Kitga energy storage configuration requirements

What are the EC requirements for energy storage systems?

During a scheduling time period, the EC requires the energy storage system to provide dynamic standby power of at least 50 kW and a dynamic standby capacity of at least 100 kWh. The battery multiplicity constraint is set to 0.5. The charging and discharging efficiencies are both set to 0.95. The values of K E and K L are both set to 0.2. Fig. 4.

Why are energy storage devices subject to minimum power constraints?

At the same time, the energy storage device is subject to minimum power constraints for charging and discharging to prevent repeated fluctuations at the thresholds, eliminating residual power and improving the stability of charging and discharging states during optimization.

Why should energy storage facilities be installed?

For new energy units, proper deployment of energy storage facilities can promote the consumption of excess generation, increase the option of selling electricity in the high price period, participate in the competition auxiliary service market, and improve the return on total life cycle assets.

Does energy storage provide a complementarity between load and power source?

This approach does not demonstrate the complementarity of the load and power source in different locations during the same time period, nor does it reflect the flexibility of the energy storage device. In the Case 2 analysis, energy storage serves solely to transfer load and avoid peak and valley tariffs at certain times.

What are the constraints of distributed energy storage?

Furthermore, the power capacity of distributed energy storage must meet the constraint of battery charging rate (C-rate). This means that the ratio of battery power to capacity must be subject to the C-rate constraint. These constraints are given in Eq. (6): (6) P e s s, i m a x ≤ β r a t e E e s s, i m a x U e s s, i p o s ∈ {0, 1}

Do distributed energy storage devices meet backup conditions?

Distributed energy storage devices must fulfill backup conditions, which entails ensuring that there is always an available energy storage device for backup during different scheduled hours and that the backup capacity and power meet the specified requirements.
