Embodiment 1

[0057] Such as figure 1 As shown in -5, the invention of this example is a large-scale charging station grid frequency control system. The control system includes a charging station information sending and receiving module, a charging station control module, a control strategy output module, and a charging pile information receiving module connected in sequence And a sending module; the charging station information sending and receiving module is respectively connected with the power grid dispatching center and the charging pile information receiving and sending module.

[0058] The charging station information sending and receiving module includes a grid load frequency signal receiving unit and a charging station information feedback unit. The grid load frequency signal receiving unit mainly receives information on the power generation of the grid when the grid load peaks or valleys do not match the load demand, which causes the grid frequency to drop or rise, that is, the grid ...

Abstract

The invention relates to a control system for a grid frequency of a large-scale charging station. The control system comprises a charging station information sending and receiving module, a charging station control module, a control strategy output module and a charging pile information receiving and sending module, wherein the charging station information sending and receiving module is respectively connected with a grid dispatching center and the charging pile information receiving and sending module. According to the system, through large-scale electric automobile participation frequency fluctuation response and according to the condition that charging and discharging power can be utilized by the charging station in real time, electric automobiles in the charging station are arranged orderly for charging and discharging.

Description

Technical field: [0001] The invention relates to a grid frequency control system, and more particularly to a large-scale charging station grid frequency control system. Background technique: [0002] With the development of renewable energy, the requirements for automatic power generation control (AGC) are getting higher and higher, and the rapid development of electric vehicles provides an opportunity for stable operation of the power system. The main role of AGC is to maintain the balance of power generation and load on the grid, but with the influx of sustainable energy, the balance of future grid demand cannot rely solely on traditional energy sources. If electric vehicle battery energy participates in the frequency adjustment of the power system, AGC can respond to frequency fluctuations from the power generation side and the load side at the same time, assisting traditional power stations. There are two main ways for electric vehicles to participate in frequency adjustment...
