Abstract

The invention discloses an electric vehicle charging station with an energy storage system. The charging station adopts a dual power supply mode so that power supply stability is increased. Through an electric energy adjusting effect of the energy storage system of the charging station, a starting-up and shut-down frequency of a conventional generator set and a rotation standby capacity in a power grid can be reduced so that a power grid load curve is stable as far as possible. A large load and a high time-of-use power price of the charging station in the power grid can be reduced, a high power price is avoided, charging station operation cost is reduced, reliability of charging power supply can be increased, and the charging station is ensured to provide the charging power supply for an electric vehicle continuously. Through a bidirectional converter, a condition that the charging station sells power to the power grid becomes possible, an electric energy instruction can be increased and a current fluctuation is reduced, and a power factor is well controlled.

Description

technical field [0001] The invention relates to an electric vehicle charging station with an energy storage system, in particular to a substation capable of adjusting the load of a power grid and having greater economic operation benefits. Background technique [0002] With the development of electric vehicles, the demand for electric vehicle charging stations will also gradually increase, which will lead to an increase in the transient variable of power load demand. In order to alleviate the problem of instantaneous increase in power demand, it can However, it will inevitably lead to an increase in the cost of power construction, and it will lead to the idleness of power resources and power equipment during the charging of non-electric vehicles. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and to invent an electric vehicle charging station, which can effectively relieve the pressure on the power s...
