The use of sensor networks has increased rapidly over the last years. Due to their low resources, sensors come along with new issues regarding network security and energy consumption. Focusing on the network availability, previous studies proposed to protect the network against denial of service attacks with the use of traffic monitoring agents on some nodes. But if the control nodes go down or get...

In this paper, a new control strategy is proposed for hybrid energy storage system (HESS) for remote area power supply system consisting of PV, battery, supercapacitor (SC) and load. Since the PV generation and load demand varies continuously, batteries can undergo irregular, partial charge/discharge cycles. It has detrimental effects on battery life span and rating. Therefore in the proposed method,...
Because AC module system is directly connected to grid source, power pulsation is appeared at AC module input capacitor. So, it can adversely affect maximum power point tracking (MPPT) control. Furthermore, photovoltaic (PV) module power can be fluctuated with varying irradiation while constant load demand. To reduce power fluctuation for MPPT control and stabilize the PV system with varying conditions,...
As the distribution grid increasingly integrate rooftop solar PV, their power generation outputs are uncertain due to the solar radiation, panel temperature, passing cloud, and v-i characteristic operating level. Therefore, PV grid connected system would require a supplementary source to ensure more stable PV power generation, particularly during cloudy periods. In this paper, the battery storage...
This paper presents an efficient MPPT controller. Incremental conductance algorithm is chosen for MPPT to improve the efficiency. The advantage of this algorithm is that the operating point does not oscillate around the Maximum Power Point. The algorithm also detects the atmospheric conditions. The operating point gets shifted according to the irradiance. The DC-DC converter chosen is a MOSFET based...
In this paper a battery model for life-preserving conditions is developed. For the identified adverse effects, a battery operation range is defined. The operation range is wide enough to obtain good performance of the battery but it also prevents battery malfunctioning and the need of battery replacement decreases. With a close-up operation range, a new mathematical battery model with both accuracy...
Increasing demands of eco-friendly vehicles, various types of hybrid electric vehicle (HEV) have been researched and released.

This paper shows the results of a development project that aims to provide Electric Vehicle (EV) drivers the opportunity to know, before making a trip, how the battery will progress during the route. This means drivers will know if they have to stop to recharge the battery and where they should do it, ruling out the idea that makes people reject buying an EV because they can't make long trips for...
