Simulation Research On The Impact Of Carbon Market On The Spot Electricity Market

In order to promote the adjustment of energy structure and give full play to the decisive role of the market in the allocation of power resources,China is accelerating the construction of the national carbon market and power market.The construction of the carbon market takes the power industry as a breakthrough and has taken the lead in conducting transactions;while the power spot market,as the core of the power market reform,is still in the trial operation stage.At present,the two market mechanisms operate relatively independently,and the power spot market construction plan has not fully considered the impact of carbon trading on market clearance.Based on this,this paper takes Jilin Province as an example to analyze the impact of the carbon market on the economic and environmental benefits of the power spot market.The heating season in Jilin is longer,and the power supply structure is dominated by combined heat and power units.Choosing Jilin Province for electricity spot market simulation has reference significance on how to effectively resolve the overcapacity of coal power and improve the construction of carbon market and electricity spot market under the condition of ensuring heating.This paper takes the operating cost as the evaluation index,comprehensively considers the constraints of power balance(including outgoing power output),load reserve,maximum and minimum output of the unit,and minimum output of heating must open,and establishes a unilateral trading power spot market based on dynamic queuing method.And on this basis,the unit’s carbon emission cost is calculated through the unit’s own carbon dioxide emission factor,free carbon quota allocation baseline value,carbon emission cost transmission rate,and the carbon price predicted by the hybrid panel regression model to consider the impact of the carbon market on the clearing results of the spot market and the utilization rate and carbon dioxide emissions of coal-fired generating units of different capacities.According to the market simulation,the following conclusions can be drawn:(1)Dealing with the relationship between the government and the market is the key to promoting the carbon market.The mandatory allocation and assessment of carbon emission rights led by the government is an important prerequisite for the formation of a carbon market;and the size of the trading rules of the electricity spot market and the market bidding space will affect the use and trading of carbon emission rights,and are an important foundation for the carbon market.(2)The carbon market occupies an important position in the low-carbon power transformation.The carbon market increases the cost advantage of large-capacity and low-energy units,while reducing the performance of low-efficiency units in the spot market,and can further tap the potential of coal-fired power generation and energy saving.(3)The carbon market also needs to support related auxiliary service market mechanisms.The implementation of the carbon market will cause some of the inefficient heating units to withdraw from the spot market transaction,which increases the difficulty of the company’s operation;and the increase in the proportion of clean energy generation such as wind power and photovoltaics will also place higher requirements on the safe dispatch of power grids.Therefore,in order to ensure the safe and stable operation of the power system,the carbon market also needs to provide related auxiliary service markets to encourage the coal-fired power generation units to undergo flexible transformation.
