As a reaction to environmental footprint, high cost and long payback period of building renewable energy power plants, governments started to scale down renewable energy to the commercial and residential building entities. In this article, the feasibility of residential solar, wind, and hybrid solar-wind power generators to meet electricity demand to a typical villa in Abu Dhabi is analyzed. The evaluation...
The objective of this paper is to control the frequency of hybrid renewable energy system (HRES) with the help of proportional-integral (PI) controller according to sudden change in wind speed, load demand and solar radiation. A comparison study is presented in this paper between conventional PI controllers and PSO tuned optimal PI controllers. The HRES is combination of multiple generation and storage...
In wind power plants typically squirrel-cage induction generators (SCIG) tend to drain large amount of reactive power from the grid, potentially causing a drop voltage. To improve SCIG’s power quality and transient stability, this paper investigates a new pitch angle control strategy, including normal scheme and Fault-Ride-Through (FRT) scheme, based on hybrid of PI and Fuzzy logic technique. In particular,...
Wind - Photovoltaic Hybrid System utilization is becoming popular day by day given to its reliable energy resources, decreasing prices of turbines and PV panels and increase in overall energy cost and reduced emission.

Electricity is the base of development of a country and the need of electricity is increasing every moment. Developing countries like Bangladesh are facing severe energy crisis. Most of the power generation in Bangladesh is based on natural gas and fossil fuel which makes it hard to meet the increasing demand. As a tropical country, Bangladesh is blessed with renewable energy resources all over the...
This paper is devoted to study the conversion of renewable energy resources into electrical energy in a standalone hybrid power generation system.

A hybrid energy system is an excellent solution to the problem of not being able to meet the power demand using a single energy source. Such a system incorporates a combination of one or more renewable energy source (RES) such as solar photovoltaic, wind-energy, geothermal, and could also have a conventional generator for backup. This paper discusses different system components of a hybrid energy...
In this paper, the data acquisition system is developed to monitor the wind speed, solar irradiation, and PV temperature based on a low-cost AVR microcontroller.
