Protection Strategies for the Connection of Diode Rectifier-Based Wind Power Plants to HVdc Interconnectors
(Institute of Electrical and Electronics Engineers, 2020-10-05)
The connection of diode rectifier (DR)-based wind power plants (WPPs) to existing or planned high-voltage dc (HVdc) interconnectors can lead to important savings on cost and system robustness. Since the DR station usually ...
Multivariable phase-locked loop free strategy for power control of grid-connected voltage source converters
(Elsevier, 2022-05-17)
A multivariable control strategy in a reference frame for grid-connected voltage source converters (VSCs) without using a phase-locked loop (PLL) is presented in this paper. First, common VSC controls such as vector current ...
Deep learning-based forecasting of aggregated CSP production
(Elsevier, 2020-02-25)
This paper introduces deep learning-based forecasting models for the continuous prediction of the aggregated production generated by CSP plants in Spain. These models use as inputs the expected top of atmosphere ...
Evaluation of Storage Energy Requirements for Constant Production in PV Power Plants
(Institute of Electrical and Electronics Engineers (IEEE), 2013-03)
This paper analyzes the minimum energy capacity ratings that an energy-storage (ES) system should accomplish in order to achieve a defined constant power production in a photovoltaic (PV) power plant. ES is a key issue for ...
