The development of new technologies has provided a fast growth of the wind turbine industry. Worldwide governments have presented financial programs of alternative energy sources. The increase of wind turbines in electrical systems has led the system operators to make codes to regulate the integration of wind farms with the network, setting minimum conditions for supportability. The aim of this paper...
The share of distributed generation (DG) in the power system generation is increasingly grown up and for the economical and technical reasons; their integration is deeply concentrated by the researchers. This paper reintroduces the integration of distributed energy resources (DER), i.e. DGs, controllable loads and energy storages, into micro grid and virtual power plant (VPP) and also reviews their...
This paper presents a microgrid paradigm with both DC and AC links, which may provide an effective way to integrate a heterogeneous set of small-size distributed energy resources into the existing electric power infrastructure. The collection of aggregated energy resource units at each level represents those distributed resources to the upper level as a single self-regulated entity (as a DC or AC,...
The growth in distributed energy resources has the potential to reduce system stresses caused by transmission grid congestion by supplying power and voltage regulation closer to load centers. However, the additional voltage regulation provided by these resources can mask the onset of voltage collapse. Local voltage support flattens the slope in the upper region of the power-voltage nose curve. Coordinating...
