微网存在两种典型的运行模式：离网模式和并网模式。同时，两种模式之间的切换也应该实现无缝切换。考虑 到采用主从控制以实现无环流的微网中主变换器在微网中的重要地位，本文采用V/f电压控制做为离网时变换器控制方法， 通过逐步调整变换器输出电压使其跟随电网电压实现离网到并网的无缝切换；-There are two typical micro-grid operation modes: off-grid and grid mode mode. At the same time, switching

This paper presents a scalable integration approach for algorithms and models written in fourth generation (programming) languages for massive Smart Grid simulations as well as applications. While fourth generation languages (4GL) focus on rapid

This impact may manifest either in positive or negative manner depending on the type of DG and its characteristics. The ever increasing levels of the penetration of DG requires a regulation that enables existing DG units connected to the grid without
