Economic evaluation conditions for independent energy storage

What are the market clearing results for energy storage systems (ESSs)?

As the market clearing results for ESSs depend on the difference between charging and discharging offering prices instead of the separate values , the discharging offering prices of ESSs are set to zero while the charging offering prices are set at the range of 260−360 ¥·kW −1. Table 3. Offering data of energy storage systems (ESSs).

Are energy storage technologies economically viable?

Through a comparative analysis of different energy storage technologies in various time scale scenarios, we identify diverse economically viable options. Sensitivity analysis reveals the possible impact on economic performance under conditions of near-future technological progress.

What are the potential value and development prospects of energy storage technologies?

By means of technical economics, the potential value and development prospects of energy storage technologies can be revealed from the perspective of investors or decision-makers to better facilitate the deployment and progress of energy storage technologies.

What are energy storage systems (ESSs)?

The energy storage systems (ESSs) could realize peak load shifting and provide faster response speed and higher tracking accuracy in power regulation . Most countries have focused on exploiting the values of ESSs.

Is thermal energy storage a cost-effective choice?

Sensitivity analysis reveals the possible impact on economic performance under conditions of near-future technological progress. The application analysis reveals that battery energy storage is the most cost-effective choice for durations of <2 h, while thermal energy storage is competitive for durations of 2.3–8 h.

Does thermal energy storage have a good economic performance?

In the assumed scenario, thermal energy storage has a strong competitiveness when the duration is 2.3–8 h, and Pumped storage gains economic advantages from 2.3 h, and dominates from 7.8 h and beyond. Thermal energy storage achieved the best economic performance in Region 3.
