Analyzing Information Disclosure in the Chinese Electricity Market

Abstract

Electricity generation relies heavily on fossil fuels in China, and this has posed great challenges for sustainable development. In 2015, China launched a new series of power reforms, aimed primarily at sustainable development and building a competitive power market system, where an information disclosure system plays an important role. This paper analyzes the effects of sensitive information disclosure, constructs different information disclosure scenarios, and compares the market clearing results under different scenarios. The results show that information transparency is conducive to the promotion of market efficiency. However, some problems, especially collusion, arise and inevitably bring negative impacts to the power market. Therefore, more attention should be paid to the content and quality of data transparency to avoid manipulations in the market. The data of power systems are complex and various, and thus big data applications may be conducive to effective information disclosure and better market regulation. Moreover, disclosure delay will help the electricity market become more transparent by reducing the risk of collusion. Besides, the information’s scope and contents, timing should also be taken into consideration. These findings may provide some references for the sustainable development of the electricity industry and have certain policy implications for policymakers.

Implementation of Efficiency Tracking and Evaluation Algorithm for Agricultural Product Circulation Based on Radio Frequency Data Tags and Android Platform

“…1 clearly stated that "strengthen the system construction to promote the fair trade of agricultural products and improve the circulation efficiency" [13]. The circulation of agricultural products is a complex system in terms of system, which includes not only the circulation problems of micro-enterprises, but also the sum of the relationship [14] between the production and sales of agricultural products, such as the main body of circulation, the circulation carrier [15], the circulation intermediary, the circulation market, and the supporting system. In 2017, the output of vegetables and fruits in my country was about 817 million tons and 250 million tons respectively [16], and the output of aquatic products and meat reached 64.453 million tons and 86.544 million tons respectively, ranking first in the world for many consecutive years [17].…”

Regional electricity market price forecasting based on an adaptive spatial–temporal convolutional network

“…From the existing electricity market's perspective, the spot market's electricity price fluctuates widely and is easily affected by the relationship between supply and demand, emergencies, environmental changes, bidding strategies, and renewables (Yang et al, 2021). Therefore, the accurate prediction of electricity prices has received significant attention from researchers (Jin et al, 2021).…”

Research on the Trading Arrangement and Clearing Model of Medium- and Long-Term Inter-Provincial Markets Considering Security Constraints

“…The open-access same-time information system is a necessary condition for the process of establishing a competitive power market. Jin et al adopted a game model to analyze the behavior of market participants and calculated different market-clearing prices (MCPs) under different information disclosure scenarios (Jin et al, 2021). The security region method is popular in power system security analysis (Xiao et al, 2019).…”

“…The security region method was adequately studied in (Yu et al, 2020). The shortcomings of existing works are as follows: 1) The existing works in Li et al (2019), , Jin et al (2021) focus on the billing and clearing models of inter-provincial trade in China, but the security region has not been given enough credit by the market operator. 2) The current market mechanism considers no security constraint in the early stage of market clearing, and many trading schedules are unreached due to grid security issues.…”
