DETAILED DESCRIPTION

[0019] With reference to the drawings and embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0020] In order to make the objects, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in detail below with reference to the drawings.

[0021] In a first aspect, the embodiments of the present application provide an energy management method.

[0022] In an embodiment, with reference to Figure 1 , Figure 1 The flowchart of an embodiment of the energy management method of the present application is shown in FIG. 1. As shown in FIG. 1, the energy management method comprises the following steps. Figure 1 Step S10, calculating the power consumption of a preset area based on the real-time voltage and the real-time current of the power grid of the preset area; In this embodiment, the real-time voltage and the real-time current of the power grid of the preset area are collected, and the real-time voltage of the power grid of the preset area is multiplied by the real-time current to obtain the product as the power consumption of the preset area.

[0023] Step S20, calculating the electric energy generated by the photovoltaic panel based on the total area of the photovoltaic panel, the solar radiation intensity and the output power of the photovoltaic panel; In some specific embodiments, step S20 comprises: Step S201, calculating the power generation efficiency of the photovoltaic panel based on the total area of the photovoltaic panel, the solar radiation intensity and the output power of the photovoltaic panel; Step S202, calculating the electric energy generated by the photovoltaic panel based on the power generation efficiency, the total area of the photovoltaic panel and the solar radiation intensity.

[0024] In some specific embodiments, step S202 comprises: The product of the power generation efficiency multiplied by the total area of the photovoltaic panel and then multiplied by the solar radiation intensity is obtained as the electric energy generated by the photovoltaic panel.

[0025] In this embodiment, the total area of the photovoltaic panel, the solar radiation intensity, the output power of the photovoltaic panel and the total area of the photovoltaic panel are obtained. It should be noted that the collection period of the solar radiation intensity, the collection period of the output power of the photovoltaic panel, the collection period of the real-time voltage and the collection period of the real-time current are the same, and the number of collections is the same. The area of the photovoltaic panel is obtained based on the parameters at the time of manufacturing, the light intensity is obtained based on the meteorological data, and the output power of the photovoltaic panel is obtained based on the parameters at the time of design. ​

[0026] The total area of the photovoltaic panel, the solar radiation intensity, and the photovoltaic panel output power are substituted into the first preset formula to calculate the power generation efficiency of the photovoltaic panel. The first preset formula is as follows:

[0027] In the formula, represents the power generation efficiency of the photovoltaic panel, represents the photovoltaic panel output power, represents the total area of the photovoltaic panel, represents the solar radiation intensity.

[0028] The power generation efficiency of the photovoltaic panel, the total area of the photovoltaic panel, and the solar radiation intensity are substituted into the second preset formula to calculate the electric energy generated by the photovoltaic panel. The second preset formula is as follows:

[0029] In the formula, represents the electric energy generated by the photovoltaic panel.

[0030] In step S30, the electric energy and the power consumption are compared to obtain a comparison result. In this embodiment, after the power consumption of the preset area and the electric energy generated by the photovoltaic panel are calculated, the power consumption of the preset area and the electric energy generated by the photovoltaic panel are compared to obtain a comparison result, so as to determine whether the electric energy generated by the photovoltaic panel meets the power consumption demand of the preset area based on the comparison result.

[0031] In step S40, a corresponding electric energy scheduling strategy is determined based on the comparison result.

[0032] In some specific embodiments, step S40 includes: When the comparison result is that the electric energy is greater than the power consumption, the first difference value is obtained by subtracting the power consumption from the electric energy. The electric energy corresponding to the first difference value is stored, and the remaining electric energy is transmitted to the preset area.

[0033] In this embodiment, when the comparison result is that the electric energy generated by the photovoltaic panel is greater than the power consumption of the preset area, it is determined that the electric energy generated by the photovoltaic panel can meet the power consumption demand of the preset area, and there is excess electric energy. At this time, the first difference value is obtained by subtracting the power consumption of the preset area from the electric energy generated by the photovoltaic panel, and the first difference value is the size of the excess electric energy. Therefore, the electric energy corresponding to the first difference value generated by the photovoltaic panel is stored for subsequent use during the night or power failure. The remaining electric energy generated by the photovoltaic panel except for the electric energy corresponding to the first difference value is transmitted to the preset area as the electric energy required by the electrical appliances in the preset area, so that the preset area can meet the power consumption demand without purchasing electric energy from the power grid, thereby greatly reducing the power consumption cost of the preset area.

[0034] In some specific embodiments, the step S40 further comprises: when the comparison result is that the electric energy is less than or equal to the power consumption, obtaining a second difference value by subtracting the electric energy from the power consumption; sending the electric energy corresponding to the second difference value to a terminal device, and delivering the electric energy to the preset area.

[0035] In the embodiment, when the comparison result is that the electric energy generated by the photovoltaic panel is less than or equal to the power consumption of the preset area, it is determined that the electric energy generated by the photovoltaic panel cannot meet the power consumption demand of the preset area, and at this time, the electric energy needs to be purchased from the power grid. Therefore, a second difference value is obtained by subtracting the electric energy generated by the photovoltaic panel from the power consumption of the preset area. The electric energy corresponding to the second difference value is sent to a terminal device, so that relevant personnel can determine the size of the electric energy that needs to be purchased from the power grid.

[0036] Further, the electric energy generated by the photovoltaic panel is delivered to the preset area in its entirety, so that the electric energy purchased from the power grid in combination with the electric energy generated by the photovoltaic panel can meet the power consumption demand of the preset area. The electric energy generated by the photovoltaic panel is directly delivered to the preset area in its entirety for use, instead of being stored first and then put into use when the energy storage system is full. This greatly avoids the loss of the electric energy in the process of storage, and solves the technical problem of waste of the electric energy generated by the photovoltaic power generation system in the prior art.

[0037] In the embodiment, the power consumption of the preset area is calculated based on the real-time voltage and the real-time current of the power grid of the preset area. The electric energy generated by the photovoltaic panel is calculated based on the total area of the photovoltaic panel, the solar radiation intensity, and the output power of the photovoltaic panel. The electric energy and the power consumption are compared to obtain a comparison result. Based on the comparison result, a corresponding electric energy scheduling strategy is determined. Through the embodiment, based on the comparison result of the power consumption of the preset area and the electric energy generated by the photovoltaic panel, a corresponding electric energy scheduling strategy is adopted. When the light is sufficient, the electric energy generated by the photovoltaic panel can meet the power consumption demand of the preset area, and there is no need to purchase electric energy from the power grid, which greatly reduces the high power consumption cost of the preset area. When the light is insufficient, the electric energy generated by the photovoltaic panel is delivered to the preset area in its entirety, and the electric energy that needs to be purchased from the power grid is determined. This not only avoids insufficient or excessive electric energy purchased from the power grid, but also avoids the loss of the electric energy in the process of storage, solves the technical problems of waste of electric energy and high power consumption cost of the preset area in the related art.
