How much storage capacity should a new energy project have?
For 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.
Can energy storage configuration schemes be tailored for new energy power plants?
This paper proposes tailored energy storage configuration schemes for new energy power plants based on these three commercial modes.
Why do new energy power plants need energy storage?
Due to the uncertainty in the output of new energy power plants, there is a phenomenon of power curtailment during actual output. 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.
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 is energy storage configuration important?
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.
How are the benefits generated by energy storage configuration models evaluated?
In this section, based on the energy storage configuration results mentioned above, the actual benefits generated by these three commercial models are evaluated from four perspectives: technical, economic, environmental, and social. The specific descriptions of the evaluation indicators are as follows.
