The paper deals with the multilevel converters control strategy for photovoltaic system integrated in distribution grids. The proposed control scheme ensures the injection of the generated power in the distribution grid with fast dynamic response, while providing an additional active power filtering capability providing the required harmonic and reactive currents to be considered. The control s...

The recently observed increase in distributed generation based on renewable energy sources (DG/RES) in the European electricity system is most likely to continue or even increase its growth rate in the future. Distributed Generation (DG) as one core focus of this paper is mainly meant to be connected to distribution grid areas. Thus, scenarios for DG/RES development on distribution level are de...

Spatial variability plays an important role in nonlinear hydrologic processes. Due to the limitation of computational efficiency and data resolution, subgrid variability is usually assumed to be uniform for most grid-based rainfall-runoff models, which leads to the scale-dependence of model performances. In this paper, the scale effect on the Grid-Xinanjiang model was examined. The bias of the ...

Article history: Received: 22.10.2014. Received in revised form: 13.12.2015. Accepted: 14.12.2015. The connection of distributed sources and their impact on distribution grid has been the subject of intensive research in the last two decades. Creating a favorable environment for the production of electrical energy from renewable energy sources in many countries around the world made an evident ...

Computational tasks are split into many modules and the resources of participating nodes of Grid are shared with to solve intensive jobs. Since the Grid participants are open in many cases, the respective providers do not maintain reputation in providing their promised services. Therefore ‘Trust’ worthiness of nodes of clusters of Grid is determined through various techniques with several param...

The utilization of power systems in Germany has changed considerably due to a fundamental shift in the variety of power generation during the last years. Since most of the renewable power plants are connected on distribution level, these grids are affected fundamentally. Smart distribution systems are one important element to handle the new challenges. Therefore the authors of the present paper...

In this Master thesis the integration of PV systems and Battery Energy Storage Systems (BESS) in the distribution grid is examined. The simulation framework and the algorithms that were implemented in this thesis are applicable to general distribution grids. However, the main focus of this thesis is to study the concrete example of a distribution grid in the city of Zurich. The electric utility...
