Theory And Empirical Research On Regional Power Transmision Market Mode And Control Of Market Power

Under the deepening of the electricity market reform,China has basically formed a grid pattern of"national power grid as the core,regional power grid as a support,and the provincial power grid as the basis".On this basis,the regional electricity market is steadily carried out.Different regions of the grid structure are not the same.In addition,power grids between regions are different.These reasons will inevitably lead to transmission congestion, inter-regional price differences and price fluctuations.In order to achieve optimal distribution of power resources,inter-regional economic power,to alleviate transmission congestion and prevent sharp price fluctuations,solutions to these problems is to introduce transmission right mechanism.This paper took a comprehensive overview of transmission right and theories of control of market power,and studied theories of physical transmission rights and financial transmission right.On the basis of theories of transmission right,this paper designed a simplified mathematical model of transmission flow that can meet the requirements of accuracy and convergence in flow calculation and adapt the theory of transmission.This paper apply market equilibrium and price theory,production and demand function theory, optimization theory,game theory and other related power system analysis theory and method to study rational profit model,auction model,options pricing models,optional power flow and market equilibrium coordination model,economic dispatch model and of"point-to-to"financial transmission rights.As well as their solution method,constraints and feasibility of options-based model of financial transmission rights,optimization constraints determination, market equilibrium model and option hedging methods.And then,this paper studied the solution methods of auction model and reasonable profit model in option-based financial transmission right in detail and combined the Monte Carlo simulation algorithm to carry out a simulation of the utility of financial transmission right.And then,this paper made a preliminary design with the power option,forward contracts transactions and bilateral transactions(direct supply of large users) as the core of the pattern in regional transmission right market which based on analyzed the causes of market power in regional power market and its maintain mechanism and influence on the market of transmission right and established a market evaluation index system and designed measurement method of each indicator.Based on the studies of transmission right and market power,it used simulation data to verify the problems of avoiding transmission congestion by transmission right and got benefits through bidding strategy.Take an empirical research on the strategy of controlling the market power of generation under transmission right pattern with the actual operating data of a regional electricity market on the basis of empirical research put forward preventive strategies of regional market power.The results in the paper has great theoretical value and practical significance in the following research and implementation fields,such as"direct electricity purchase mode from large users and the relevant operation mechanism and rules","the model design of regional power transmission right market and the prevention measures of market power".
