Compensation of forecast error in large PV plants with battery storage: associated strategies
(2017)
info:eu-repo/semantics/conferenceObject,
As penetration rates of utility-scale photovoltaics (PV) increases, large PV plants will participate in the daily wholesale electricity market in the same way that wind farms. Then, PV plant owner can receive some kind of ...
Tools for the high penetration of PV systems in the EU electrical networks: results of PVCROPS Project
(EU PVSEC, 2015)
Contribución a congreso / Biltzarrerako ekarpena,
The Solar Energy Industrial Initiative established the objective of integrating PV into the grid to provide up to 12% of the EU electricity demand. The FP7 project PVCROPS has developed solutions to allow the high penetration ...
On the stability criteria for inverter current control loops with LCL output filters and varying grid impedance
(IEEE, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
The use of LC and LCL filters and grid impedance variations are creating new challenges on the controller design for current control loops of photovoltaic and wind turbine inverters. In the design process, stability criteria ...
Comparison of linear and and small-signal models for inverter-based microgrids
(IEEE, 2014)
Contribución a congreso / Biltzarrerako ekarpena,
Frequency and voltage regulation in droop-based microgrids is generally modeled using small-signal analysis. In order to ensure accuracy, existing models do not decouple real and reactive power responses. However, the ...
DC capacitance reduction in three-phase photovoltaic inverters by using virtual impedance emulation
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
DC voltage regulation in grid-connected three-phase PV inverters is a fundamental requirement. In order to reduce the influence of the PV non-linear behavior and ensure stability in the whole operating range, the input ...
Single feedback regulation of the AC voltage for high-power inverters under stand-alone operation
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
Energy-storage inverters under stand-alone operation must control the output voltage. However, existing methods for instantaneous voltage regulation are not suitable for high-power inverters due to their limited sampling ...
Economic analysis of residential PV self-consumption systems with Li-ion batteries under different billing scenarios
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
In this paper, an economic analysis for four houses with a PV self-consumption system with and without Li-ion batteries is carried out. In particular three different ways of sizing PV and batteries are analyzed under three ...
On the calculation of the STC power of PV generators by using typical monitoring system data
(2017)
info:eu-repo/semantics/conferenceObject,
The properly in-field characterization of the power at Standard Test Conditions, PSTC, of PV generators is becoming increasingly important in order to evaluate their performance and its evolution in time. Within the state ...
Ramp-rate control in large PV plants: battery vs. short-term forecast
(2018)
info:eu-repo/semantics/conferenceObject,
The changeability in the power produced by utility-scale PV plants caused by shadows due to passing clouds can compromise grid stability. Traditionally, some kind of energy storage systems (ESS) is proposed as the solution ...
A comparative study of degradation and performance of thin film photovoltaic generators versus a multi-crystalline generator
(2013)
info:eu-repo/semantics/conferenceObject,
Thin film solar cells (TFSC) are supposed to have higher energy yield rates than crystalline silicon (Si-x) mainly possible by some enhancements like lower temperature coefficient and higher absorption of diffuse light. ...
