How does intermittent wind power interact with controllable power?

Author:  Deroover, Marc

This article considers a typical load supplied by a set of identical controllable units. More and more wind power is then added to the production system, and the simulation shows how the system behaves and how the wind power is used. The analysis considers only the energy and power balances at system level, using the Load Duration Curve representation of the load. No consideration is given to the network constraints, power prices and other similar topics. It is basically a . . .

Researchers Have Been Underestimating the Cost of Wind and Solar

Author:  Tverberg, Gail

A big part of our problem is that we are dealing with variables that are “not independent.” If we add subsidized wind and solar, that act, by itself, changes the needed pricing for all of the other types of electricity. The price per kWh of supporting types of electricity needs to rise, because their energy returns on energy invested fall as they are used in a less efficient manner. This same problem affects all of the other pricing approaches as well, including levelized cost of energy. Thus, our current pricing approaches make intermittent wind and solar look much more beneficial than they really are.

Windenergie in Deutschland und Europa

Author:  Linnemann, Thomas; and Vallana, Guido

Windenergie in Deutschland und Europa [Wind energy in Germany and Europe: Status quo, potentials, and challenges in the baseload supply of electricity – Part 1: Developments in Germany since 2010] English Abstract: In Germany, the installed nominal capacity of all wind turbines has increased eightfold over the past 16 years to 50,000 megawatts today. In the 18 most important European countries using wind energy today, the nominal capacity rose twelvefold to more than 150,000 megawatts. One essential physical property of wind . . .

Evaluation of a proposal for reliable low-cost grid power with 100% wind, water, and solar

Author:  Clack, Christopher; Qvist, Staffan; Apt, Jay; et al.

[Abstract] A number of analyses, meta-analyses, and assessments, including those performed by the Intergovernmental Panel on Climate Change, the National Oceanic and Atmospheric Administration, the National Renewable Energy Laboratory, and the International Energy Agency, have concluded that deployment of a diverse portfolio of clean energy technologies makes a transition to a low-carbon-emission energy system both more feasible and less costly than other pathways. In contrast, Jacobson et al. [Proc Natl Acad Sci U S A 2015;112(49):15060–5 (ref. 11)] argue that it is . . .
