Peak shaving auxiliary service market transaction subject-oriented allocation upper limit dynamic adjustment strategy

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...

Problems solved by technology

[0003] Under the current operating rules of the peak shaving auxiliary service market, the actual deep peak shaving income of thermal power companies is lower than expected, and the income is damaged, resulting in stagnation in their enthusiasm for participating in peak shaving, and even a rebound trend

The reason for this problem is, on the one hand, the mismatch between the growth rate of new energy installed capacity in Northeast China and the deep peak-shaving capacity of thermal power enterprises; The failure of the method to reasonably divide and apportion responsibilities is the main reason for the shortfall of peak shaving fees
