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.
How to constrain the capacity power of distributed shared energy storage?
To constrain the capacity power of the distributed shared energy storage, the big-M method is employed by multiplying U e s s, i p o s (t) by a sufficiently large integer M. (5) P e s s m i n U e s s, i p o s ≤ P e s s, i m a x ≤ M U e s s, i p o s E e s s m i n U e s s, i p o s ≤ E e s s, i m a x ≤ M U e s s, i p o s
Does energy storage reduce overvoltage?
The peak voltage is lower, suggesting that the energy storage device significantly suppresses the overvoltage issue. Compared to the scenario where shared energy storage is not set up (Case 0), the DNO in Case 1 can utilize energy storage services to regulate voltage distribution and enhance the distribution network’s security and reliability.
Does a case1 energy storage device reduce the overvoltage issue?
The figure indicates that the voltage of Case1 is closer to the reference value of 1, the distribution range is narrower, and the voltage stability is stronger. The peak voltage is lower, suggesting that the energy storage device significantly suppresses the overvoltage issue.
How does a distribution network use energy storage devices?
Case4: The distribution network invests in the energy storage device, which is configured in the DER node to assist in improving the level of renewable energy consumption. The energy storage device can only obtain power from the DER and supply power to the distribution network but cannot purchase power from it.
