The entire wind farm is regarded as a large-capacity wind turbine for modeling double-fed wind farm. The influence of flow field characteristics in the wind farm has been ignored. In order to reflect the influence in double-fed wind farm equivalent modeli... see more

This paper aims to explore a viable solution for a doubly-fed induction generator (DFIG)-based wind farm to meet the reactive support requirement of the low voltage ride-through (LVRT) grid code with safe grid-connected operation during asymmetrical grid ... see more

In the context of the rapid development of renewable energy in Germany in the last decade, and increased concerns regarding its potential impacts on farmland prices, this paper investigates the impact of wind energy and biogas production on agricultural l... see more

The increasing share of offshore wind energy traded at the spot market requires short term wind direction forecasts to determine wake losses and increased power fluctuations due to multiple wakes in certain wind directions. The information on potential po... see more

A novel control strategy is proposed in this paper for the rotor side converter (RSC) of doubly-fed induction generator (DFIG)-based wind power generation systems. It is supposed to enhance the low-voltage ride-through (LVRT) capability of DFIGs during gr... see more

Uno de los generadores eólicos más utilizados es el generador de inducción doblemente alimentado (DFIG, por sus siglas en inglés.). Este tipo de generador tiene la capacidad de seguir generando cuando es desconectado de la red eléctrica principal. Esto pe... see more

Sorghum is important for sustainability of smallholder farmers’ subsistence, social and economic livelihoods in semi-arid and arid environments of Southern Africa. However, production of the crop has been on the decline in the smallholder communities of s... see more

While Tanzania has been facing food shortage for some decades, little efforts have been made to elicit optimal crop yields. To limit this problem, there is a need for a robust agricultural policy that aims at stabilizing agricultural production and socio-... see more
