Requirements for volume ratio of energy storage power stations

How is storage sized in CEM?

In CEM, storage is sized either assuming a predefined duration (i.e., a fixed energy-to-power ratio, , , ) or independently optimizing the power and energy capacity of system storage, assuming distinct costs for its energy and power components , , .

What is the res penetration target for the power system of Greece?

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.

Which storage capacity is best for NET system economic benefit?

Best results in terms of net system economic benefit are obtained for an aggregate storage capacity between 1000 MW and 1250 MW, when the contribution of storage to capacity adequacy is not considered (the bau counterfactual scenario).

What is the maximum benefit of a solar PV-driven renewables mix?

Maximum benefit is obtained for aggregate storage capacities from 1250 to 1750 MW. A solar PV-driven renewables mix imposes needs for additional 500 MW of storage. 1. Introduction The decarbonization of the electricity sector involves the transformation of the entire generation system, with increasing reliance on renewable energy sources (RES) .

Does storage contribute to resource adequacy?

In this evaluation, the contribution of storage to resource adequacy is also considered , , properly monetized. 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, .

What is a good storage capacity?

When the value of the firm capacity provided by storage is considered (the do-minimum counterfactual scenario), storages of an aggregate capacity of 1500 MW to 1750 MW yield the best results. Maximum annual benefits reach ~70 M€/y and ~110 M€/y in the bau and do-minimum cases.
