This study presents an application for a series VSC (voltage source converter) in distribution grids power flow management. Series devices have been widely studied FACTS (flexible AC transmission systems), however, more recently these gained increased interest applications loading balance medium voltage grids. As the number of distributed generation (DG) units increases, increasing capacity and...

Abstract In order to realize the coordination and integration optimization of power system itself, this paper constructed mathematical model hybrid solved multi-objective problem heating through optimized particle swarm algorithm. Based on back-to-back VSC-HVDC grid-connected composite system, studied integrated control strategy device achieve simultaneous parallel tie line currents. At same ti...

Distribution grid is the medium and low voltage part of a large power system. Structurally, the majority of distribution networks operate radially, such that energized lines form a collection of trees, i.e. forest, with a substation being at the root of any tree. The operational topology/forest may change from time to time, however tracking these changes, even though important for the distribut...

In recent years, several applications have been proposed in the context of distribution networks. Many these can be formulated as an optimal power flow problem, a mathematical optimization program which includes model steady-state physics electricity network. If network loading is balanced and lines are transposed, simplified to single-phase equivalent model. However, assumptions do not apply l...
