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 ...
An Interoperable EMS for the Provision of Grid Services with Hybrid Energy Storage Systems
(IEEE, 2022)
This paper proposes an interoperable energy management system (EMS) for grid-connected HESSs, enabling the provision of ancillary services to the grid. Power systems are evolving towards a more renewable and decentralised ...
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 ...
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 microgrids. Part I : Review and classification of topologies
(Elsevier, 2015)
Microgrids have been widely studied in the literature as a possible approach for the integration of distributed energy sources with energy storage systems in the electric network. Until now the most used configuration has ...
Comparative small-signal evaluation of advanced grid-forming control techniques
(Elsevier B.V., 2022)
This paper presents the small-signal modelling and analysis of the most recent grid-forming control techniques, namely the matching control (MC) and the dispatchable virtual oscillator (dVOC). These are compared to more ...
Experimental test bench for testing DC microgrid control strategies
(IEEE, 2017)
During the last decades the number of microgrids and their research have increased notably, as they offer a high versatility for the integration of distributed generation (DG) units and renewable energies. Among the different ...
