Research On Monthly Concentrated Bidding Transaction Model Of Yunnan Power Market

In March 2015 China launched a new round of reformation in electric power system.The general idea is "Control the middle,release both ends".The government will tighten the supervision on grid enterprises,check and ratify transmission-distribution price.Meanwhile release the price regulation in generation and consumption links.After the reform,the price of electricity consumption is composed of three parts:market price,transmission and distribution price and government fund.Among them,the market price refers to on-grid price which is negotiated by customer and power generation enterprises or generated by pricing mechanism of centralized competitive trading markets.The centralized bidding in the electricity market is divided into the concentrated bidding(matching transaction)and the unilateral listing transaction.This master thesis is aimed at the modeling study of the monthly concentration competition market in Yunnan Province in 2017.This thesis focuses on three questions:First,whether the price formation mechanism of monthly centralized bidding transaction in Yunnan electricity market is reasonable?Second,can participants develop a centralized bid(match)transaction model?Third,how to use the model to provide decision support for the participants?Five major studies have been carried out in this paper:1.Research on the economic principle and price formation mechanism of the centralized bidding(matching)trading mechanism in the electricity market;2.Study the formation mechanism of the Yunnan electric power market;3.Build a centralized bidding(match)transaction model;4.How to use the transaction model to fit the participants’ bidding distribution;5.How to use this transaction model to support participants make their decision in centralized bidding market.The author consulted a large number of historical documents,policy rules,professional books and advice form industry professionals.The author visit theNordic electricity trading center(http://www.nordpoolspot.com),PJM(http://www.pjm.com)and other foreign power market management or operation network station.In order to prove the price formation mechanism of Yunnan centralized bidding transaction is reasonable,this paper studies the premise which take the marginal price as the unified settlement price is this market should be a complete competitive market.But the analysis shows that Yunnan is not a completely competitive market.In order to build a successful transaction model,it takes 5 months to build the program,with a total of more than 30 versions.The transaction model is reliable and successful.Through the analysis,the paper draws the following conclusions:First,the provincial electricity trading mode need to combine with the characteristics of the market;Second,the mechanism of trading price formation of Yunnan centralized bidding market is designed to meet the characteristics of this market;Third,the development of electric power market centralized transaction model is feasible;Fourth,by using this transaction model,the distribution curve of the quoted price can be drawn out;Fifth,this transaction model can help the bidder to make a strategy reducing transaction risk and transaction cost.
