The impact of reactive power generation in PV systems on their yearly production of electrical energy

RE&PQJ
The paper deals with photovoltaic (PV) systems able to generate reactive power and to curtail active power generation. Based on measurements performed on an existing PV system over 10 years its typical yearly operation profile is determined. It is used to evaluate the ability of the PV system to generate reactive power.

Production of electrical power through hydraulic energy and its environmental impacts

, 2013
http://dx.doi.org/10.5902/223611709124Este trabalho teve por objetivo fazer uma revisão bibliográfica de como a energia elétrica é gerada a partir das usinas hidrelétricas e os impactos ambientais trazidos por esse tipo de empreendimento. A energia hidráulica é produzida através da força do movimento das águas, por meio das usinas hidrelétricas.

Design of an Electrical Power Take-Off for a Wave Energy Converter for Hydrogen Production

Energies
In this work, the design of a linear electric generator and an electronic power converter to be integrated into a system to produce hydrogen by exploiting sea waves’ motion is described. The results of Finite Element Method (FEM) simulations for the design of the linear induction generator are presented and discussed along with relevant considerations ...

Wind energy potential and the possibilities of the use of wind energy in the production of electric power in our country

, 2003
Today the energy of wind participates in the overall global production of electric power with only 0.4 %. However, according to the presently existing world trends, it can be predicted that in the following decades this low percentage might become thirty times larger.

Geothermal Energy Utilization of Co-Production Water from Oilfields for Electric Power Generation

Solar Energy and Sustainable Development Journal
One significant source of geothermal energy is the co-produced hot water from oil/gas field production. There is potential to utilize oilfield infrastructure to produce geothermal electricity profitably, in a process called co-production. Due to the increasing demands of energy now days, this paper presents an investigation of geothermal energy ...
