Commercial operation mode of shared energy storage system considering power transaction satisfaction of renewable energy power plants

Abstract

The sharing economy mode can promote an optimal allocation and utilization of resources, and its integration with the energy storage and renewable energy can improve their utilization rate and reduce the dispatching deviation. In order to reduce the renewable energy dispatching deviation and improve profits of shared energy storage, this paper proposes a shared energy storage commercial operation mode considering the power transaction satisfaction of renewable energy plants. Firstly, in order to promote the participation of renewable energy plants in the commercial mode, a power transaction satisfaction mode is proposed, and a multilateral bidding transaction mode based on power transaction satisfaction is established. Secondly, in order to further compensate the dispatching deviation, a deviation elimination model through jointing multiple shared energy storages and renewable energy plant clusters is established, and the advantages of renting multiple shared energy storages are analyzed. Thirdly, in order to quantify the profits of each participant in the commercial mode, a shared profit and settlement cost model is developed. Finally, the correctness of the above proposed model is verified by analyzing the case study.
