[0080] At present, in the field of power generation, most of the electricity needs to rely on coal-fired power, which is a non-renewable resource, and coal-fired power pollutes the air and also affects the rise in global temperatures. Therefore, it has become a consensus to develop new energy industries and vigorously promote a low-carbon economy.

[0081] In the prior art, in the process of powering the new energy power source, energy storage is often used to store excess energy and release energy when the new energy is not generated or lacks generation.

The first aspect is that when the ratio of power supply to demand is lower than a certain margin, the discharge mode is started, and when the ratio of power supply to demand is higher than a certain ratio, the charging mode is started; in the charging mode, how to record the renewable energy charged into the power; how to record the proportion of renewable energy during the discharge process; finally, a comprehensive energy storage system renewable energy absorption storage index is formed and recorded to clarify the absorption energy of energy storage in the case of large-scale renewable energy development. If the peak is eliminated, re-planning and additional energy storage equipment will be carried out.

[0093] Figure 2The present invention is a flowchart of a system structure for setting energy storage power supply charging control in an energy storage power supply charging and discharging type identification and metering method according to an embodiment of the present invention.

[0094] like Figure 2 As shown, in one or more embodiments, preferably, the system structure for setting the energy storage power supply charging control specifically includes:

[0095] S201, the system structure specifically includes an energy storage main control system, a renewable energy control module, a battery management system, a bidirectional inverter, and a battery;

[0096] S202, renewable energy and non-renewable energy and the energy storage control system constitute a virtual power plant;

[0097] S203, the energy storage main control system sends corresponding energy input information to the renewable energy control module;

[0098] S204, the energy storage main control system is responsible for outputting DC and AC electric energy;

[0099] S205. The bidirectional inverter is used to control the charging and discharging of the battery.

[0100] In an embodiment of the present invention, a system structure for energy storage power supply charging control is set, and the system structure includes an energy storage main control system, a renewable energy control module, a battery management system, a bidirectional inverter and a battery. Among them, the energy storage main control system and renewable energy and non-renewable energy together constitute a virtual power plant. The energy storage main control system is responsible for sending corresponding energy input information to the renewable energy control module and outputting DC and AC electrical energy. The bidirectional inverter plays a key role in the system and is used to control the charging and discharging process of the battery. The design of the entire system structure is aimed at realizing effective management and control of the energy storage power supply to meet different energy needs and power output requirements.

[0101] Figure 3 The present invention is a flowchart of setting the collection of new energy charging and discharging power and the start of charging and discharging control in a method for identifying and measuring the charging and discharging type of an energy storage power supply according to an embodiment of the present invention.

[0102] like Figure 3 As shown, in one or more embodiments, preferably, the setting of collecting the charging and discharging power of new energy and starting the charging and discharging control specifically includes:

[0103] S301, collect information of new energy power sources in real time, and store voltage and current of new energy;

[0104] S302, collecting information on fossil energy voltage in real time, and storing the voltage and current of the fossil energy;

[0105] S303, determining the current real-time total capacity of the standby power load;

[0106] S304, determining whether the first calculation formula is satisfied, if satisfied, performing charging control, otherwise, performing discharging control;

[0107] The first calculation formula is:

[0108] X+H>P

[0109] Among them, P is the total capacity of real-time standby power load, X is the power output of new energy, and H is the power output of fossil energy.

[0110] In the embodiment of the present invention, the collection and control of charging and discharging power of new energy sources: This is a system or process for energy management, which is mainly responsible for collecting the charging and discharging power of new energy sources (such as solar energy, wind energy, etc.) and fossil energy sources (such as coal, oil, natural gas, etc.), and judging and controlling the charging and discharging behavior of energy sources based on the collected data; Real-time information collection of new energy sources, and storage of voltage and current of new energy sources: This is a basic function of the system, which will continuously collect information from new energy sources (such as photovoltaic panels, wind turbines, etc.), especially data about voltage and current, and store these data in the system for subsequent analysis and use; Real-time information collection of fossil energy voltage, and storage of voltage and current of fossil energy sources: Similarly, the system will also collect real-time information on fossil energy sources, including key parameters such as voltage and current, and save these data for energy management and analysis; Determine the current real-time total capacity of standby power load: This step is to understand the power demand of the current system or power grid, that is, the total capacity of the real-time standby power load. This is one of the key factors in determining whether charging or discharging is required; Determine whether the first calculation formula is satisfied, if satisfied, then charge control is performed, otherwise, then discharge control is performed: This is a decision-making process. The system will compare the previously collected data, especially the power output of new energy (X) and the power output of fossil energy (H), with the total capacity of the real-time standby power load (P). If X+H is greater than P, it means that the current energy output can meet the power demand, so the system will control charging; conversely, if X+H is less than P, it means that the energy output is not enough to meet the demand, and the system will control discharging to make up for the shortage of energy supply. In short, this is the basic function and workflow of an energy management system: by collecting the voltage and current information of new energy and fossil energy in real time, judging the current power load demand, and deciding whether to charge or discharge according to a specific calculation formula. Such a system helps to manage and use energy more effectively, especially in the context of the gradual popularization and use of new energy, it can better balance energy supply and demand and improve energy efficiency.

