Description

technical field [0001] The invention relates to the technical field of charging stations, in particular to a system and method for setting a liquid flow electric fuel charging station in a thermal power plant. Background technique [0002] Generally speaking, electric energy cannot be stored (the current battery energy storage cost is high and the energy storage capacity is limited), so the thermal power plant needs to generate as much electricity as the user needs, so as not to cause energy waste. But usually in the power system, the demand load of each thermal power plant is constantly changing. In order to maintain the balance of active power and keep the system frequency stable, the power generation department needs to change the power generation of the generator accordingly to adapt to the change of power load. This is called peak shaving. [0003] In China's three northern regions, the power market capacity is abundant, gas turbines, pumped storage and other peak-adju...
