Abstract

Energy storage systems (ESS) are becoming a key component for power systems due to their capability to store energy generation surpluses and supply them whenever needed. However, adding ESS might eventually have unexpected long-term consequences and may not necessarily help in reducing CO2 emissions; mainly because they can store energy from any source and add some inefficiencies. Thus, it is important to accurately assess the impact they could have on the long-term prospects of the overall power system.