[0111] Figure 4It is a flow chart of setting carbon emission records of a charging process and calculating the total capacity of new energy points in a method for identifying and measuring the charging and discharging types of an energy storage power supply according to an embodiment of the present invention.

[0112] like Figure 4 As shown, in one or more embodiments, preferably, the setting of the carbon emission record of the charging process and the calculation of the total capacity of the new energy credits specifically include:

[0113] S401, calculating the fossil energy injection using a second calculation formula according to the collection of new energy charging and discharging power;

[0114] S402, adjusting the total capacity of new energy credits in real time according to the third calculation formula for the injection of fossil energy;

[0115] The second calculation formula is:

[0116]

[0117] Among them, J is the injection of fossil energy;

[0118] The third calculation formula is:

[0119]

[0120] Among them, SS is the total capacity of new energy points, t is time, and T is the monitoring period.

[0121] In the embodiment of the present invention, in the process of setting the carbon emission record of the charging process and calculating the total capacity of the new energy credits, it is necessary to integrate a variety of data and calculation formulas to ensure the effectiveness and accuracy of energy management. First, set the carbon emission record of the charging process: during the charging process, it is necessary to record and monitor the carbon emissions generated by charging. This can be achieved by installing carbon emission monitoring equipment or using an existing energy management system. These emission data can help evaluate and optimize the environmental protection of the charging process and provide data support for future energy strategies; secondly, calculate the total capacity of new energy credits: the total capacity of new energy credits refers to the total energy provided by new energy (such as solar energy, wind energy, etc.) to the system or power grid over a period of time. By real-time monitoring of the charging and discharging power of new energy, its total credit capacity can be calculated, which helps to evaluate the contribution of new energy and the energy balance state of the system. In the second, the fossil energy injection is calculated according to the collection of the charging and discharging power of new energy using the second calculation formula. The purpose of this is to supplement the energy demand through fossil energy when the supply of new energy is insufficient. Finally, the total capacity of new energy credits is adjusted in real time according to the third calculation formula based on the injection of fossil energy: the factors such as fossil energy injection, new energy charging and discharging power, and the total capacity of the standby power load are considered to adjust the total capacity of new energy credits in real time. This adjustment helps maintain the energy balance and stability of the system. In this solution, a comprehensive and efficient energy management system can be built by integrating carbon emission records, the collection of new energy charging and discharging power, the calculation of fossil energy injection, and the adjustment of the total capacity of new energy points. Such a system can not only ensure the stability and sustainability of energy supply, but also improve energy efficiency and reduce carbon emissions, thereby achieving more environmentally friendly and sustainable energy utilization. In the future, with the continuous development and popularization of new energy technologies, such energy management systems will play a more important role.

[0122] Figure 5 It is a flow chart of recording carbon emissions during a discharge process based on obtaining the total capacity of new energy points in a method for identifying and measuring the charge and discharge types of an energy storage power source according to an embodiment of the present invention.

[0123] like Figure 5 As shown, in one or more embodiments, preferably, the carbon emission record of the discharge process based on the total capacity of the new energy points is specifically performed including:

[0124] S501, calculating the proportion of total carbon released in real time according to the fourth calculation formula;

[0125] S502, calculating the real-time release of new energy energy using the fifth calculation formula according to the real-time release of total carbon content;

[0126] The fourth calculation formula:

[0127] ZB=SS÷DS

[0128] Among them, SS is the total capacity of new energy points, DS is the real-time total battery capacity, and ZB is the real-time proportion of total carbon released;

[0129] The fifth calculation formula is:

[0130]

[0131] Among them, X t In order to release new energy in real time, P t The real-time output power.

