The embodiment of the application provides an optical storage charging power scheduling method which is applied to an optical storage charging system, wherein the optical storage charging system comprises a photovoltaic module, an energy storage module and a charging module, the charging module comprises a plurality of charging piles, the optical storage charging system is integrated into a public power grid, and the method is used for performing power scheduling on an electricity utilization module in the optical storage charging system so as to avoid the condition of super-power operation. The execution body of the embodiment of the application is electronic equipment, such as a server, a desktop computer, a notebook computer, a tablet computer and other electronic equipment which can be used for carrying out power scheduling on the optical storage and charging system.
As shown in fig. 2, a flow chart of an optical storage and charging power scheduling method according to an embodiment of the present application is shown, where the method includes:
Taking a public light storage charging point station of an electric automobile as an example, the electric load is electric equipment except a charging pile in the power station, such as an illuminating lamp and the like.
It should be noted that, at present, in order to avoid the overpower operation of the optical storage and charging system, the power of each charging pile in the charging module is often selected to be reduced, and if the use power of the charging pile is limited, the impact of the starting of the charging pile cannot be avoided, so that the safety of the optical storage and charging system and the power grid cannot be ensured, the output power of the charging pile is reduced, and in order to solve the problem, in the embodiment of the application, the power adjustment object is selected according to the total power supply amount of the system and the power requirements of the power load power, the power of the energy storage module and the power characterization of the charging module. The power regulation object can be an energy storage module and/or a charging module, since the power of the electric load is not adjustable.
Specifically, in an embodiment, the utility power is denoted as P1, the photovoltaic module power is denoted as P2, the energy storage module power is denoted as P3, the charging module power is denoted as P4, the power consumption load power is denoted as P5, and when the total power supply amount of the system represented by the accumulated result of the utility power and the photovoltaic module power is smaller than the total power consumption requirement represented by the accumulated result of the power consumption load power, the energy storage module power and the charging module power (p1+p2 < p3+p4+p5), but the total power supply amount of the system is not smaller than the sum of the power consumption load power and the charging module power (p1+p2 is greater than or equal to p4+p5), it is determined that the power scheduling object includes the energy storage unit.
When the total system power supply quantity represented by the accumulated result of the public power grid power and the photovoltaic module power is smaller than the total power consumption requirement (P1+P2 < P3+P4+P5) represented by the accumulated result of the electric load power, the energy storage module power and the charging module power, and the total system power supply quantity is smaller than the sum (P1+P2 < P4+P5) of the electric load power and the charging module power, determining that the scheduling object comprises the charging module, and at the moment, even if the energy storage module has the charging requirement, prohibiting the energy storage module from being charged.
When the total power supply quantity of the system represented by the accumulated result of the public power grid power and the photovoltaic module power is not smaller than the sum of the power consumption requirements represented by the power consumption load power, the power of the energy storage module and the power of the charging module (P1+P2 is more than or equal to P3+P4+P5), power scheduling is not needed at this time, each charging pile in the charging module can be normally started, and the energy storage system can be normally charged if the charging requirements exist.
In step 203, when the power scheduling object includes a charging module and the energy storage module has a discharging condition, a system electric quantity output threshold is determined according to the photovoltaic module power, the energy storage module power and the public power grid power.
Whether the energy storage module has a discharge condition or not can be determined according to the capacity of the energy storage unit, for example, when the current capacity of the energy storage module reaches a preset capacity threshold, it is determined that the energy storage module has a discharge condition.
Specifically, when the power scheduling object includes a charging module and the energy storage module has a discharging condition, the accumulated result of the photovoltaic module power, the energy storage module power and the public power grid power can be determined as a system electric quantity output threshold.
And 204, determining the target power of each charging pile in the charging module according to the system electric quantity output threshold and the power consumption load power, and carrying out power scheduling on the charging module according to the target power.
Specifically, the difference between the system electric quantity output threshold and the power of the electric load can be determined as the target power of each charging pile in the charging module, and then the charging module is subjected to corresponding power scheduling according to the target power.
Specifically, in an embodiment, when the power scheduling object includes a charging module and the energy storage module does not have a discharging condition, determining the total power supply amount of the system as a system power output threshold; and determining the difference between the system electric quantity output threshold value and the electric load power as the target power (P4=P1+P2-P5) of each charging pile in the charging module.
Specifically, when the energy storage module does not have a discharging condition, it can be determined that the energy storage module cannot be used as a power supply end of the charging module, so that the total system power supply quantity represented by the accumulated result of the public power grid power and the photovoltaic module power is used as a system power quantity output threshold.
On the basis of the above embodiment, as a practical manner, in an embodiment, determining the target power of each charging pile in the charging module according to the system power output threshold and the electric load power includes:
step 2041, if the system electric quantity output threshold is not less than the sum of the power of the charging module and the power of the electric load (P1+P2+P3 is greater than or equal to P4+P5), determining that the target power of each charging pile in the charging module is the rated power of each charging pile;
in step 2042, if the system power output threshold is smaller than the sum of the power of the charging module and the power of the power load (p1+p2+p3 < p4+p5), the target power of each charging pile in the charging module is determined to be the difference between the system power output threshold and the power load (p4=p1+p2+p3-P5).
When the energy storage module is determined to be in the preset discharging time period, the energy storage module is preferentially used for supplying power to the charging module, when the electric quantity of the energy storage module is insufficient, the energy storage module is used for supplying power to the charging module based on the public power grid, and when the energy storage module is used for supplying power to the charging module based on the public power grid, the public power grid outputs power P1=P4+P5-P3-P2.
Specifically, when p1+p2+p3 is greater than or equal to p4+p5, the charging module is started normally, i.e. the target power of each charging pile is the rated power of each charging pile. Under the condition that P1+P2+P3 is less than P4+P5, the charging module is started in a power-limited mode, and the target power P4=P1+P2+P3-P5 of the charging module is obtained.
Specifically, in an embodiment, it may be determined whether the energy storage module is in a preset discharge period; when the energy storage module is in a preset discharging time period, the energy storage module is used for supplying power to the charging module preferentially, and when the electric quantity of the energy storage module is insufficient, the energy storage module is used for supplying power to the charging module based on a public power grid; the output power of the public power grid is the difference between the sum of the power of the charging module and the power of the electric load and the sum of the power of the photovoltaic module and the power of the energy storage module, namely P1=P4+P5-P3-P2.
When the energy storage module is not in a preset discharging time period, the power supply for the charging module is preferentially based on the public power grid, and when the electric quantity of the public power grid is insufficient, the power supply for the charging module is based on the energy storage module; the output power of the energy storage module is the difference between the sum of the power of the charging module and the power of the electric load and the sum of the power of the photovoltaic module and the power of the public power grid, namely P3=P4+P5-P1-P2.
It should be noted that, the energy storage unit utilizes the peak-valley electricity price difference to absorb low-price valley electricity and flat electricity, and releases electric energy when electricity consumption is high, so as to reduce electricity consumption cost, and the preset discharging time period of the energy storage unit is the electricity consumption peak time period. The energy storage module is not in a preset discharging time period, and directly supplies power to the charging module based on the public power grid, so that the consumption of charging and discharging resources of the energy storage module is reduced, and the running cost of the optical storage charging system is reduced to a certain extent.
