关于电力市场竞价行为的研究中，最重要的一个因素是发电成本。由于发电商的

One of the most important factors in the study of bidding behavior in the electricity market is the cost of electricity generation. Since the bidding purpose of the power generator is to maximize profits, the bidding cost of the power generator greatly affects its bidding strategy. Therefore, in order to effectively calculate the cost of power generators and describe it as a cost function of power generators, we will better study and analyze the bidding behavior of the power market. According to the costing characteristics, it is divided into two types: internal cost and external cost. The former's main cost items are the same as traditional accounting, including fuel costs, electricity purchase costs, water costs, material costs, wages, benefits, depreciation costs, repair costs, and other costs. The latter refers to the costs caused by negative externalities in production and consumption. The most obvious example is environmental damage. The internal cost is the main object in the generation cost accounting of power generators. In addition, according to the criterion that the cost changes with the amount of power generation, it is divided into fixed costs and variable costs. Fixed cost, as the name implies, is that the total cost can remain the same, regardless of the increase or decrease in the output of the product, it will not change, or the change is very small. Variable cost refers to the cost changed by the change of the output of goods

One of the most important factors in the study of the bidding behavior of the electricity market is the cost of power generation. Since the power producer's bidding purpose is to maximize profit, the generator's bid cost greatly affects its quotation strategy. Therefore, in order to calculate the cost of power generation, it is described as the cost function of power producers, it is better to study and analyze the bidding behavior of the power market. It is divided into internal and external costs according to cost accounting characteristics. The main cost items of the former are the same as traditional accounting, including fuel costs, purchase costs, water costs, materials, wages, benefits, depreciation costs, repair costs and other costs. The latter refers to the cost caused by negative externalities in production and consumption. The most notable example is environmental damage. Internal cost is the main object in the cost accounting of power generation. In addition, according to the cost with the power generation of the standard, it is divided into fixed costs and variable costs. Fixed costs, as the name implies, is that the total cost can remain the same, let the product output increase or decrease changes, will not change, or change very little. Variable costs are costs that vary as a result of changes in commodity production

The most important factor in the study of bidding behavior in electricity market is generation cost. Because the purpose of bidding is to maximize the profit, the bidding cost of power generation companies greatly affects their bidding strategy. Therefore, in order to effectively calculate the cost of power generation companies and describe it as the cost function of power generation companies, we can better study and analyze the bidding behavior of power market. According to the characteristics of cost accounting, it can be divided into internal cost and external cost. The main cost items of the former are the same as those of the traditional accounting, including fuel cost, power purchase cost, water cost, material cost, salary, welfare, depreciation cost, repair cost and other costs. The latter refers to the cost caused by negative external effects in production and consumption. For example, the most obvious example is environmental damage. Internal cost is the main object of power generation cost accounting. In addition, according to the standard that cost changes with power generation, it is divided into fixed cost and variable cost. Fixed cost, as the name implies, means that the total cost can remain unchanged, and the increase or decrease of product output will not change, or the change is very small. Variable cost refers to the cost changed by the change of commodity output<br>
