linear battery models and aging processes are considered to formulate the energy cost optimization problem. Simulation results in different configurations show that a degradation-aware policy significantly improves the battery lifetime, while achieving considerable cost savings.

“…This assumption is supported by [11], [12] and [16]. Taking these assumptions into account the probability for the existence of a remote communication channel between the TSO head-quarter and field personnel at a time, t, after a black out can be approximated with equation 2, where L(t) is the load at a BTS.…”

“…The consequence of this is that a efficient restoration of a power system is heavily depended in batteries as backup power. One of the most common type of battery used for backup power purposes is the lead-acid battery, because it is a cheap alternative and has a long life, see [10], [11] and [12]. Another common battery is the Nickel-Cadmium battery.…”

Abstract-A large scale blackout is a long term loss of electricity over a large geographical area. In order to succeed with the restoration, the electric utility SCADA system must be highly reliable not only in normal operation but also during a black out. The main contribution of this paper is a circuit breaker (CB) reliability model to be used in restoration planning. The model consider both the reliability of a SCADA system and the reliability of a communication system during a power outage. If a remote control of CB fails, due to battery undersizing, it is assumed in the paper that a manual operation of CB can be performed if field personal can communicate with the TSO head-quarter. The evaluation of the reliability to operate CB is performed by solving the so called s-t reliability problem for a graph with failure prone components. The method is applied in a case study where the SCADA architecture for an IEEE reliability test system is modeled.

“…Whereas low transmission loss microstrip feeds can occasionally be utilised within the antenna to provide amplitude and phase distributions between the elements [3], they usually have limited operation bandwidth [4] and for obvious practical and logistical reasons cannot be used between the antenna and BTS. Furthermore, as energy prices and environmental awareness increases [5], there is a distinct commercial requirement to reduce the power consumption of the BTS by improving its efficiency [6].…”

This paper presents fibre-to-air, a new system for feeding radio frequency (RF) signals from either the base station controller (BSC) or base transceiver station (BTS) directly to the antenna element at the air interface. The proposed system has lower transmission losses and greater power efficiency than current state-of-the-art implementations. Other advantages include fast antenna main beam steering, reduced antenna weight, and reduced susceptibility to RF interference on the feeder network. Results are presented showing measured radiation patterns for a prototype fibre-to-air antenna and those of an electronically controllable optical phase shifter.
