Day-ahead Spatio-Temporal Interaction Method of Electric Vehicles, Aggregators and Distribution Network for Photovoltaic Accommodation
Aiming at the issue of utilizing the mobile energy storage characteristics of electric vehicles (EVs) to achieve multi-spatio-temporal load balancing and efficient photovoltaic accommodation in the distribution network
this paper proposes a day-ahead interaction method among EVs
the electric vehicle aggregator (EVA)
and the distribution network. First
a day-ahead interactive operation framework for EVs
EVA
and the distribution network operator (DNO) considering the spatio-temporal characteristics of EVs is established. Considering the economic cost-loss model of battery charging or discharging per unit of energy at different discharge depths
this paper constructs a bi-level interactive model integrating a time-of-use price optimization model based on differentiated load characteristics of feeders for a DNO and an embedded EVA scheduling model. In the model
DNO optimizes the differentiated time-of-use electricity price of each feeder to maximize its revenue on the premise of considering the maximum power constraint of the distribution network. EVA optimizes the charging and discharging schedule of EVs to maximize the sum of EV charging and discharging revenue and the peak regulation subsidy given by the distribution network. Then
the discharging threshold constraint is transformed into a linear constraint
and a solving method based on the sample boundary compression algorithm and CPLEX solver is proposed. Finally
the effectiveness of the proposed model and method is verified through the case simulation.
