Coordinated Control Strategies of VSC-HVDC-Based Wind Power Systems for Low Voltage Ride Through
Energies, 2015 The Voltage Source Converter-HVDC (VSC-HVDC) system applied to wind power generation can solve large scale wind farm grid-connection and long distance transmission problems. However, the low voltage ride through (LVRT) of the VSC-HVDC connected wind farm

Farmflow : extensively validated and dedicated model for wind farm control
, 2020 In a wind farm, turbines affect each other through their wakes, decreasing their power production and increasing the structural loading (wear and tear) of their components.

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.

Control of a wind farm with an internal direct current collection grid
, 2011 For a high-voltage, direct current connected wind farm, an internal direct current (DC) collection grid is a possible further development that can reduce the weight of the transformers significantly, with average losses for the DC system of 3%.

Climate change and perennial crop production: Evidence of yield impact and adaptation in California
American Journal of Agricultural Economics, EarlyView.Abstract Perennial crops are economically important. They contribute to food security, providing essential nutrients that are often lacking in annual crops, and provide additional environmental benefits compared with annual crops. Despite their importance, empirical research on the impacts of climate change and adaptation on perennial crops remains ...

American Journal of Agricultural Economics, EarlyView.Abstract This paper derives a firm‐level threshold, the Herfindahl Neutral Point, from the standard concentration index used in merger review. At this threshold, a marginal expansion leaves the index unchanged. Firms below the threshold reduce concentration when they expand; firms above it increase concentration.

Optimization Method of Multi-Mode Model Predictive Control for Wind Farm Reactive Power
EnergiesThis paper presents a novel approach for optimizing wind farm control through the utilization of a combined model predictive control method. In contrast to conventional methods of controlling active and reactive power in wind farms, the suggested ...
