Wind Energy Usage for Building Heating Applying Hydraulic System

Hydraulic Motor Driving Variable-Pitch System for Wind Turbine

The present hydraulic variable-pitch mechanism of wind turbine uses three hydraulic cylinders to drive three crank and connecting rod mechanisms respectively; the blades are moved with the cranks. The hydraulic variable-pitch mechanism has complex structure, occupies a lot of space and its maintenance is trouble. In order to make up for the shortcomings of hydraulic cylinder variable-pitch syst...

Integrated Power Management System for Zero-energy building: Techno-Economic Analysis

A complete understanding of the limits, barriers, and equipment available for the use of national energy resources is essential. This will increase the use of existing regional energy potential and pave the way for sustainable development. In this study, the Green Cottage power management system from a renewable energy source was designed and evaluated using a decision-making algorithm. Thirtee...

Electrical Energy Storage System for Wind Turbines

Energy storage devices and solutions are required for power quality and balance within wind systems. In the context of rapidly expanding of distributed energy sources, the wind energy converters are in the center of interest. In this case, the direct dependence of the power generation capability for a given wind speed represents a major problem of wind energy conversion with regard to large-sca...

Study on an Existing PV/Wind Hybrid System Using Biomass Gasifier for Energy Generation

Untapped pine needles with high potential for energy generation in the hilly area are not only a waste of resource but also increase the chance of environmental hazards as forest fires and GHG emission. This study is conducted to propose a new hybrid system (PV/Wind/Biomass) using abundant pine needle resource as a replacement of existing roof-mounted PV/wind hybrid system and analyse the feasi...
