Should power system operators consider demand response and storage?

Power system operators can weigh the benefits of demand response and storage against implementation costs. Many storage technologies are still costly and somewhat ineficient, because only 70–85% of stored energy is recoverable. Demand response programs typically do not incur such an eficiency penalty.

What is demand response & energy storage?

Demand response and energy storage are sources of power system flexibility that increase the alignment between renewable energy generation and demand.

Why do power systems use precision timing?

The power system uses precision timing for grid monitoring and situational awareness, to coordinate the operation and integration of a variety of grid assets, and for grid protection and operation. Because power systems are so large and often geographically separated, power data acquisition systems need to share a common time source.

Why is energy storage important in optimisation scheduling research?

Energy storage, as a key means of stabilising fluctuations in clean energy power generation and improving the absorption capacity of a system, has been widely used in optimisation scheduling research.

What is a multi-storage integrated energy system?

To address the insufficient flexibility of multi-energy coupling in the integrated energy system and the overall strategic demand of low-carbon development, a multi-storage integrated energy system architecture that includes electric storage, heat storage and hydrogen storage is established.

How are energy supply priority weight values assigned to different energy storage units?

According to the carbon emission cost of various energy sources, different energy supply priority weight values are assigned to various energy storage units according to the carbon emission cost. The hierarchical energy supply control strategy is shown in Fig. 2: Hierarchical energy supply control strategy.
