Considering the energy arbitrage and flexibility needs of the Greek power system, a mix of short (~2 MWh/MW) and longer (>6 MWh/MW) duration storages has been identified as optimal. In the short run, storage is primarily needed for balancing services and to a smaller degree for limited energy arbitrage.
While the optimal configuration of the ESSs does not have particularly strict requirements for calculating time, it is still appreciated for enhancing computational efficiency. For obtaining the objective function, the hybrid GWO-PSO outperforms the GWO in the 118-node system, and it is inferior to the GWO in the 33-node system.
The development of storage in Greece has only just begun: this year has been the big "kick-start" and there is now a common understanding of the needs and requirements and the steps to be taken to ensure an adequate identification and prioritization of all necessary actions.
The power system of Greece is used as a case study, adopting a RES penetration target of around 60%, as foreseen in the National Energy and Climate Plan (NECP) for 2030, . The generation portfolio of the Greek system in the mid-term horizon to 2030 is well-defined in the NECP, with storage being the main asset yet to be identified.
Even though electricity storage is recognized as a prerequisite for the decarbonization of the power sector, the development of storage facilities is still facing legal/regulatory barriers and investment feasibility concerns.
1 During 2020-2021, Greece has experienced a new explosion of licensing interest for RES stations. The application to the Regulator in mid-2021 exceeded 9000 MW, with most of them having already acquired Electricity Producer Attestation (EPA), far beyond the needs of our national system.
