Optimal configuration of battery energy storage system for peak-load

As is well known, the anti-peaking characteristic of wind generation leads to evident curtailments of wind farms. With high energy density and flexible installation position, the battery energy storage system (BESS) can provide a new routine to relax the bottleneck of the peak-load regulation, conducive to the absorption of wind power and the economy of system operation.

Optimization strategy of combined thermal-storage-photovoltaic

Energy storage is a good way to solve the challenges brought by the access of high proportion of renewable energy and plays an important role in peak load regulation [6], [7], [8]. Energy storage can store the excess renewable energy while the period of load valley and release the stored energy while the period of load peak, so as to smooth the demand curve.

6 FAQs about [Seychelles energy storage peak load regulation]

What is the Seychelles energy plan?

It targets an ambitious transformation and diversification of the Seychelles’ currently 85 MW diesel-dominated electricity generation capacity (on Mahé, Praslin and La Digue), aiming at replacing diesel generators with domestic and international public and private financing.

Is there a trade-off between energy storage and peak regulation?

In the meantime, the trade-off between deploying energy storage and leveraging the deep peak regulation capacity of existing thermal generators remains to be explored.

What does the Seychelles government do?

The Seychelles Government is committed to providing adequate, reliable and affordable energy to meet future energy consumption needs and to underpin strong economic growth through consumable energy initiatives. The Seychelles enjoy favourable conditions for renewable energy (RE) resources, such as wind and solar.

What is the power and capacity of Es peaking demand?

Taking the 49.5% RE penetration system as an example, the power and capacity of the ES peaking demand at a 90% confidence level are 1358 MW and 4122 MWh, respectively, while the power and capacity of the ES frequency regulation demand are 478 MW and 47 MWh, respectively.

What is the optimal energy storage system capacity?

With a lower penetration rate, e.g., below 18 % in Scenario 5, the optimal energy storage system capacity is approximately zero, indicating that in the presence of a low share of renewable energy, flexibility from existing thermal power units is sufficient for renewable accommodation, and no additional flexible resources are needed.

Does penetration rate affect energy storage demand power and capacity?

Energy storage demand power and capacity at 90% confidence level. As shown in Fig. 11, the fitted curves corresponding to the four different penetration rates of RE all show that the higher the penetration rate the more to the right the scenario fitting curve is.
