Do More Open Economies Export Less Diversely in Brazilian Agribusiness?

open access: yesAgribusiness, EarlyView.
ABSTRACT This paper asks whether municipalities with a larger export‐to‐revenue ratio display a more concentrated bundle of exported goods in Brazilian agribusiness. Recent advances in export imputation for Brazilian municipalities allow for an analysis of the concentration profile of each municipality and its association with export openness.

Optimization of an active control strategy for wind farm clusters considering their integration performance difference

open access: yesZhejiang dianli
To more reasonably and accurately control the output of new energy in large-scale wind farm clusters in the scenario of multiple nested cross sections, an optimization strategy for active control of wind farm clusters considering differences in their ...

How Does Patient Capital Enhance Agribusiness Resilience? Evidence From Chinese Listed Agribusinesses

open access: yesAgribusiness, EarlyView.
ABSTRACT In emerging economies where smallholder farming dominates agricultural production, agribusinesses serve as critical intermediaries linking smallholders to broader markets, and their resilience directly affects agricultural sustainability. Short‐term‐oriented capital is reluctant to adequately finance highly uncertain and cyclical agricultural ...

2.5a_Pedersen: The influence of wind farm control on optimal wind farm layout

open access: yes, 2019
Design of an optimal wind farm topology is dependent on the chosen wind farm control strategy. The objective of this paper is to investigate the influence of optimal wind farm control on the optimal wind farm layout as seen from a production perspective.

Active Power Control of Waked Wind Farms

open access: yesIFAC-PapersOnLine, 2017
Active power control can be used to balance the total power generated by wind farms with the power consumed on the electricity grid. With the increasing penetration levels of wind energy, there is an increasing need for this ancillary service. In this paper, we show that the tracking of a certain power reference signal provided by the transmission ...

Uncovering renewable energy policy impact channels on land values, the local farm structure, and farmland heterogeneity

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...

Analysis of small signal stability in direct-drive wind farm under wind power generation variations

open access: yes电力工程技术
The small-signal stability problem of large-scale grid-connected wind farms consisting of permanent magnet synchronous generators (PMSGs) under wind power variations is addressed in this paper, with focus placed on the DC-link voltage timescale.

Lost ground, lost value: Investigating the relationship between soil erosion and agricultural land value

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract This study examines the impact of soil erosion on agricultural land values in the United States (US) Midwest. Based on a novel county‐level panel data set with information on soil erosion levels and agricultural land values covering five census years (1997, 2002, 2007, 2012, and 2017), we separately investigate the direct effect of two types ...
