This paper proposes a comprehensive life cycle allocation model for energy storage in new energy parks with the aim of enhancing both the economy and accuracy of energy storage allocation. Firstly, a comprehensive operational cost model spanning the entire life cycle of energy storage in new energy park configuration is formulated and energy storage is strategically configured within the park to minimize the overall operational costs. Secondly, we develop a model for calculating incremental costs that accounts for the degradation of available storage capacity. This model incorporates the lifespan attenuation of energy storage, calculated by aggregating equivalent cycle times during actual operation. By regularly updating storage capacity, we compute the incremental costs over the entire lifecycle. An illustrative example demonstrates that our proposed energy storage configuration model not only enhances the utilization of new energy generation within the park but also effectively lowers operational expenses.

摘要

This paper proposes a comprehensive life cycle allocation model for energy storage in new energy parks with the aim of enhancing both the economy and accuracy of energy storage allocation. Firstly, a comprehensive operational cost model spanning the entire life cycle of energy storage in new energy park configuration is formulated and energy storage is strategically configured within the park to minimize the overall operational costs. Secondly, we develop a model for calculating incremental costs that accounts for the degradation of available storage capacity. This model incorporates the lifespan attenuation of energy storage, calculated by aggregating equivalent cycle times during actual operation. By regularly updating storage capacity, we compute the incremental costs over the entire lifecycle. An illustrative example demonstrates that our proposed energy storage configuration model not only enhances the utilization of new energy generation within the park but also effectively lowers operational expenses.
