MAXIMUM ACTIVE POWER TRANSMISSION EFFICIENCY AND POWER FACTOR DEFINITION IN HYBRID SYSTEMS WITH ARBITRARY WAVEFORMS

open access: yesLatin American Applied Research - An international journal, 2023
Based on a theorem giving the maximum available active power with constant transmission losses valid for arbitrary waveforms it is possible rigorously generalize the definitions of power factor based on the definition of apparent power as the maximum power available. Then it could be applied to systems with non-symmetric, non-sinusoidal, and eventually

Allocating Transmission to Mitigate Market Power in Electricity Networks [PDF]

open access: yes
We ask what conditions transmission contracts increase or mitigate market power. We show that the allocation process of transmission rights is crucial. In an efficient arbitraged uniform price auction, generators will only obtain contracts that mitigate ...
