Power Quality Challenges and Solutions for Microgrids

Por: EMMA . en: ,


Microgrids are deemed as one of the main building blocks of the smart grids; since they are able to facilitate the implementation of many smart grid functions. On the other hand, the proliferation of different nonlinear and single-phase loads in electrical systems has resulted in voltage harmonics and unbalance as two common power quality problems. In addition, harmonic resonances can be excited giving rise to a significant increase of the voltage distortion. These phenomena can cause variety of problems such as protective relays malfunction, overheating of motors and transformers and failure of power factor correction capacitors.

Therefore, in this course, measurement, compensation, and damping of such power quality problems will be addressed through several basic and advanced control methodologies.
