Abstract

The invention discloses a district-level charging load regulation and control strategy and method based on model predictive control. The district-level charging load regulation and control strategy comprises the steps of day-ahead strategy making, day-ahead rolling optimization and real-time feedback correction. The district-level charging load regulation and control strategy is divided into an autonomous balance mode and a scheduling response mode; the method aims to solve the problems of prediction errors, randomness and the like in transformer area level load regulation and control, can reduce the three-phase imbalance degree on the premise of ensuring that the power of a transformer area is not out of limit, improves the charging service capability of the transformer area and increases the profit of the transformer area, and has the capability of tracking a superior scheduling curve.

Description

technical field [0001] The invention relates to the field of intelligent power consumption and economic dispatching of electric power systems, in particular to a strategy and method for regulating charging load at the station level based on model predictive control. Background technique [0002] In the current research on orderly charging, it is believed that the charging power of electric vehicles can be completely controlled by the operator or the grid. However, in actual application scenarios, charging power regulation is affected by various factors such as BMS and charging piles. As the basic unit of distribution network management, the station area is the terminal node for users, distributed new energy, energy storage and charging facilities to access the power grid. Through the intelligent regulation and independent balance of the station area, it can provide high-quality services for users such as electric vehicles, realize the local consumption of new energy, improv...
