Journal ArticleDOI
Coordinated Active Power Curtailment of Grid Connected PV Inverters for Overvoltage Prevention
TL;DR: In this paper, the authors discuss the use of droop-based active power curtailment techniques for overvoltage prevention in radial LV feeders as a means for increasing the installed PV capacity and energy yield.
Journal ArticleDOI
Performance assessment of active frequency drifting islanding detection methods
Luiz A. C. Lopes,Huili Sun +1 more
TL;DR: In this article, a load parameter space based on the values of the quality factor and resonant frequency of the local load (Q/sub f/ versus f/sub 0/) was used to represent the NDZ of frequency drifting IDMs for any RLC loads.
Journal ArticleDOI
Self-Tuning Virtual Synchronous Machine: A Control Strategy for Energy Storage Systems to Support Dynamic Frequency Control
TL;DR: In this paper, a virtual synchronous machine (VSM) is used to support dynamic frequency control in a diesel-hybrid autonomous power system, where self-tuning algorithms are used to continuously search for optimal parameters during the operation of the VSM in order to minimize the amplitude and rate of change of the frequency variations and the power flow through the ESS.
Proceedings ArticleDOI
An improved perturbation and observation maximum power point tracking algorithm for PV arrays
Xuejun Liu,Luiz A. C. Lopes +1 more
TL;DR: In this article, a new implementation of a perturbation and observation (P&O) maximum power point tracking (MPPT) algorithm that can mitigate/reduce the main drawbacks commonly related to the P&O method is discussed.
Journal ArticleDOI
Vector Control of Single-Phase Voltage-Source Converters Based on Fictive-Axis Emulation
TL;DR: In this paper, the authors proposed an alternative way for the current regulation of single-phase voltage-source dc-ac converters in direct-quadrature (dq) synchronous reference frames.
