Cost Control Research Of QTH Electric Power Corporation Based On Price Competition

The current electric power reform, generation of electricity introduces competitive system, namely separation electricity generation from power net and first competitive price. Under the competition market environment, the power plant becomes operates independently, assumes responsibility for own profits and losses, the independent calculation, the tendering surfer competition entity. The most important question the power plant facing is how does control the cost and reduces the cost. The analysis on generating cost is the basis of price bidding and decision-making of competition strategy. It is also the foundation for power plants survive and development in power market.By the fact that analysis, this article discovered the QTH electricity generation company along with the load growth, the unit variable cost has the increase slightly, because the variable cost is the cubic of load, slope of the curve tends transient from drop to escalation consistently, namely surpasses the point of some load, the unit variable cost grows along with the load increase. But along with the load growth, the unit total cost and the electrovalence of no loss of capital assume the drop tendency, explained the economic efficiency of the enterprise is better along with the load, the unit cost is lower. It takes enterprise participate in the competition electrovalence positively, so long as the competition electrovalence is higher than the electrovalence of no loss of capital , the enterprise obtains the more profit.This article carried on cost analysis of energy-loss and analysis of profit and loss balance from the angle of profit maximization. According to the result of energy-loss firstly choose the factor of adjustment, it could control the cost effectively, and with the current transaction characteristic of electric power market to obtain under the different load no loss of capital electrovalence, is the foundation of competition electrovalence and realizes enterprise profit maximization.
