Abstract [en]

In order to ensure the operation of distributed energy and relieve the pressure of retired EV batteries, repurposing EV batteries in energy storage for second-life use has gained increasing attentions. Considering that distributed battery storages are still not economically attractive at present, the booming of sharing economy may provide a more feasible option. Based on a non-cooperative game theoretical model, this study aims to make the economic analysis on repurposed EV batteries in a distributed PV system under sharing business models. Four scenarios were proposed, including: S1-without battery storage and without shared PV generation, S2-with battery storage and without shared PV generation, S3-with battery storage and with shared PV generation among the same type of users, as well as S4-with battery storage and with shared PV generation among different types of users. S1 is taken as a benchmark case, S2 is regarded as a traditional business model, and both S3 and S4 represent sharing business models. With a case study in Beijing, the obtained results show that: (i) sharing business models of S3 and S4, especially S4-with battery storage and with shared PV generation among different types of users, can reduce electricity expenses of the whole community; (ii) sharing business models, especially S4, can obviously enhance the PV self-consumption ratio, indicating a possible way to relieve government's financial burden of feed in tariff; (iii) sharing business models, especially S4, can also improve the economic viability of retired EV batteries significantly, which can help to promote the second-life use and provide references for setting retired EV batteries' prices.
