Capacity Compensation Price Accounting of Coal-Fired Units Under the Background of New Power System
China is in the early stages of power market reform. With the gradual decline in the utilization hours of coal-fired power generation， it is difficult for coal-fired power units to recover all fixed costs by electricity price alone. This can trigger sharp fluctuations in electricity prices， which in...

| description | China is in the early stages of power market reform. With the gradual decline in the utilization hours of coal-fired power generation， it is difficult for coal-fired power units to recover all fixed costs by electricity price alone. This can trigger sharp fluctuations in electricity prices， which in turn has socio-economic impacts. To compensate for the loss of coal power in power generation， this study considers utilization hours and operation status. Combined with the capacity price policy issued by the state， based on the unit compensation capacity accounting model， this study developed a capacity compensation price model for coal-fired power units and proposed a capacity compensation cost allocation method for industrial and commercial users. First， a compensation capacity accounting model was constructed based on the available capacity， power consumption， and maintenance of coal-fired power plants. Second， the K-means clustering algorithm was used to determine the probability of power generation of coal-fired units， and a capacity compensation electricity price model considering the fixed cost， capacity subsidy factor， and profit and loss balance point utilization hours was constructed. A capacity cost allocation method for industrial and commercial users was established based on this. Through the above analysis， the capacity price and other factors of power plants A， B， and C in G province are evaluated by simulations. The simulations verify the calculation of the coal power capacity compensation price， which has a far-reaching impact on coal power units and users. Therefore， traditional coal-fired units should seize policy opportunities to promote their transformation into system regulations and basic security power units to help build a new type of power system. |
