Reactive power control of wind-diesel-micro-hydro hybrid power systems using matlab/simulink
This paper presents reactive power control of isolated wind-diesel-micro-hydro hybrid power system for realistic load disturbance using matlab/simulink. The mathematical model of the system based on matlab/simulink is developed. Reactive power control performance is compared using three different types of Static VAR Compensators (SVC). Transient responses for step plus normally distributed or ...

Rural electrification through renewable energy in Nepal
Nepal is rich in hydropower. However, due to various constraints the rural sector of Nepal is still deprived of a national electrical grid. Renewable energy resources are the most viable and accessible sources to electrify these rural sectors. Micro-hydro and solar photovoltaics (PV) are widely used renewable energies for rural electrification. Presently, this source provides electricity to only ...

The history of Hydrobox
It all started with a late night beer in a hotel bar in Accra, when Thomas Poelmans & Christian Verbrugghe met while participating in the 2015 trade mission to Ghana organised by Flanders Investment & Trade. Thomas was working under Green Crossroads as an independent consultant & project developer in search of a new venture. Christian was a director in Malthe Winje, a Norwegian ...

The Sol of Cuba
I went to Cuba with Global Exchange, a non-profit organization that organizes “reality tours” of Cuba. The tour coincided with an international solar energy conference organized by CubaSolar, a nongovernmental Cuban organization. Having worked on numerous solar energy projects in Central America, I went to Cuba with the misconception that I could use my renewable energy technology transfer skills ...

The potential impacts of climate change on hydropower generation in Mid Wales
Hydropower is a potential large source of electricity supply in Wales. The Upper River Severn in Mid Wales is a typical stream where a high head hydropower scheme could be developed and the river system at Plynlimon has some of the longest records for weather and flow in Wales. A micro-hydropower potential of 99 kW is demonstrated at Plynlimon and the potential impacts of climate change are ...

Energy recovery potential using micro hydropower in water supply networks in the UK and Ireland
The supply and treatment of water is a highly energy intensive process, resulting in large amounts of greenhouse gas emissions as well as incurring large economic costs. Both governments and water service providers worldwide recognise the need for more sustainable water supply systems. In recent years, the use of hydropower turbines within water supply networks has been shown as a viable option ...

A small island in the Indian Ocean offers big lessons on clean power
The Indonesian island Sumba is working to provide 100% renewable electricity to all 650,000 residents by 2025. As the sun sets on the small Indonesian island of Sumba, Danga Beru Haba begins weaving under the glow of a single incandescent lightbulb, the only one in her home. Although she is tired from working dawn to dusk in the fields surrounding her village of Kampung Kalihi, the sarong she is ...

Power conditioning of an uncontrolled micro-hydroturbine-driven induction generator for distributed generation using a battery energy storage system
Distributed Generation (DG) and its interconnection to the AC power grid is a relatively new concept. DG employs small generators, which are distributed throughout the power system. The electricity is usually generated by renewable energy sources such as wind, hydro and tidal, which are intermittent in nature. These generators connected to the AC grid may lead to severe power quality problems. ...
