voltage profile and losses are important factors in a distribution network in which there arevariety of ways to improve them. in this paper, distributed generation (dg) is used as a solutionto improve the above characteristics. backward/forward sweep load flow algorithm is used dueto the inefficiency of usual load flow algorithms because of high r/x ratio and their lack ofconvergence in distrib...

a detailed model of wind power station, including double fed induction generator, dfig is presented in this paper. two control mechanisms are included in the model. the inner control system uses stator flux oriented control for the rotor side converter and grid voltage vector control for the grid side converter. the outer control system is used for wind turbine pitch angle. pscad/emtdc is used ...

Distributed Energy Resources (DER) are systems that produce electrical power at the site where the power is needed. If only electrical power is used then the technology is called Distributed Generation (DG). The objective of this paper is to study a novel more than five level multistring inverter topology for DERs based DC/AC conversion system. The distributed energy resource based single-phase...

With the development of new energy, a cost-effective reactive power compensation scheme is essential to voltage stability system for small-capacity distributed generation. This paper proposes coordinated control inverter cluster which based on support capability photovoltaic inverter. Moreover, by using angle vectors, distribution algorithm proposed solve poor quality point common coupling conn...

As the deployment of distributed generation continues, an increasing number of DC/AC power inverters will be interfaced into the electric grid. Groupings of these power inverters, along with distributed storage and load, are referred to as microgrids. Microgrids offer the potential for unprecedented reliability and flexibility, but also pose new control challenges. Inverters in microgrids must ...

Due to disperse nature of renewable energy resources (RES), electricity generation is often taking place in small scale but main drawback is power quality. So to improve power quality issues, integration of renewable energy into the utility grid can be done either at transmission level or the distribution level depending on the scale of generation. The renewable resources like solar energy, win...

In the modern era, distributed generation is considered as an alternative source for power generation. Especially, need of the time is to provide the three-phase loads with smooth sinusoidal voltages having fixed frequency and amplitude. A common solution is the integration of power electronics converters in the systems for connecting distributed generation systems to the stand-alone loads. Thu...
