At present scenario, renewable energy sources are needed to meet the energy demand. They also mitigate environment pollution problems. The shortage of electrical energy demand can be meeting with renewable energy resources. A wind turbine (WT) and photovoltaic (PV) solar panels are primary energy sources. Grid connected renewable energy source like wind energy and solar energy are used to conne...

A sustainable residential microgrid composed of two distributed generation sources (photovoltaic panels and biofuel generator), one energy storage device (battery bank), and able of supplying both AC and DC loads, including a plug-in hybrid electric vehicle, is proposed. The microgrid can operate in grid-connected mode and island mode. It is composed of a main DC bus and also an AC bus. The cha...

In today's electric power systems, power electronic converters play an increasingly important role for integration of smart grids, renewable energy resources and energy storage devices. Power converters are key components that physically connect wind power, solar panels, and batteries to the grid. Traditionally, those converters are controlled using standard control mechanisms. However, recent ...

A significant challenge in energy system cyber security is the current inability to detect cyber-physical attacks targeting and originating from distributed grid-edge devices such as photovoltaics (PV) panels, smart flexible loads, and electric vehicles. Cyber grid defenders lack the necessary algorithms and other detection capabilities to distinguish between normal operations, cyber-attacks, a...

The paper presents common mode voltage analysis of single phase grid connected photovoltaic inverter. Many researchers proposed different grid tie inverters for applications like domestic powering, street lighting, water pumping, cooling and heating applications. Traditional grid tie PV inverter uses either a line frequency or a high frequency transformer between the inverter and grid. The tran...

This paper determines and compares the cost of energy (COE) of various hybrid systems for several off-grid facilities in North and Far North regions of Cameroon by integrating renewable sources and/or storage with diesel generators. The estimated annual energy production by solar PV systems and wind turbines is also discussed. The aim is to study the application of a high penetration renewable ...

The rapid rise in the number of fossil fuel uses over last few decades has increased carbon dioxide (CO2) emissions. purpose implementing renewable energy solutions, such as solar, hydro, wind, biomass, and other sources, is to mitigate global climate change worldwide. Solar received more attention an alternative source energy, it can play essential role future industry. This especially true so...

As the costs of manufacturing photovoltaic (PV) panels continue to decrease, the use of PV-based solar energy systems is seen in rise across the globe. This paper proposes an asymmetrical DC-DC converter for standalone solar energy systems. The converter is developed to control modularized PV panels with a combination of soft-switching, flyback-forward, high-step-up voltage ratio, and fault tol...

This paper presents our eeorts to accurately track a Head-Mounted Display (HMD) in a large environment. We review our current benchtop prototype (introduced in WCF90]), then describe our plans for building the full-scale system. Both systems use an inside-out optical tracking scheme, where lateral-eeect photodiodes mounted on the user's helmet view ashing infrared beacons placed in the environm...
