First, energy storage configuration models for each mode are developed, and the actual benefits are calculated from technical, economic, environmental, and social perspectives. Then, the CRITIC method is applied to determine the weights of benefit indicators, and the TOPSIS method is used to rank the overall benefits of each mode.
This paper proposes a benefit evaluation method for self-built, leased, and shared energy storage modes in renewable energy power plants. First, energy storage configuration models for each mode are developed, and the actual benefits are calculated from technical, economic, environmental, and social perspectives.
Although ESS bring a diverse range of benefits to utilities and customers, realizing the wide-scale adoption of energy storage necessitates evaluating the costs and benefits of ESS in a comprehensive and systematic manner. Such an evaluation is especially important for emerging energy storage technologies such as BESS.
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.
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.
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.
