6 FAQs about [Analysis of the benefits and profits of energy storage plants]
How are energy storage benefits calculated?
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.
Why do new energy power plants need energy storage?
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.
Which energy storage mode is best for new energy plants?
