Load characteristics analysis and countermeasures of distributed photovoltaic and electric vehicle connected to Bengbu distribution network
This paper studies the load characteristics and countermeasures of distributed photovoltaic(pv) and electric vehicle connected to Bengbu distribution network. Firstly, the output model of distributed pv and the load model of electric vehicle are established. Then, combining with the target in Bengbu forecast data of the distribution network, distributed pv and electric vehicles were analyzed at the same time, access to Bengbu overall load characteristic and the typical area, The results show that the main reason for the peak-valley difference of the daily load in summer and winter in the target year of Bengbu city is that the distributed pv cannot be completely absorbed in commercial and residential areas during 06:00~10:00, and the load of electric vehicle and distribution network load in residential areas is "adding peak to peak" at night. Based on the above analysis, V2G control strategy combined with time-sharing electricity price policy is proposed to deal with the negative impact brought by distributed pv and electric vehicle access.
