Unit Commitment in Presence of Wind Power Plants and Energy Storage

As renewable energy increasingly penetrates into power grid systems, new challenges arise for system operators to keep the systems reliable under uncertain circumstances, while ensuring high utilization of renewable energy. This paper presents unit commitment (UC) which takes into account the volatility of wind power generation. The UC problem is solved with the forecasted intermittent wind pow...

Preparatory power posing affects nonverbal presence and job interview performance.

The authors tested whether engaging in expansive (vs. contractive) "power poses" before a stressful job interview--preparatory power posing--would enhance performance during the interview. Participants adopted high-power (i.e., expansive, open) poses or low-power (i.e., contractive, closed) poses, and then prepared and delivered a speech to 2 evaluators as part of a mock job interview. All inte...

Optimal Coordinated Voltage Control in Distribution Networks in presence of Solar and Wind Power Plants Considering Uncertainties

Abstract: In the last decade, the amount of distributed generation connected to the distribution network is increasing. The presence of distributed generation resources in distribution systems has a great influence on its behavior and it is necessary to consider the impact of these resources on the distribution network design. In this study, Optimal Coordinated Voltage Control (OCVC) using wind...
