Round-trip efficiency is the ratio of useful energy output to useful energy input. (Mongird et al., 2020) identified 86% as a representative round-trip efficiency, and the 2022 ATB adopts this value. In the same report, testing showed 83-87%, literature range of 77-98%, and a projected increase to 88% in 2030.

The energy market price including, global adjustment cost, demand charges, hourly energy price are adopted from the available data of IESO in Ontario, Canada [24,25,26]. It is important to mention here that the uncertainty in the load demand and market prices is fully considered in the data processing step.
It can also be seen from Fig. 2 that as the capacity and power of the energy storage system increase, the economic profit of the energy storage system gradually decreases. If there is no energy storage system, the thermal power unit can only absorb part of the renewable energy, and the total amount of abandoned wind during
