Transformation from electricity to gases and vice versa can add further storage capacity and flexibility to the energy system. . In this context, this paper identifies the synergies among flexibility options under restrictions on transmission expansion or increased costs of energy storage. Itcontributestodeterminingwhetherinvestments in energy storage and/or transmission expansion offer the least-cost transition and. . Complementarity may refer, for example, to using the excess generation from a wind farm to charge a storage system when there is insufficient demand and discharging it when demand is high and wind farm output is low, as depicted in Figure 1. In addition, a. . Energy storage coupling refers to a systematic integration of various energy storage technologies and systems to enhance efficiency, flexibility, and reliability in energy supply, especially in the context of renewable energy sources.
