In this paper, the principle of modularity is used to derive the different multilevel voltage and
current source converter topologies. The paper is primarily focused on high-power …

The ever increasing progress of high-voltage high-power fully controlled semiconductor
technology continues to have a significant impact on the development of advanced power …

The advantages of VSC-HVDC compared with the traditional HVDC are introduced in the
thesis. Then the necessity and challenges of developing DC circuit breaker used in large …

In this paper, a new unified method for power flow calculation in AC grids with embedded
multi-terminal HVDC systems based on voltage source converter is proposed. In this method …

Multi-terminal HVDC systems have recently become an attractive option for interconnection
of isolated AC systems such as offshore wind farms and oil platforms to asynchronous large …

Nowadays, due to lack of a strong interconnection between electric power systems within
EU, there is a concern about the restricted power exchange. On the other hand, one of the …

The three-phase H-bridge or NPC converters are commonly adopted converter topologies
for FACTS devices. Both the converters are classified as multilevel converters capable of …

Flexible AC transmission systems (FACTS) are defined by IEEE as “alternating current
transmission systems incorporating power-electronic based and other static controllers to …

Recently, with the advent of power electronics, the use of DC technology might be an
attractive option to be considered for energy transmission and distribution in power systems …

ABSTRACT A solar-PV system is generally connected to distributed generation (DG) by the
utility grid. The solar inverter retains some capacity after active power generation. Reactive …
