Abstract

This paper proposes a versatile and modular Multi-Terminal High Voltage Direct Current (MTDC) network model with a compact matrix formulation. There will be a growing deployment of MTDC grids, necessitating the development of novel tools and models for their analysis and simulation. The first contribution of the paper is the proposal of a new MTDC network model using graph theory. The model preserves the dynamics of the grid and is flexible to adapt to different topologies and sizes. The second contribution is the implementation of the proposed MTDC model in an integrated software framework for the dynamic simulation, which incorporates an automatic flat-start initialization from an AC/DC power flow. The tool is developed in Matlab/Simulink and it includes the possibility to simulate various types of contingencies including different types of short-circuits, line clearances and converter outages, both for monopolar and bipolar DC networks. This tool is designed for time domain simulation and small-signal analysis of systems, including MTDC networks, with the objective of studying the dynamics of novel converter models and control strategies. The results demonstrate the functionalities of the proposed MTDC network model and simulation tool, highlighting the importance of network dynamics in simulations with power electronic converters.

期刊介绍： Electric Power Systems Research is an international medium for the publication of original papers concerned with the generation, transmission, distribution and utilization of electrical energy. The journal aims at presenting important results of work in this field, whether in the form of applied research, development of new procedures or components, orginal application of existing knowledge or new designapproaches. The scope of Electric Power Systems Research is broad, encompassing all aspects of electric power systems. The following list of topics is not intended to be exhaustive, but rather to indicate topics that fall within the journal purview. • Generation techniques ranging from advances in conventional electromechanical methods, through nuclear power generation, to renewable energy generation. • Transmission, spanning the broad area from UHV (ac and dc) to network operation and protection, line routing and design. • Substation work: equipment design, protection and control systems. • Distribution techniques, equipment development, and smart grids. • The utilization area from energy efficiency to distributed load levelling techniques. • Systems studies including control techniques, planning, optimization methods, stability, security assessment and insulation coordination.
