Two-part Tariff Of Natural Gas Power Generator

China is facing a severe environmental situation,the need to vigorously develop clean energy.The proportion of renewable energy in power system is increasing day by day.However,renewable energy power generation has intermittent,random and anti-regulation characteristics,which increases the instability of system operation and requires more flexibility in the system.power supply.The gas unit has the characteristics of quick start and stop,flexible operation,and its environmental advantages compared with coal-fired units with less pollutant emissions,making the gas unit to become the ideal power system flexible power supply.At present,the cost of power generation in China is still relatively high,and the existing electricity price mechanism can not guarantee the gas unit recovery costs and obtain a reasonable profit,in addition to the current electricity market mechanism is not conducive to the gas unit in the existing electricity market Income,which have greatly affected the gas generating units of the enthusiasm.Therefore,China urgently needs to establish a scientific gas unit electricity price mechanism,in order to encourage gas units to provide quality services for the grid,the grid to accept more proportion of renewable energy to provide favorable conditions.In order to ensure the fair and reasonable income of the gas unit,this paper proposes a two-part price mechanism for the gas unit which can adapt to the present situation of power system and the level of power market.The paper first analyzes the technical advantages and economic characteristics of the gas unit and compares it with the economy and environmental protection of the coal-fired units.Secondly,based on the analysis of the fluctuation and fixed cost of the gas unit,the design of the gas-Two-part tariff and capacity-price are based on fuzzy cluster classification pricing,electricity price through the electricity market to participate in the auction.Based on the theory of operating period electricity price,the capacity price model of gas generating unit is established.Based on the model,the fuzzy cluster theory is used to build the model of gas price based on fuzzy clustering,which makes unit pricing get rid of " The pricing model and strategy of the unit participating in the electric energy market and the auxiliary service market are given in the paper,respectively.Firstly,the paper analyzes the relationship between the electricity price and the electricity price.In the end,this paper analyzes the calculation of capacity price based on fuzzy clustering and the example of electricity price participating in market competition,and validates the validity of the proposed model and method.
