Problems solved by technology

Since building A and building B use their own independent solar power generation systems, the users of building A cannot get enough power, while the users of building B get too much power
This situation cannot realize the reasonable distribution of the power generated by the solar power generation system, and thus cannot meet the actual needs of users.

Embodiment 1

[0051] Please refer to the attached figure 1 , which shows the flow of the method for controlling the use of photovoltaics in multiple buildings provided by Embodiment 1 of the present invention.

[0052] figure 1 The process shown includes:

[0053] S101. Obtain the required power consumption of each building within a unit time period.

[0054] In step S101 , the required power consumption of each building within a unit time period is obtained, and the required power consumption in this step refers to the power that can meet the actual power consumption needs of users in the entire building. In the process of acquisition, a specific acquisition method is: you can check the power consumption of the building in the past unit time period, take the maximum value of the power consumption in the past, and take the maximum value as the total value of the building. power consumption. The unit time period in this step may be one day, may also be a month, and of course may also be ...

Embodiment 2

[0073] Please refer to the attached figure 2 , which shows the flow of the photoelectric usage control method for multiple buildings provided by Embodiment 2 of the present invention.

[0074] figure 2 In the process shown, obtaining the required electricity consumption of each building in a unit time period includes:

[0075] S201. Continuously or periodically detect the power consumption of each user within a unit time period of each building.

[0076] Specifically, a power meter can be set in each household of each building, which can continuously or periodically detect the electricity consumption of each user in the building in a unit time period.

[0077] S202. Calculate the average value of power consumption of each user in the building within a unit time period obtained through multiple detections.

[0078] In the actual detection process, there will be detection errors, or the power consumption of users may fluctuate slightly in different unit time periods. In ord...

Embodiment 3

[0085] Please refer to the attached image 3 , which shows the flow of the photoelectric usage control method for multiple buildings provided by Embodiment 3 of the present invention.

[0086] image 3 In the process shown, the excess electric energy of the solar power generation system corresponding to the positive difference is supplemented to the solar power generation system corresponding to the negative difference, including:

[0087] S304. According to the absolute value of the difference, classify the solar power generation systems corresponding to the negative difference from high to low.

[0088] In this step, in order to achieve a better power supplement for the solar power generation system corresponding to the negative difference, it is best to first understand the power shortage situation of the above solar power generation system, and then make different ways to supplement the solar power generation system with different power shortage degrees. Electricity. In...

Abstract

The invention provides a method for controlling photoelectricity usage in multiple buildings, each of the buildings is provided with a solar power generating system that provides electrical energy for the users of the building. The method comprises the following steps: obtaining the electricity consumption required by each building per unit time period, and the electricity generated by the solar power generating system that provides the electrical energy for the building; calculating the difference between the electricity generated by the solar power generating system for each building and the electricity consumption required by the building; and providing the excess electrical energy of the solar power generating system corresponding to the positive difference for the solar power generating system corresponding to the negative difference as a supplement. As compared with the background technologies, the method provided in the invention for controlling photoelectricity usage in multiple buildings enables the buildings to photoelectrically complement each other, in such a way that the reasonable distribution of the photoelectricity usage is realized as required by the users. The invention also provides a system for controlling the photoelectricity usage in multiple buildings.

Description

technical field [0001] The invention relates to the technical field of solar power generation, in particular to a photoelectric usage control method and system for multiple buildings. Background technique [0002] Solar energy is an inexhaustible clean energy. Solar energy is more and more favored by people because of its clean, renewable, and abundant resources. Among many fields of solar energy utilization, the field of solar power generation develops most rapidly, and the technology of solar power generation is most widely used. [0003] Although the solar power generation technology develops most rapidly, the solar power generation system still exists as an auxiliary power supply system of the thermal power generation system due to its small power generation scale. In order to build a low-carbon, environmentally friendly, and energy-saving community, it is essential to use solar power to generate electricity. [0004] The existing community solar power generation syst...
