Research On Evaluation Indices And Evaluation Method Of Electricity Market Operation Under The New Round Of Electricity Reform

The announcement and implementation of the "Document 9" issued in 2015 and the corresponding supporting documents marked the beginning of the new power reform.The pilot provinces have taken the reform of the electricity sales side and the reform of the spot market as an important part of this round of power reform.With the continuous deepening of the reform,the market environment has become increasingly active and the market development has gradually improved.The rapid growth of the market size and the continuous enrichment of market transaction models have put forward higher requirements for market operations and supervision.The original power market evaluation system based on long-term transactions is increasingly unable to adapt to the current pace of development of China’s power market.To this end,this article introduces the theory of industrial organization to optimize the evaluation indicators.Focusing on the rapidly developing energy market,capacity market,and ancillary service market under the new power reform,the following studies are conducted:In order to measure the price level of the electricity spot market,a spot price index based on the Marshall-Edgeworth index system is proposed,and examples are used to verify that the index has statistical characteristics of high kurtosis and low variance compared to traditional weighted indexes.This index can be used for Measure the price levels of various markets such as energy,capacity,ancillary services,and demand response in this indicator system.Then,in response to the abnormal fluctuation of the spot market price,a spot market price monitoring model based on Bollinger’s principle was proposed,and a parameter sensitivity analysis was performed in combination with actual examples.The consistency parameter was used to obtain the optimal parameter value,and the model was analyzed.Characteristics and scope of application.By introducing the SCP(structure-behavior-performance)paradigm in the theory of industrial organization as the theoretical basis,the synchronization of power transmission and distribution in the power industry and the generality of market transactions are comprehensively considered.feasibility.Considering the important position of the spot market in the new power reform,the spot price index and abnormal volatility of the spot price were introduced to establish a market structure,market operation,and market performance index system based on SCP theory,which was used to evaluate the operation of the power market under the new power reform.According to the statistical characteristics of each evaluation index,the corresponding utility function is selected for dimensionless processing,and then the maximum membership degree method and the weighted average evaluation method are combined for weighting.Based on the multi-level fuzzy comprehensive evaluation method,the power market operation synthesis is established.The evaluation model,and using the 2017-2019 market operation data of the Guangdong power market as an example,explored the reform and development results of the Guangdong power market in three years and the deficiencies in market construction,indicating the future spot market reform and construction.direction.The power market operation evaluation indicators and evaluation methods proposed in this paper not only provide market monitors with new tools for market monitoring,but also provide a new perspective for market mechanism improvement for power market reform.
