Behaviour of grid connected photovoltaic systems

The grid connected photovoltaic is one of the expected local power supply system that consists of distributed generators, loads, power storage devices, heat recovery and power electronics equipments. In this paper, a grid connected Photovoltaic (PV) energy system is presented to investigate the performance of the microgrid. The proposed model has been developed in Matlab-Simulink environment based on an improved control methodology incorporated within the Photovoltaic Generation System (PVGS). Finally, simulation results show the high performance of the proposed method and the recovered power is achieved

Intelligent Image Capturing Alarm System Using Raspberry Pi

Home surveillance system assumes an essential part in this present day living style to help recognizing illegal activities. In this proposed paper, an intelligent image capturing alarm system to protect locker was developed. Raspberry Pi 2 is used as the main controller (server). At the point when any conceivable intrusion is identified, a webcam installed to Raspberry Pi 2 will capture the picture of the intruder. In the meantime, the spotlight or light of the house which represented by an LED will be turned "ON" alongside an alarm sound from a buzzer which is fixed as an output. Taking everything into account, this improvement offers reasonable and easy to use surveillance alarm system

The Smart Grid Experience in Europe

The development of a Smart Grid in Europe has a strong link to the climate goals for sustainable energy systems. Europe has been at the forefront of smart grid deployments, especially in the areas of managing large penetrations of renewable sources of energy, advanced metering infrastructure (AMI) and on advanced information technology. The article is Part of the IEEE Smart Grid Newsletter - August 2014QC 20140828</p
