An overview of Hybridization of Power sources for Ancillary Service

Abstract

International audienceIncreasing Renewable Energy Sources (RESs) mix in the power grids, with advanced power electronic converters are not only bringing green energy to meet the demands but also are posing threats to the power system because of their impacts on the frequency/voltage stability and short circuit current mitigation issues. Obviously, with large hydro storage systems like the Pumped Storage Plants (PSPs) or other storage technologies, problems can be met with solutions increasing the grid stability and reliability. But the characteristics of different technologies does make the decision challenging. This paper gives an overview of how hybridization of power sources using different storage technologies can mitigate the impacts of the RES penetration into the grid