[0132] In the embodiment of the present invention, on the basis of obtaining the total capacity of new energy credits, recording the carbon emissions during the discharge process is a key step, which helps us understand and optimize the environmental impact of the entire energy system. Next, we will calculate the real-time carbon release ratio and the real-time release of new energy energy in real time according to the fourth and fifth calculation formulas provided. First, let's look at the fourth calculation formula: ZB = SS ÷ DS, where: ZB represents the real-time carbon release ratio, which is a ratio that represents the proportion of the total capacity of new energy credits to the real-time battery total capacity. SS represents the total capacity of new energy credits, that is, the total energy provided by new energy to the system or power grid over a period of time. DS represents the real-time battery capacity, which represents the total energy that the current battery can store. Through this formula, we can get the real-time carbon release ratio, that is, the proportion of new energy in the entire battery capacity. Next, let's look at the fifth calculation formula: Xt = Pt × ZB, where: Xt represents the real-time release of new energy energy, that is, the energy actually released into the system by new energy at the current moment. Pt represents the real-time output power, that is, the discharge power of the battery at a certain moment. ZB is the real-time carbon release ratio we obtained from the fourth calculation formula. This formula tells us that the real-time release of new energy energy is the product of the real-time output power and the real-time release of the total carbon ratio. Combining the above two formulas, we can understand the release of new energy energy and the corresponding carbon emissions during the discharge process in real time. This provides us with an important reference to help us optimize energy use strategies, reduce carbon emissions, and improve energy efficiency. In summary, by combining key data such as the total capacity of new energy points, the real-time total battery capacity, and the real-time output power, we can use the fourth and fifth calculation formulas to calculate the real-time release of the total carbon ratio and the real-time release of new energy energy, so as to better manage and optimize the energy system, reduce carbon emissions, and promote sustainable development.

[0133] To obtain the real-time output power and determine whether it will exceed the limit, we need to perform the following steps:

[0134] Set a limit value for the energy storage output power, which can be determined based on safety considerations, equipment capabilities or other relevant factors.

[0135] The output power data of the energy storage system is obtained in real time through sensors or corresponding measuring equipment.

[0136] Determine whether the output power obtained in real time exceeds a preset limit value.

[0137] If the real-time output power exceeds the limit value, the timer starts to count and the duration of exceeding the limit is recorded.

[0138] If the real-time output power does not exceed the limit value, the timing is stopped.

[0139] Specifically, obtain the real-time output power and determine whether it will exceed the limit, and record the duration of exceeding the limit.

[0140] Pre-set a limit value for energy storage output power;

[0141] It is determined in real time whether the real-time output power of the energy storage output at the current moment exceeds the limit value of the energy storage output power. If it exceeds, the time is counted and the total over-limit time is recorded.

[0142] Figure 6 The present invention is a flowchart of a method for identifying and measuring the charge and discharge types of an energy storage power source in accordance with an embodiment of the present invention for determining whether energy storage needs to be expanded according to an over-limit duration.

[0143] like Figure 6 As shown, in one or more embodiments, preferably, judging whether to expand energy storage according to the over-limit duration specifically includes:

[0144] S601, obtaining the over-limit duration and the total operating duration of the energy storage;

[0145] S602, calculating the ratio of the over-limit duration to the total operating duration of the energy storage as the over-limit ratio;

[0146] S603: When the over-limit ratio exceeds 80% and the total operating time exceeds the minimum limit value, it is considered that energy storage needs to be expanded.

[0149] S701, displaying discharge carbon emissions according to the carbon emission records of the discharge process, where the display content is the real-time release of new energy;

[0150] S702, displaying the charging carbon emissions according to the carbon emission records of the charging process, and displaying the total capacity of fossil energy injection and new energy points;

[0151] S703: When the energy storage is saturated, the pre-set super capacitor is used to provide additional power.

[0152] In the embodiment of the present invention, to realize the display of the energy storage charging and discharging process and its carbon emission record, and to set the corresponding emission display and the supplementary power supply logic during saturated operation, we can design a simple program to simulate this process. The following is a conceptual code framework that uses Python as the programming language. Please note that in actual applications, these data will come from actual energy storage systems, carbon emission monitoring equipment, and energy management systems. First, we need to define some basic data structures and functions to simulate the charging and discharging process, carbon emission records, and the supplementary power supply logic of supercapacitors. Then define an EnergyStorage class to manage the charging and discharging process of energy storage, record the relevant carbon emissions, and define a SuperCapacitor class to simulate the power supply behavior of supercapacitors. Create an energy storage instance and a supercapacitor instance, and simulate a series of charging and discharging operations. When the energy storage is close to saturation, we use supercapacitors to supplement the power supply. After each operation, we print the current state of the energy storage and the carbon emissions generated during the charging or discharging process. Please note that the calculation of carbon emissions here is very simplified and assumes a fixed carbon emission factor. In actual situations, the carbon emission factor will vary depending on the type of energy used and the efficiency of the energy production process. In addition, for the energy absorption of renewable energy, we assume that the discharge process can absorb the same amount of CO2, which is only a symbolic representation and does not represent the direct carbon capture process in reality.

[0153] You may need to adjust the parameters and logic in the code to more accurately simulate your energy storage system and carbon emissions.
