Standardized Assessment Framework for Design and Operation of Weak AC Grid-Connected VSC Controllers

نویسندگان

چکیده

Significant research attention is focused on the stability and control of voltage-source converters (VSCs) in weak ac grids. However, assessment VSC strategies has never been standardized, such that novel solutions proposed literature are not objectively evaluated against current best-practice. This paper establishes a comprehensive, standardized framework for grid-connected controllers, which allows objective comparison controllers under development established methods already operation. The consists tuning stage, time-domain analysis frequency-domain to form complete evaluation can be applied its full aggregated or as individual steps. Three namely vector control, power-synchronization virtual synchronous machine, compared this using small-signal models, simulations hardware-in-the-loop Real-Time Digital Simulation (RTDS) experiments demonstrate versatility robustness with very different structures.

Controllers For A VSC-HVDC Link Connected To A Weak AC System

In this paper, the interconnection of a strong AC system to a weak AC system by using a Voltage Source Converter (VSC) based High Voltage DC (HVDC) transmission system is investigated. In this work, the weak AC system considered is an island system comprised of synchronous generators and passive load. Analysis is carried out for UPF load and inductive load. The ac filter requirement to achieve ...

A Generalized Class of Stationary Frame-Current Controllers for Grid-Connected AC–DC Converters

Within power systems, high-power pulsewidth-modulated ac–dc converters are used in flexible ac transmission systems controllers and for interfacing renewable energy sources to the grid. These converters traditionally employed PI controllers designed in the synchronous -frame with decoupling of and axes. Recently, stationary -frame proportional-resonant (PR) controllers have been proposed. Thoug...

Model Predictive Control of Distributed Energy Resources with Predictive Set-Points for Grid-Connected Operation

This paper proposes an MPC - based (model predictive control) scheme to control active and reactive powers of DERs (distributed energy resources) in a grid - connected mode (either through a bus with its associated loads as a PCC (point of common coupling) or an MG (micro - grid)). DER may be a DG (distributed generation) or an ESS (energy storage system). In the proposed scheme, the set - poin...

An "ac Inductor" Based Grid Connected Inverter

This study proposes a soft switched Output Current Sourcing (OCS) grid connected inverter that applies a high frequency isolation transformer. Current sourcing at the output implies that, ideally, the injected current will be independent on the load voltage. The current injected to the line is controlled by varying the switching frequency and dithering at low currents. The system does not requi...
