Shared Energy Storage Capacity Configuration Strategy and Economic Evaluation Method Considering New Energy Consumption

Due to the insufficient consumption capacity of the centralized area of the new energy resources (NER) plant, a shared energy storage system (SESS) optimization configuration strategy and economic evaluation method considering the consumption of NER is proposed. Firstly, a SESS business model for the joint construction and operation of a NER plant based on the current market environment for energy storage systems is proposed. This model can effectively promote NER to participate in SESS transactions and improve the profits of the SESS plant. Secondly, based on the planned active outpower and actual output active power of the NER plant, a shared energy storage system configuration method considering NER consumption is proposed to reduce the abandonment rate of the NER plant. Then, an economic evaluation method considering the lifecycle cost of SESS is proposed. Finally, five NER plants were applied to verify the effectiveness of the proposed SESS capacity configuration strategy and economic evaluation method. The results indicate that the configuration of SESS in NER plants can achieve greater benefits.
