Battery energy support to Cascaded H-Bridge converter fed large scale PV system during unbalanced power generation
https://www.sintef.no/en/publications/publication/1895516/
In this paper, a large-scale grid-connected PV system along with a battery energy system is analyzed for unbalanced power generation in the PV system. The system is connected to the medium-voltage grid through a Cascaded H-Bridge converter where each cell of the converter has individual PV and an...

V2G Potential Estimation and Optimal Discharge Scheduling for MMC-based Charging Stations
https://www.sintef.no/en/publications/publication/1880957/
This paper investigates the vehicle-to-grid (V2G) potential of the large scale electric vehicle (EV) charging infrastructures where the grid-side interface is based on a Modular Multilevel Converter (MMC). In this topology, each phase of the grid-side interface consists of two arms, each of which...

Configuration and model order selection of frequency-dependent π-models for representing dc-cables in small-signal eigenvalue analysis of HVDC transmission systems
https://www.sintef.no/en/publications/publication/1798045/
Eigenvalue-based analysis of small-signal dynamics in High Voltage Direct Current (HVDC) transmission systems requires cable models that are compatible with a state-space representation. While distributed parameter models accounting for frequency-dependent effects are inherently incompatible with a...

Load Balancing of a Modular Multilevel Grid Interface Converter for Transformer-Less Large-Scale Wireless Electric Vehicle Charging Infrastructure
https://www.sintef.no/en/publications/publication/1863940/
This paper analyses the requirements for load balancing of a new transformer-less grid interface topology for large-scale electric vehicle (EV) charging infrastructures. The proposed configuration utilizes a Modular Multilevel Converter (MMC) to supply wireless EV chargers from each module. The...

A Modular Approach to Large-Signal Modeling of an Interconnected AC/MTDC System
https://www.sintef.no/en/publications/publication/1847261/
The so-called modular modeling of interconnected AC/MTDC (Multi-Terminal DC) systems aids their synthesis and analysis by decomposing it into structural modules (e.g. voltage-source converter, synchronous generator, AC line, DC line) and by exploring the patterns of interconnection that yield the...

Locating Generators Causing Forced Oscillations Based on System Identification Techniques
https://www.sintef.no/en/publications/publication/1847243/
This paper presents a method to locate the source of forced oscillations in power grids caused by maloperation of turbine-governor systems. The transfer function between the grid frequency and the output active power is first estimated for each generator in normal operation condition. The turbine...

P-HiL Evaluation of Virtual Inertia Support to the Nordic Power System by an HVDC Terminal
https://www.sintef.no/en/publications/publication/1847240/
This paper provides an assessment of the effect from virtual inertia provided by an HVDC converter terminal on the Nordic power system. The analysis is based on results from Power-Hardware-in-the-Loop (P-HiL) tests with a laboratory-scale Modular Multilevel Converter (MMC) representing an HVDC...

Optimized Allocation of Loads in MMC-based Electric Vehicle Charging Infrastructure
https://www.sintef.no/en/publications/publication/1846209/
Utilization of the modular multilevel converter (MMC) topology can enable transformer-less interfacing between electric vehicle (EV) charging infrastructure and the power distribution grid. Such configurations are claimed to significantly reduce the system costs, space requirements and complexity...

Evaluation of Inertia Emulation Strategies for DC- Voltage-Controlled and Power-Controlled Converter Stations in HVDC Interconnections
https://www.sintef.no/en/publications/publication/1823089/
This paper presents an evaluation of two control schemes for virtual inertia support from the converter terminals of an HVDC interconnection. A point-to-point interconnection between asynchronous power systems is assumed, where one terminal controls the dc-side voltage while the other controls the...
