Power losses from wind generated electricity in high voltage AC transmission: an analysis through simulation
In this paper, we have investigated different types of losses from wind generated electricity in high voltage AC (HVAC) transmission. Wind power generation is expensive in nature and it is thus necessary to know how much power is lost in the transmission. We have simulated an HVAC transmission system with a wind power generator in Simulink. We varied different components of the system namely wind ...

The power coefficient of windmills in ideal conditions
The windmill efficiency, also designated as the power coefficient, is defined as the ratio of the actual power output to the power present in the free stream of a fluid flowing through the same cross-sectional area. There are remarks in the literature to the effect that the power coefficient of actual windmills is very close to the ideal power coefficient or Betz limit of 0.5926. In this paper, ...

Intermittency of wind: the wider picture
This paper puts the discussion on intermittency of wind into its wider context: in the first part, it reviews the natural variability of all resources that power renewable energy technologies. This highlights how intermittency of wind influences the degree of variability relative to other renewable energy technologies, but does not change its kind. In the second part, management options for ...

Sustainable nuclear energy: some reasons for optimism
This paper traces various aspects of nuclear electrical power from about 1970 when it burst on the world scene, starting in the USA and spreading rapidly to the rest of the world. Taking the US situation as typical, and perhaps dominant, I show that the cost of nuclear electricity was cheap in 1973, and the developments since then mostly related to public perception, that made it more expensive. ...

Interregional power transmission: a component in planning for renewable energy technologies
We discuss the role played by interregional power transmission on the basis of recent scenario work. In a project dealing with long-term planning for energy efficiency and renewable energy in Europe [described thoroughly in 1-4], we modelled a scenario for the present 15 EU countries' energy system in 2050. The basis for the scenario is the concept of "fair pricing" for energy services, meaning ...

Performance evaluation of solar tunnel dryer for grape drying
This paper presents the performance of solar tunnel dryer to dry chemically untreated grape. Average air temperature rise in dryer was in the range of 20-21?C above the ambient temperature and it was almost constant in the dryer. The solar tunnel dryer of size 10 ? 3.75 m² is in position to dry 320 kg of grapes from 85% (wb) moisture content to 16% (wb) moisture content within seven days. ...

Cascade failures and distributed generation in power grids
Power grids are nowadays experiencing a transformation due to the introduction of distributed generation based on renewable sources. At difference with classical distributed generation, where local power sources mitigate anomalous user consumption peaks, renewable sources introduce in the grid intrinsically erratic power inputs. By introducing a simple schematic (but realistic) model for power ...

Prospects for nuclear energy in South Asia in the 21st century
The South Asian region is characterised by low per capita energy consumption. There are large differences in the region with regard to energy resource endowments. In the entire region one notices an excessive use of non-commercial energy. The region has significant hydro-potential, which needs to be fully exploited. There are possibilities for trade in energy in the region. India is the largest ...
