Problems solved by technology

3) In the case that renewable energy and traditional fossil energy power generation are all connected to the grid, for each individual power user, it is not possible to directly physically distinguish which are renewable energy and which are non-renewable energy used on the grid
However, the implementation of the current renewable energy consumption guarantee mechanism policy also requires accurate measurement of the user's renewable energy consumption, which the patent application cannot provide.
[0005]The paper "Discussion on Accounting of Renewable Energy Electricity Consumption Quota and Contract Performance Transaction Mode" ("China Electric Power Enterprise Management" Magazine No. 12, 2019) discusses the user-side The calculation of renewable energy consumption is actually mainly based on the results of relevant market transactions such as contract transactions to infer the renewable energy consumed by users. ; The statistical results will not be provided to users until the electricity bill is settled, and it will not be able to remind users in real time and track the consumption situation
3) Renewable energy is used to generate electricity for power users, but the power is insufficient, and the insufficient part is provided by the grid
In view of the above six situations, in the existing technology, real-time and accurate measurement of renewable energy power production, consumption, and on-grid power supply cannot be realized at the same time

Embodiment 1

[0071] figure 1 It is a flow chart of the measurement method of renewable energy electricity production and consumption. Such as figure 1 As shown, the present invention provides a method for measuring renewable energy power production and consumption, the method comprising the following steps:

[0072] S1: smart meter initialization;

[0073] In this step, the initialization of the smart meter includes:

[0074] Set the sleep cycle T and the measurement value update cycle T 0 , last updated battery value time T 1 The initial value of the initial value; set the initial value of the working mode M, set the local renewable energy power generation G, and the power supply to the grid G P and the locally consumed electricity G C The initial metering value: the default initial value is set to 0; set the total power supply D of the grid, the amount of renewable energy D C and fossil energy electricity D F Initial metering value of : the default initial value is set to 0; set ...

Embodiment 2

[0128] Such as Figure 4 As shown, the present invention also provides a renewable energy power production and consumption metering system, the system comprising:

[0129] The initialization module is used for smart meter initialization;

[0130] The judging module is used to read the current working mode of the smart meter, and judge whether the current working mode needs to be changed; if it does not need to be changed, judge whether the current measurement value update cycle has expired;

[0131] The update module is used to update the metering value according to the current working mode of the smart meter, and select And update the current working mode of the smart meter;

[0132] The sleep module is used for the smart meter to enter the sleep mode. If the sleep cycle expires or a wake-up event occurs during the sleep period, the judgment module will re-execute the judgment operation.

[0133] Preferably, the smart meter initialization includes:

[0134] Set the sleep ...

Embodiment 3

[0144] The present invention also provides a renewable energy power production and consumption metering system, the system includes: a processor and a memory coupled to the processor, the memory stores a computer program, and the computer program is controlled by the The method steps for realizing the method for measuring the production and consumption of renewable energy power in Embodiment 1 when the above-mentioned processor is executed.

[0145] In this embodiment, the method steps performed by the processor are the same as the method steps in Embodiment 1, and will not be repeated here.

[0146] Those skilled in the art should understand that the embodiments of the present application may be provided as methods, systems, or computer program products. Accordingly, the present application may take the form of an entirely hardware embodiment, an entirely software embodiment, or an embodiment combining software and hardware aspects. Furthermore, the present application may t...

Abstract

The invention relates to a renewable energy power generation and consumption metering method and system. The method comprises the following steps of: based on two metering modules, judging whether a current intelligent electric meter needs to change a current working mode according to current renewable energy power generation and load conditions; and metering the renewable energy power generationand consumption conditions in real time, and updating the current working mode of the intelligent electric meter as required. By adoption of the renewable energy power generation and consumption metering method and system provided by the invention, the real-time and accurate metering of the power supply quantity and the renewable energy consumption of a renewable energy power grid can be realizedin a complex power supply and consumption relationship among the power grid, the renewable energy power generation and a user load based on the intelligent electric meter.

Description

technical field [0001] The invention belongs to the field of electric power automation, and in particular relates to a method and system for measuring power production and consumption of renewable energy. Background technique [0002] The development of renewable energy is the development trend of the world's energy industry. In order to promote the production and consumption of renewable energy, foreign countries have generally implemented renewable energy power generation subsidies and renewable energy quota systems; domestically, on the basis of renewable energy power generation subsidies, renewable energy power consumption has also been implemented on the user side. For example, the "Notice on Establishing and Improving the Guarantee Mechanism for Renewable Energy Power Consumption" issued in 2019 (Fagai Energy [2019] No. 807), and the "2020 Renewable Energy Notice on the Weight of Power Consumption Responsibility (Fagai Energy [2020] No. 767), etc. The implementation ...
