Energy storage configuration for substations

What is the purpose of energy storage configuration?

From the time dimension, when the short-term (minute-level) output volatility of new energy needs to be suppressed, the main purpose of energy storage configuration is to offset the penalties of output deviations.

How can new energy suppliers use energy storage facilities?

New energy suppliers can use energy storage facilities by installing, renting or purchasing external services, so as to control the power output within the allowable fluctuation range.

What are hub substations (HS/S)?

In this study, this extended system is noted as hub substations (HS/S), which can aid in the operation of both TSO and DSO and achieve economic efficiency. The key contributions of the study can be summarized as follows.

Are ESS-equipped substations a viable solution for resolving site constraints?

Especially, recent development of hub substations (HS/S) equipped with ESS, applicable for resolving site constraints if implemented as mobile transformers, is expanding the development of ESS-equipped facilities. However, these units require centralized control strategies considering variability within integrated networks.

Should electric vehicle charging be a ESS management scheme for individual substations?

While studies on electric vehicle charging considering the variability of renewable energy or load are widely studied, ESS management scheme for individual substations requires further optimization, especially considering the state of distributed sources at lower levels and transmission system operators.

Why is energy storage important in a power system?

Energy storage of appropriate capacity in the power system can realize peak cutting and valley filling , reduce the pressure caused by the anti-peak regulation of new energy units, and smooth the fluctuation of new energy output .
