Problems with energy storage dispatching and operation

How do energy dispatch strategies reduce energy costs?

To reduce energy costs and ensure the balance of power supply and demand, energy dispatch strategies are usually designed to regulate the power of distributed energy components.

Why is energy dispatch a multi-objective problem?

Frequently fluctuating photovoltaic energy and wind energy lead to thinning of the anode catalytic layer and increasing polarization resistance of the electrolyzer . Therefore, economy and longevity should be considered as multi-objectives in the energy dispatch problem.

Why are battery energy storage systems a problem?

Moreover, battery energy storage systems (BESS) are usually used for renewable energy storage, but their capacity is constant, which easily leads to the capacity redundancy of BESS and the abandonment problem of wind and solar energy , , .

Do energy storage devices play a role in integrated energy system?

Reference [ 20] explored the two-stage distributional robust coordinated scheduling for gas-electricity integrated energy system. In the construction of an IES, the role of energy storage devices cannot be ignored.

What challenges does Bess face in energy storage?

As a traditional energy storage device, BESS faces challenges in changing climates and low-cost energy storage due to its fixed capacity and high material costs. Hydrogen energy storage is gradually emerging in energy storage due to its scalability and non-polluting feature.

Does the multi-objective energy dispatch strategy reduce electrolyzer volatility?

Compared with the single-objective economic energy dispatch strategy, the application of the multi-objective energy dispatch strategy only increases the daily average dispatch cost by 0.055$ but reduces the electrolyzer volatility index by 49 %.
