*6.2. Description of the System*

The basic parameters of the WT, PV and diesel generator equipment in the microgrid system are shown in Table 1. The rated capacity of the configured single battery is 50% of the total installed capacity of PV and WT [30]. Other parameters of the battery are shown in Table 2. In this paper, there are three main types of air pollutants emitted during the operation of diesel generators: CO2, NOx and SO2 [31]. The corresponding emissions and environmental treatment costs are shown in Table 3.





The maximum discharge depth is 80%, and the operation and maintenance cost coefficient is 0.009 \$/kWh [32].
