All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of a control method of a charging station energy management system according to an embodiment of the present invention.
In one embodiment of the present invention, as shown in fig. 2, the charging station energy management system may include: the energy management system comprises an energy management host and a plurality of energy management sub-controllers in communication connection with the energy management host, wherein the energy management sub-controllers are respectively used for receiving state information of electric equipment, for example, the number of the energy management sub-controllers is n, and the number of the electric equipment is n.
Specifically, the energy management host is in communication with the energy management sub-controller, and is responsible for collecting information of each energy management sub-controller, processing requests of each energy management sub-controller, and issuing energy distribution instructions to each energy management sub-controller for controlling the electric equipment to use, and meanwhile, the energy management host is connected with the energy storage equipment (or photovoltaic equipment) and controls the start-stop operation of the energy storage equipment (or photovoltaic power generation).
The energy management sub-control is respectively communicated with the energy management host and the corresponding electric equipment, and is used for acquiring the energy demand of the electric equipment in real time, reporting the demand parameters to the energy management host, and analyzing and then transmitting the energy management command issued by the energy management host to the electric equipment.
The electric devices are devices that work by using electric power, such as charging piles, energy storage devices, household appliances, and the like.
Photovoltaic equipment is a power generation equipment that directly converts solar radiation energy into electrical energy.
The control method of the charging station energy management system of the present invention is described in detail below.
As shown in fig. 1, a method for controlling an energy management system of a charging station according to an embodiment of the present invention may include the following steps:
and S1, receiving the state information sent by the plurality of energy management sub-controllers through the energy management host.
Wherein, the state information that a plurality of energy branch accuse sent is the state information of corresponding consumer, includes: SOC (State of Charge) information, required power, and buffer allocation ratio. The energy management host receives the state information of the electric equipment sent by the energy management sub-controllers.
It should be noted that the energy management host collects the electricity meter of the whole station metering information and the sensor for collecting the oil temperature of the transformer at the transformer side, and the sensor information mainly includes the temperature information of the transformer and is used for reducing the power operation of the station after the over-temperature of the transformer is detected.
And S2, calculating the energy buffer interval allocated to the current energy management sub-control according to the power information of the charging station and the state information sent by the plurality of energy management sub-controls.
According to one embodiment of the invention, calculating the energy buffer interval allocated to the current energy management branch control according to the power information of the charging station and the state information sent by the plurality of energy management branch controls comprises the following steps: calculating the residual power of the charging station according to the state information sent by the plurality of energy management sub-controllers and the total power of the charging station; and calculating the energy buffer interval of the current energy management sub-control according to the residual power and the power request information sent by the current energy management sub-control.
Further, according to an embodiment of the present invention, the energy buffer interval of the current sub-control of energy management is calculated by the following formula:
W m ＝(100-soc)*B+N p (1)
wherein, W m Representing an upper limit value of an energy buffer interval of the current energy management sub-control, soc representing charge state information of electric equipment corresponding to the current energy management sub-control, B representing a buffer distribution proportion of the electric equipment corresponding to the current energy management sub-control, N p And the required power of the electric equipment corresponding to the current energy management sub-control is represented.
Specifically, a total power M of the charging station is obtained, and a total power N already allocated to the upper limit values of all energy buffer intervals of the energy management sub-control is obtained, so that the remaining allocable power Q of the charging station is M-N. And calculating an upper limit value Wm of the energy management module buffer interval according to the SOC information, the required power information Np and the current buffer allocation proportion B of the electric equipment reported by the requested energy management sub-control, for example, calculating and obtaining the upper limit value of the energy buffer interval of the current energy management sub-control through the formula (1). The lower limit value of the energy buffer interval is 0. Therefore, the energy buffer interval of the current energy management sub-control is 0-Wm.
Further, according to an embodiment of the present invention, an upper limit value of an energy buffer interval of a last current energy management sub-control is obtained; calculating the difference value between the upper limit value of the energy buffer interval of the current energy management sub-control and the upper limit value of the energy buffer interval of the last current energy management sub-control; when the difference value is smaller than the residual power, sending the energy buffer interval of the current energy management sub-control to the current energy management sub-control; and when the difference value is larger than or equal to the residual power, taking the energy buffer interval of the last current energy management sub-control as the energy buffer interval of the current energy management sub-control.
