Today, renewable energy source of power generation has become very promising. As we know that conventional or non-renewable source of energies are very limited and are depleting very rapidly. Increasing energy needs of the world and continually growing population there is a power demand gap and it needs alternate sources of energy. So, there is a view to generate more and more power from renewa...

abstract the aim of this survey is to compare utilization systems (cooperative, private and governmental) methods of energy consumption in soybean production and the evaluation of energy inputs effect in yield of soybean in moghan. for this purpose, the information were collected from 54 private farmers, 14 cooperative members farmers and 14 agro-industry units by questionnaire method. the maxi...

Transformation of the energy sector to efficiency and climate protection The increasing demand for energy services in conjunction with extensive climate protection targets requires significant changes within the European energy sector. Consequently, a continuous transition from conventional and fossil fuelled power generation to low-carbon or even carbonfree generation is expected in the power ...

Nowadays the position of the renewable energy is so important because of the environment pollution and the limitation of fossil fuels in the world. Energy can be generated more and more by the renewable sources, but the fossil fuels are non-renewable. One of the most important renewable sources is the wind energy. The wind energy is an appropriate alternative source of fossil fuel. The replacem...

This paper analyses the impact on renewable energy sources integrated into the Romanian power system on the electrical network operation considering the reduction of electricity consumption with respect to the 1990s. This decrease has led to increased difficulties in integrating the renewable energy sources into the power system (network reinforcements), as well as issues concerning the balance...

The amount of generation of renewable energy sources in the European grid has strongly increased. In 2005 eight times more energy was generated by RES compared to 1990. In the future the EU wants to promote the integration of RES. Mainly the use of wind energy and biomass should be expanded. As to date, RES were connected to the distribution grid usually with a ”fit and forget” approach. Due to...

Renewable Energy Sources (RES) are nowadays growing rapidly at the distribution level and it employs power electronic converters to ensure reliable operation to the customers. Among the RES, wind energy is now firmly established technology for electricity generation. This paper proposes a conventional PI controller and Artificial Neural Network (ANN) controller to GSC of PMSG, which can obtain ...
