It has been proven that energy storage can largely assist increased penetration of renewables into the grids. This is more important in autonomous grids as the one in Cyprus. One of the most technologically advanced and mature energy storage technologies is Pumped- Hydro (PH). PH is also considered as the most suitable storage technology to achieve high Renewable Energy Sources (RES) penetration levels in autonomous power systems, such as Cyprus’, avoiding unnecessary RES energy curtailment. The existing water reservoirs in Cyprus provide an important potential for energy storage application at relatively reduced cost providing many side benefits. Sizing and siting of potential PH Storage (PHS) systems are evaluated within the present study. It is shown that existing reservoirs can cope with the energy storage demands for high renewables’ penetration exceeding the current Cyprus state goals. DISPA-SET model is used in order to quantify impact and implications of the potential energy storage projects and in order to identify the optimal transmission grid behavior (in terms of re-scheduling operation of conventional units). Conventional units will be assisted to achieve more efficient operational modes with less idle loads, significantly enhancing the operational safety of the grid. Simulations for the selected scenarios were performed both for the Cypriot isolated-autonomous grid and for an interconnected grid between Cyprus, Greece and Israel.
The present study performed in the framework of “Storage & Renewables Electrifying Cyprus” project (SREC, INTEGRATED/0916/0074). SREC project is co-financed by the European Regional Development Fund and the Republic of Cyprus through the Research Innovation Foundation.
