Abstract

The invention discloses a peak shaving auxiliary service market transaction subject-oriented allocation upper limit dynamic adjustment strategy. The strategy specifically comprises the following steps of: predicting new energy power generation power and a load curve of the next day in a power system; establishing a target function by taking the maximum comprehensive benefit of each transaction subject in the market as a target, and setting constraint conditions; and solving the target function through simulation software, and obtaining dynamic allocation upper limit adjustment parameters of all transaction subjects of the market; According to the method, the allocation upper limit is dynamically adjusted according to the Pareto optimal principle, benefit allocation of market participants is more reasonable, and the adjustment strategy is used for motivating decentralized decisions made by the market participants to be consistent with expectations of market designers; the adjustment strategy guarantees the reasonable income of thermal power enterprises, guides the thermal power enterprises to actively excavate peak regulation potential, saves power generation space for new energy, and relieves peak regulation trapping of a power grid; and the strategy better adapts to the change of future scenes, and guides the market to develop towards a healthy and reasonable direction all the time.

Description

technical field

[0001] The invention belongs to the technical field of improving the apportionment method of the peak-shaving auxiliary service market, and in particular relates to a dynamic adjustment strategy of the upper limit of the apportionment for transaction subjects in the peak-shaving auxiliary service market. Background technique

[0002] In recent years, the installed capacity and power generation of new energy have grown rapidly. The latest data from the National Energy Administration shows that by the end of 2020, the installed capacity of wind power in Northeast China was 34.3147 million kilowatts, and the power generation was 72.776 billion kwh, accounting for 13.41% of the power generation; the installed capacity of photovoltaic power generation was 1381.88 10,000 kilowatts, generating 18.767 billion kwh, accounting for 3.46% of the total. The Northeast Energy Bureau actively responded to the national call, constantly adapted to the new situation of Northeas...

Embodiment

[0179] Taking the actual load curves, new energy forecast curves and new energy actual output curves of four typical days in a certain place as figure 2 , image 3 , Figure 4 , Figure 5 shown, according to figure 2 , image 3 , Figure 4 , Figure 5 It can be seen that the maximum loads are 23273MW, 24230MW, 26720MW, 27295MW, the minimum loads are 19308MW, 19223MW, 23096MW, 22643MW, and the maximum new energy output is 3676.6MW, 3557.9MW, 4749.7MW, 5431.4MW. The minimum values ​​are 1513.6MW, 1703.1MW, 1142.5MW and 511.1MW respectively. A total of 72 start-up thermal power units were selected on a typical day, and their specific parameters are shown in Table 1.
