Wind energy to thermal and cold storage—A systems approach

In this paper wind energy to thermal and cold storage scenarios was examined to enable high wind integration through converting renewable electricity excess into thermal or cooling energy, saving part of the energy used in an area and eliminating the need to possibly build a new coal fired plant. Case studies in Crete Island (not interconnected to the power grid of Greek mainland) with onshore wind power installed were investigated. The aim of this work was to review the options for greater integration of renewables into the grid and the main idea was to analyze the wind to thermal and to cold storage according to the needs of two small municipalities.

► A freezer and a heating system can store electricity “to-be-curtailed”. ► WF operator's remuneration is at least double compared to the curtailment earnings. ► Under this methodology the end user saves money spent for the electricity bill. ► From a systems perspective, the ACFs increased by 3.27% (WF1) and 3.18% (WF2).
