Problems solved by technology

The characteristics of renewable energy will lead to a decrease in the proportion of moment of inertia of the power system connected to it, AGC (automatic generation control) control frequency adjustment capacity and mileage increase, power balance market peak-valley difference expansion, equipment failure rate increase and other series that lead to an increase in auxiliary services cost problem
With the large-scale development of renewable energy power generation, the system’s demand for conventional power auxiliary services will also increase. Whether conventional power sources can provide sufficient auxiliary services is crucial to the development of renewable energy power generation, although this role Not particularly easy to evaluate accurately and clearly, and will usually always be underestimated in practice

Embodiment 1

[0044] Such asfigure 1 As shown, the present invention provides a green certificate compensation method for auxiliary services in the electric power market, the steps are as follows:

[0045] Step 1: Obtain the officially submitted day-to-day forecast transaction power generation curve and the collected actual power generation curve of the day;

[0046] Step 2: Calculate the curve deviation according to the actual power generation curve of the day and the predicted transaction power generation curve data of the day;

[0047] Step 3: Calculate the corresponding number of green certificates according to the deviation of the curve, and compensate for the auxiliary services of the electricity market.

[0048] Step 1 includes:

[0049] First of all, it is necessary to obtain the forecast trading power generation curve of the day before the day officially submitted and the actual power generation curve of the day collected, and then perform subsequent calculations based on these tw...

Embodiment 2

[0059] Based on the same inventive concept, the present invention also provides a green certificate compensation system for power market auxiliary services, such as Figure 4 As shown, including: power generation data acquisition module, deviation calculation module and compensation module;

[0060] The power generation data acquisition module is used to obtain the officially submitted day-to-day predicted transaction power generation curve and the collected actual power generation curve of the day;

[0061] The deviation calculation module is used to calculate the curve deviation according to the actual power generation curve of the day and the predicted transaction power generation curve data of the day, and integrate the power at each moment to obtain the total integral deviation of the day;

[0062] The compensation module is used to calculate the corresponding number of green certificates according to the deviation amount, and compensate the auxiliary services of the elec...

Abstract

The invention provides a power market auxiliary service green certificate compensation method and system. The method comprises the following steps: acquiring the current-day actual generating capacity and the current-day predicted transaction generating capacity; calculating a deviation value according to the current-day actual generating capacity and the current-day predicted transaction generating capacity data; and compensating the power market auxiliary service according to the deviation value. While an auxiliary service provider is stimulated to provide high-quality auxiliary service, a renewable energy power generator is promoted to improve the prediction accuracy of self output; the auxiliary service cost caused by renewable energy power generation is shared by using the green certificate additional value, and the problem of unfair occupation of auxiliary service resources by renewable energy power generation is solved, so that the fair development of the auxiliary service market is promoted.

Description

technical field [0001] The invention relates to the field of electric power market, in particular to a compensation method and system for a green certificate of auxiliary service in the electric power market. Background technique [0002] The quota system combined with the green certificate transaction can play a role in discovering the real price of renewable energy, reflecting the currency value of the positive external characteristics of renewable energy, guiding renewable energy investment and grid optimization planning, and stimulating the production and consumption of renewable energy. Under the condition of large-scale renewable energy grid connection, the power system needs conventional energy to provide sufficient flexibility to cope with the uncertainty of renewable energy output. Therefore, it is necessary to establish a complete auxiliary service market to motivate market players to provide flexible auxiliary services. my country's current ancillary services are ...
