How do energy storage stations work?

In this mode, new energy power plants form a consortium to jointly invest in and build an energy storage station. Once the energy storage station is constructed, it operates as an independent entity, serving multiple new energy power plants that participated in the investment.

What constraints must the energy storage station satisfy?

The constraints that the energy storage station must satisfy include the capacity and power constraints of the energy storage configuration, as well as the constraint on the unit cost of the energy storage service. The capacity and power constraints are shown in Eqs. (10 – 11). The unit cost constraint of the energy storage service is as follows:

What are the different types of energy storage configurations?

New energy power plants can implement energy storage configurations through commercial modes such as self-built, leased, and shared. In these three modes, the entities involved can be classified into two categories: the actual owner of the energy storage and the user of the energy storage.

What happens if a power plant withdraws from a consortium?

There is no scenario in which a single plant independently changes the storage strategy or withdraws from the consortium. In this mode, new energy power plants form a consortium to jointly invest in and build an energy storage station.

What is a stationary battery energy storage (BES) facility?

A stationary Battery Energy Storage (BES) facility consists of the battery itself, a Power Conversion System (PCS) to convert alternating current (AC) to direct current (DC), as necessary, and the “balance of plant” (BOP, not pictured) necessary to support and operate the system. The lithium-ion BES depicted in Error!

What are energy storage configuration models?

Energy storage configuration models were developed for different modes, including self-built, leased, and shared options. Each mode has its own tailored energy storage configuration strategy, providing theoretical support for energy storage planning in various commercial contexts.
