Control and stability of Ac/Dc microgrids
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2017)
The current society is facing several challenges related to the field of energy, such as the high dependency on fossil fuels, the constant increment in the energy consumption and the environmental problems caused by these ...
Power Capability Boundaries for an Inverter Providing Multiple Grid Support Services
(MDPI AG, 2020)
It is getting more common every day to install inverters that o er several grid support services in parallel. As these services are provided, a simultaneous need arises to know the combined limit of the inverter for those ...
Equivalence of primary control strategies for AC and DC microgrids
(MDPI, 2017)
Microgrid frequency and voltage regulation is a challenging task, as classical generators with rotational inertia are usually replaced by converter-interfaced systems that inherently do not provide any inertial response. ...
Dual Inertia-Emulation Control for Interlinking Converters in Grid-Tying Applications
(IEEE, 2021)
Electric grids are undergoing several changes, mostly driven by the replacement of classical highly-inertial generators by converter-interfaced generation and storage systems. This entails the reduction of inherent inertia ...
Impedance-Based Stability Evaluation of Virtual Synchronous Machine Implementations in Converter Controllers
(IEEE, 2018)
This paper presents a stability evaluation of two Virtual Synchronous Machine (VSM) implementations in the control of Voltage Source Converters (VSCs): a current-controlled (CCVSM) and a voltage-controlled (VCVSM) version ...
Current References Limitation Method Considering Voltage and Current Maximums for STATCOMs Providing Simultaneously Reactive Power and Current Harmonics
(IEEE, 2022)
This article focuses the analysis on a static synchronous compensator (STATCOM) that operates simultaneously providing reactive power and several current harmonics of different frequencies (active power filter or active ...
Stability tool for electric power systems with a high penetration of electronic power converters
(Elsevier B.V., 2022)
The increasing use of electronic converters is making possible the development of more sustainable, efficient, and reliable electric power systems, but it is also introducing new challenges that need to be addressed. Power ...
Hybrid AC/DC microgrid mode-adaptive controls
(InTech, 2017)
The lack of inertial response at microgrids is usually compensated by configuring primary controllers of converter‐interfaced devices to contribute in the transient response under power disturbances. The main purpose of ...
Droop control operation strategy for advanced DC converter-based electrical railway power supply systems for high-speed lines
(Elsevier Ltd., 2022)
Advanced DC converter-based electrical railway power supply systems are very promising power supply configurations for the electrification of high-speed lines. Their full controllable converter-based traction substations ...
Hybrid ac/dc microgrids. Part II : Review and classification of control strategies
(Elsevier, 2015)
Microgrids are envisioned as one of the most suitable alternatives for the integration of distributed generation units in the utility grid, as they efficiently combine generation, energy storage and loads in the same ...
