计及动态电价的光储充站-电动汽车两阶段联合低碳调度OA

There are various sources of carbon emissions in the photovoltaic-storage-charging stations and a lack of coordinated scheduling strategies for different types of electric energy,resulting in the underutilization of low-carbon resources in the station.Therefore,a two-stage low-carbon scheduling strategy for photovoltaic-storage-charging stations and electric vehicles(EVs)considering dynamic electricity prices is proposed.Firstly,the electric energy in the photovoltaic-storage-charging stations is classified according to whether it contains carbon,and the dynamic electricity price based on clean-carbon electricity coordination is formulated to guide the charging and discharging behaviors of EVs.Secondly,the carbon emission in the stations is modeled in detail.The carbon emissions generated by EVs and energy storage discharging and the dynamic changes of their carbon emission intensity are considered,while considering the carbon emission of electricity purchase in the photovoltaic-storage-charging stations.Finally,a station-vehicle two-stage joint low-carbon scheduling model based on the two-region commuting of EVs is established,and the real-time deviation is adjusted for the intra-day fast-charging load and renewable energy fluctuation.Simulation results demonstrate that the proposed strategy can effectively improve the local consumption rate of photovoltaics.Compared with the scheduling in a single photovoltaic-storage-charging station,the cross-regional scheduling of EVs can realize the spatial-temporal transfer of photovoltaics in the stations and further reduce the carbon emission.
