    Abstract: A power system responsible to supply reasonable level of reliable, qualitative electricity supply to its consumers in an acceptable price. Reasonable level is defined as one balancing the need for power supply and the cost involved. This includes increasing adequacy and security of the system. If the frequency and duration of outages can be reduced... Show More

    Abstract: Microgrids have the potential to provide customers with improved power quality and reliability. However, there are technical challenges related to the operation and control of microgrids and the distributed energy source (DERs) that constitute them. Resonance caused by the low-pass filters connected to the voltage source inverters of the DERs is on... Show More
