Learn MoreEnergy storage systems play a major role in smoothing the fluctuation of new energy output power, improving new energy consumption, reducing the deviation of the power generation plan, and improving the safe operation stability of the power grid. Specific classification scenarios are shown in Figure 4.
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.
Despite the extensive research on energy storage configuration models, most studies focus on a single mode (such as self-built, leased, or shared storage), without conducting a comprehensive analysis of all three modes to determine which provides the best benefits for new energy plants.
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:
By configuring energy storage, new energy power plants can store the excess energy and discharge it when the output is insufficient, thus compensating for the power deficit. Social benefits are defined as the reduction in power curtailment of the new energy power plant after configuring energy storage.
The evaluation of energy storage systems is a complex task that requires the consideration of various indicators and factors. Research in this field has focused on the electricity market and incentive policies, aiming to evaluate the economic benefits of energy storage.