That is, if the difference between the upper limit value of the energy buffer interval of the current energy management sub-control and the upper limit value of the energy buffer interval of the last current energy management sub-control is greater than the remaining power, the energy buffer interval is not allocated to the current energy management sub-control, and the upper limit value of the last energy buffer interval is directly used as the upper limit value of the current energy buffer interval.
And S3, sending the energy buffer interval to the current energy management sub-controller through the energy management host.
And S4, when the required power of the current electric equipment is in the energy buffer interval corresponding to the energy management sub-control, controlling the output power of the current energy management sub-control to be the required power.
According to one embodiment of the invention, when the required power of the electric equipment is greater than the upper limit value of the energy buffer interval of the current energy management sub-control, the output power of the current energy management sub-control is controlled to be the upper limit value of the energy buffer interval of the current energy management sub-control.
Specifically, whether a power-up request (required power) of the electric equipment is received by the current energy management sub-control is judged, if so, whether the required power of the electric equipment is in an energy buffer interval of the energy management sub-control is judged, and if so, the output power of the current energy management sub-control is directly controlled to be the required power of the electric equipment so as to supply power to the electric equipment; and if not, taking the upper limit value of the energy buffer area of the current energy management sub-control as output power to supply power to the electric equipment. According to one embodiment of the invention, when the required power of the current electric equipment is the reduced power requirement, the output power of the current energy management sub-control is controlled to be the required power.
That is to say, when the current electric device needs to reduce power, it is not necessary to determine whether the required power is in the energy buffer interval of the corresponding energy management sub-control, and the current energy management sub-control is directly controlled to output the required power so as to control the corresponding electric device to reduce power.
Further, according to an embodiment of the present invention, when the demanded power of the current electric device is a reduced power demand, or when the demanded power of the electric device is greater than an upper limit value of the energy buffer interval of the current energy management sub-control, the method further includes: and updating the state information of the current electric equipment to control the energy management host to update the energy buffer interval corresponding to the energy management sub-control.
That is to say, after the execution of the current control logic is completed, the updated state information of the electric device needs to be sent to the corresponding energy management sub-controller, and then the updated state information of the electric device is sent to the energy management host by the energy management sub-controller to be stored correspondingly, so as to facilitate the next use.
In order to reduce energy consumption and achieve the purpose of turning on an energy storage device (photovoltaic device) in advance according to the operation condition of the system to prevent the occurrence of insufficient power, in an embodiment of the present invention, the control method of the energy management system of the charging station further includes: acquiring the current operation condition of the system; and determining whether to control the energy storage equipment to be in an open state or not according to the current running condition. Wherein, the operation condition of the system comprises: the total power of the currently allocated energy buffer interval, the total power of the current charging station, the total power of the allocated energy buffer interval at the previous moment and the total power of the charging station at the previous moment.
Further, determining whether to control the energy storage device to be in an on state according to the current operating condition includes: acquiring the total power of the currently allocated energy buffer interval and acquiring the total power of the current charging station; acquiring the total power of the energy buffer interval allocated at the previous moment, and acquiring the total power of the charging station at the previous moment; calculating the change rate of the total allocable power of the remaining power according to the total power of the currently allocated energy source buffer interval, the total power of the current charging station, the total power of the previously allocated energy source buffer interval and the total power of the charging station at the previous moment; and when the change rate is greater than the preset value, controlling the energy storage equipment to be in an opening state. The preset value may be calibrated according to actual conditions, for example, the preset value may be 300.
For example, the total remaining power allocable power change rate may be calculated by the following formula:
wherein, X represents the change rate of the total remaining power allocable power, M 'represents the total power of the allocated energy source buffer interval at the previous moment, N' represents the total power of the charging station at the previous moment, M represents the total power of the current charging station, N represents the total power of the currently allocated energy source buffer interval, and t represents the time interval.
Specifically, assuming that the time interval t is 1min, then the total power N of the currently allocated energy source buffer interval, the total power M of the current charging station, the total power N 'of the allocated energy source buffer interval before 1 minute, and the total power M' of the charging station before 1 minute are obtained, and the total remaining allocable power change rate X is calculated by the above formula (2). When X is larger than a preset value (such as 300), the required power of the charging station is increased quickly, and the energy storage device or the photovoltaic device needs to be started, so that insufficient power supply is avoided.
The control method of the invention is respectively described below for the energy management host, the energy management sub-control and the power utilization equipment.
