Modern power systems are expected to accommodate more and more renewable energy into the grid to minimize greenhouse gas emission from energy sector. Large scale adoption of solar and wind energy creates instability due to the intermittent nature of these sources. Major problem associated with these sources are harmonics, fluctuation or even unavailability of useful energy during peak demand. Moreover integration of these sources in different phases can cause phase unbalance and power quality (PQ) issues in the network. Energy Storage (ES) can overcome some of these PQ problems by buffering a...
