Model selection and mechanism design for electricity markets in hydropower‐rich regions: Adaptation study

open access: yesIET Generation, Transmission &Distribution, Volume 17, Issue 14, Page 3286-3301, July 2023., 2023
Most of the first eight pilot regions in China have entered the long‐period continuous operation stage, and the second batch of six power spot pilots have started their simulation trial runs; however, the construction of power markets in the hydropower‐rich regions of China (i.e.

Eco‐evolutionary factors that influence its demographic oscillations in Prochilodus costatus (Actinopterygii: Characiformes) populations evidenced through a genetic spatial–temporal evaluation

open access: yesEvolutionary Applications, Volume 16, Issue 4, Page 895-910, April 2023., 2023
Abstract The human activity impact on wild animal populations is indicated by eco‐evolutionary and demographic processes, along with their survival and capacity to evolve; consequently, such data can contribute toward enhancing genetic‐based conservation programs.

The future of suitable habitats of an endangered Neotropical grassland bird: A path to extinction?

open access: yesEcology and Evolution, Volume 13, Issue 2, February 2023., 2023
The Campo Miner is a grassland bird of the Brazilian Cerrado and threatened with extinction that has been suffering from the reduction of habitat. Here, we use ecological niche models to understand the environmental suitability of the species in the present and in the future.

An application of four‐wire grid‐forming power inverter in unbalanced distribution network

open access: yesIET Generation, Transmission &Distribution, Volume 17, Issue 2, Page 324-336, January 2023., 2023
Abstract The modelling of a three‐phase four‐leg four‐wire grid‐forming inverter in a low voltage distribution system 18‐bus European Cigré under unbalanced conditions in an autonomous distribution network is presented. The case study has two types of inverters control strategy: (i) grid‐forming to supply all the system demand in the interval of the ...

Which traits optimize plant benefits? Meta‐analysis on the effect of partner traits on the outcome of an ant–plant protective mutualism

open access: yesJournal of Ecology, Volume 111, Issue 1, Page 263-275, January 2023., 2023
Our results highlight that the selective pressures and evolutionary routes in ant‐plant protective mutualisms may depend on the pool of traits exhibited by partner species. Although some studies have already reported some impact of species traits on the outcome of ant‐plant mutualisms, this is the first time that a generalization about the role of ...

A DFT‐based method for estimating interharmonics in wind power generation

open access: yesIET Smart Grid, Volume 5, Issue 5, Page 332-346, October 2022., 2022
Abstract This paper introduces a discrete Fourier transform (DFT)‐based method for estimating the amplitudes and frequencies of interharmonics, which arise from the interaction between wind power generators and electric power systems. This method exploits the synergy of choosing signal enhancement, mains frequency estimation, and re‐sampling techniques.

Value of human‐modified forests for the conservation of canopy epiphytes

open access: yesBiotropica, Volume 54, Issue 4, Page 958-968, July 2022., 2022
Although HMFs provide important refuge for many species, our results show that they do not provide suitable conditions for the maintenance of current or future canopy epiphyte communities. Our findings suggest that conserving large continuous old‐growth forests is the only viable conservation option for protecting most vascular epiphytes.
