Hybrid AC/DC microgrid can make full use of different kinds of renewable energy to meet the needs of various types of loads. The bidirectional converters become the link between dc and ac region. In this paper, H8 robust control method is proposed to stabilize the both-side voltages of the bidirectional converters where it is transformed to a mix sensitivity problem. When there are perturbations on...
Microgrid allows high penetration of renewable energy sources, and provides technical foundation for the grid connection and operation of distributed generations (DGs). The negative impacts caused by DGs should be reduced inside the microgrid. Photovoltaic (PV) generation is one of the major distributed energy sources, and the performance of PV generation systems connected to microgrid directly affects...
Considering different application scenarios and questions to be solved, electromagnetic transient simulation and transient stability simulation are rarely performed simultaneously for the calculation of traditional bulk power system, which are quite different from element modeling to simulation algorithm. But it's not true for the analysis and calculation of microgrid and active distribution system...
Distributed generation in microgrid is mainly composed of new energy and renewable energy resources. The maximum power point of the PV cell array is various from time to time with the change of circumstance and load. The fuzzy control can react to the environment change quickly and keep the photovoltaic system work on its maximum power point all the time. However, the limitation in the fuzzy control...
