Embodiment

[0180] consider as image 3 In the office park microgrid shown, the basic load in the park is mainly the office building load, and the peak load in summer is about 600kW, which occurs between 8:00-11:00. According to the implementation manner described above, the energy management of the microgrid is performed on a typical summer day, and the scheduling results of the whole day are simulated.

[0181] On the day before the dispatch day, the energy management system executes the day-ahead plan (with a time granularity of 15 minutes) according to the load and photovoltaic forecast results and the electric vehicle charging reservation information, and optimizes the charging and discharging of each electric vehicle's charging plan and energy storage. The electric vehicle charging appointment information is shown in Table 1, and the obtained day-ahead plan is as follows: Figure 4 shown. The energy storage system chooses to charge during the valley period and discharge during the...

Abstract

The invention discloses an energy management method suitable for a micro-grid containing an electric vehicle charging pile. According to the method, an electric vehicle needs to reserve a charging pile before charging, and charging demand information is submitted; on the day before the dispatching day, based on day-ahead prediction data and day-ahead electric vehicle charging reservation information of load and renewable energy power generation, an electric vehicle ordered charging plan and an energy storage charging and discharging plan of each time period of the whole day are made by taking the minimum operation cost and the minimum maximum demand of the micro-grid as targets; in each time period of a dispatching day, based on real-time data of load and renewable energy power generation, optimization is carried out by taking the minimum deviation between energy storage real-time charging and discharging power and a day-ahead energy storage charging and discharging plan as a target; and the day-ahead plan is updated in real time based on the latest information according to the condition of the electric vehicle. Compared with the prior art, the strategy has the advantages of being stable, efficient, economical, environmentally friendly, capable of fully utilizing the flexibility of the electric vehicle, capable of being win-win all aspects and the like.

Description

technical field [0001] The invention belongs to the field of micro-grid energy scheduling, simulation and analysis, and in particular relates to an energy management method suitable for a micro-grid containing electric vehicle charging piles. Background technique [0002] A microgrid is a system that integrates distributed energy sources, energy storage systems, and flexible loads. In recent years, microgrids have been widely used in industrial and commercial buildings because of their characteristics of helping to improve the reliability of local power supply, reduce electricity costs and promote the consumption of renewable energy. [0003] Under the green and low-carbon trend, electric vehicles have become a new type of transportation that governments of all countries are vigorously supporting and developing, and their ownership is growing rapidly. It is estimated that by 2025, the sales of new energy vehicles in China will reach about 20% of the total sales of new vehic...
