Learn MoreFor instance, in Guangdong Province, new energy projects must configure energy storage with a capacity of at least 10% of the installed capacity, with a storage duration of 1 h . However, the selection of the appropriate storage capacity and commercial model is closely tied to the actual benefits of renewable energy power plants.
In the context of increasing renewable energy penetration, energy storage configuration plays a critical role in mitigating output volatility, enhancing absorption rates, and ensuring the stable operation of power systems.
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:
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.
On the other hand, refining the energy storage configuration model by incorporating renewable energy uncertainty management or integrating multiple market transaction systems (such as spot and ancillary service markets) would improve the model's practical applicability.
Energy storage technologies has both the power supply capacity and the power storage capacity, so the power of energy storage technologies includes the supply power and the storage power , and both of them are nonnegative and no more than the installed capacity for any energy storage technology in planning periods of power areas .
