Virtual energy storage and flexible load

Is a virtual energy storage system cost-effective?

This paper forms a Virtual Energy Storage System (VESS) and validates that VESS is a cost-effective way to provide the function of energy storage through the utilization of the present network assets represented by flexible demand.

Is flexible load a 'virtual energy storage'?

In this sense, flexible load can be regarded as "virtual energy storage". When the newly adjusted load with flexible load is smaller than the original load, it can be suggested that the generation is reduced, which corresponds to the discharging mode of the newly added " virtual energy storage".

What are the benefits of flexible load?

In both typical industrial and residential load scenarios, flexible load reduces integrated costs, increases renewable energy consumption, lowers peak thermal power generation, and decreases the requirement for a battery energy storage system (BESS).

How aggregated demand response (Dr) can act as virtual energy storage?

Aggregated Demand Response (DR) can act as virtual energy storage because DR can provide functions similar to the energy storage by intelligently managing the power and energy consumption of loads. By utilizing the existing network assets, DR can be deployed at scale with lower cost.

What is flexible load?

Flexible load is innovatively categorized as a symmetrical source-type load and decouples power demand with energy consumption. The characteristics, impacts, and feasible operation ranges of the flexible load are further explored.

What is energy storage system (ESS)?

A low inertia power system will encounter more severe frequency stability issues in cases of sudden changes in supply or demand . Therefore, faster response to frequency changes is required. Energy Storage System (ESS) is one solution to facilitate the integration of RES by immediately varying the stored energy.
