Research on Electric Vehicle Charge and Discharge Dispatching Strategy Considering the Demand on Both Sides of Supply and Demand

Description

At present, many scholars at home and abroad have studied the charging and discharging scheduling strategy of electric vehicles considering the demand of both sides and reached various conclusions. The uncoordinated charging of a large number of electric vehicles (EVs) can lead to large spikes in peak loads, which further affect the operation of the power system. Therefore, a micro-grid EV charging coordinated scheduling method is proposed in this study to transfer the load demand from peak to trough. This method selects EV charging mode based on charging urgency index, which can reflect different charging requirements. Then, a coordinated charging scheduling optimization model was established to minimize the overall peak-valley load difference. Various limitations of slow charging electric vehicles, fast charging electric vehicles and microgrid operation are considered.
