An Overview of Active Power Control in Wind Farms

发电技术, 2018
Due to the randomness, volatility and anti peak characteristics of wind power, a high proportion of wind power penetrating into the power grid will have a great impact on the stability and security of the power system.

Improved nonlinear mapping network for wind power forecasting in renewable energy power system dispatch

Energy Reports, 2022
Wind power forecast (WPF) plays vital role in renewable energy power system dispatch. Inaccurate WPF caused by the stochastics and fluctuation of wind energy would lead to frequently modify power system dispatch scheduling and even endanger power system ...

Analysis of curtailment at The Geysers geothermal Field, California [PDF]

, 2020
Geothermal energy has traditionally been viewed as a baseload energy source, but the rapid growth of intermittent renewable energy has led to a need for more flexibility in power generation to avoid mandatory curtailment imposed by grid operators.

Opportunities for Price Manipulation by Aggregators in Electricity Markets [PDF]

, 2016
Aggregators are playing an increasingly crucial role in the integration of renewable generation in power systems. However, the intermittent nature of renewable generation makes market interactions of aggregators difficult to monitor and regulate, raising

Hierarchical Optimization Strategy Considering Regulation of Electric-Fused Magnesium High-Energy-Consuming Load and Deep Peak Regulation of Thermal Power

Energies
The randomness and volatility of wind power increase peak regulation pressure, leading to wind curtailment despite the deep peak regulation efforts of thermal power units.

Wind and Solar Curtailment: International Experience and Practices [PDF]

, 2013
High penetrations of wind and solar generation on power systems are resulting in increasing curtailment. Wind and solar integration studies predict increased curtailment as penetration levels grow. This paper examines experiences with curtailment on bulk

Dammarenediol II enhances etoposide‐induced apoptosis by targeting O‐GlcNAc transferase and Akt/GSK3β/mTOR signaling in liver cancer

Molecular Oncology, EarlyView.
Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...
