[0002] With the gradual opening of the power market and the advancement of market-oriented reforms, power trading models have become increasingly diversified, covering multiple forms such as day-ahead markets, real-time markets, and medium- and long-term contract transactions. This change has led to a surge in the amount of power trading data and a more complex structure. Traditional manual processing and single-dimensional analysis can no longer meet the needs of efficient and accurate settlement. At the same time, green power trading has become an important trend with the advancement of global climate change and sustainable development goals. Especially in China, the volume of green power trading has increased significantly, emphasizing the need for accurate measurement of renewable energy generation and green power value assessment. Against this background, the intelligent transformation of the power system, especially the construction of smart grids, requires power trading and metering systems to be more intelligent and automated.

[0003] Therefore, it is necessary to design a practical power trading settlement system for the provincial power trading center to provide more sophisticated business support for power trading settlement, connect resource allocation, metering accuracy and settlement efficiency, avoid the impact of the limitations of traditional manual sampling and single-dimensional analysis and settlement on power trading activities, identify potential trading risks, ensure the compliance of power trading activities, and adapt to changing policies and regulatory requirements.

[0083] The following takes the operation of the practical system for power trading and settlement of the Hubei Power Exchange Center in a certain month in the second half of 2024 as an example to illustrate the relevant achievements of the present invention. The actual transaction volume in the province reached 8.625 billion kWh that month, of which the proportion of coal-fired power generation units on the grid reached 65.2%, and the proportion of new energy power generation on the grid was 34.8%. The system automatically verifies and compares, and the cumulative settlement volume is 1.542 billion kWh.

On the power generation side, after the RPA robot automatically logs into the platform to extract time-sharing on-grid power data and daily clearing real-time settlement data, the proofreading unit on the power generation side successfully identified that the deviation volume reached 134,700 kWh. Through automatic comparison and anomaly detection, the abnormality rate in the deviation volume is 2.8%, which is 20% less than before. In the daily clearing bills on the electricity consumption side, the system extracted the electricity consumption data of power sales companies and wholesale users and verified a total of 287,000 daily clearing bills on the electricity consumption side. The system automatically identified 56,000 abnormal records, of which the deviation electricity exceeded the preset range by 24,000 kWh. By timely adjusting the verification template, the verification accuracy rate was increased to 98.7%, an increase of 4.2%.
