The optimal energy storage capacity configuration obtained in a specific year is lacking in large-scale, multi-technical applications and medium- and long-term capacity optimization models.
The continuous discharge time of energy storage under rated conditions is a key factor in determining the power capacity of energy storage. The size of the transmission capacity directly affects one of the important factors of the energy storage capacity at the supply end.
The proposed model provides quantitative decision-making guidance for formulating a country's energy storage technology selection and capacity allocation schemes.
The annual energy storage capacity planning is determined by synthesizing the energy output of all time slices. It is also a common and mature method in power planning models and is sufficient for the proposed model based on its application in similar models.
Parameter setting The model parameters are divided into energy storage, power generation, and others. Energy storage-related parameters mainly involve costs, performance, and other aspects. Examples include continuous discharge time, self-discharge rate, charging and discharging efficiency, and upper and lower limits of the charge state.
To improve the utilization of RE and reduce wind and solar power curtailment, China has issued a series of energy storage policies at the national and provincial levels to promote the high-quality and large-scale development of energy storage (National Energy Administration).
