Revenue Sharing Mechanism Of Hydropower And Thermal Power Co-ordination Based On Cost-Volume-Profit Analysis

The water supply situation of the hydropower station is very random.And the river runoff at each time period also randomly changes during different periods.Therefore,the amount of hydropower generation has great uncertainty.According to the National Renewable Energy Law,hydropower is a clean renewable energy source,hydropower and other renewable energy sources should be given priority and full consumption.In recent years,with the continuous expansion of hydropower installed capacity,hydropower generation has increased rapidly.At the same time,due to the impact of the current domestic macroeconomic downturn,the pace of electricity demand growth is significantly less than expected,and even negative growth has occurred.In some provinces,the proportion of hydropower is significant,and in the case of giving priority to the full consumption of hydropower,average available hour using for Thermal power generation is greatly reduced.The thermal power company suffered from operating difficulties and even serious losses.The amount of hydropower generation is uncertain,and thermal power is required to generate space for hydropower generation and to adjust peaks for hydropower.However,thermal power has not received due compensation and has not established a balance of interests mechanism in this area.In the current special power supply structure,thermal power companies lack a guarantee mechanism for their interests,and do not reflect fair and reasonable control principles.At the same time,the uncertainty of hydropower determines that thermal power needs to bear the main power generation responsibilities in the dry season,as well as tasks such as lumbar load,peak load,and peak load adjustment in other periods.Under the premise that thermal power companies must exist and there was a problem of hydropower consumption and thermal power co-ordination.Therefore,in hydropower consumptive at the same time,it is necessary to ensure the legitimate benefits of thermal power companies.It is necessary to seek a comprehensive and mutually acceptable balance of interests mechanism among the multiple systems of water and thermal power enterprises.The focus of this article is by using the basic principle of CVP analysis and economic control theory,the CVP model and a reasonable model of the thermal power company are constructed,compared analysis of the actual use of thermal power and the balance state of the use hours,established between Hydropower and Thermal power enterprise revenue sharing mechanism.Under the condition of the regulated economy,hydropower enterprises should get excess returns in high flow year under the condition of ensure the reasonable income compensation for thermal power enterprises did not achieve reasonable profits,because under the control system,as long as it's effective asset is in production,give play to the role of the corresponding assets must be and can only be reasonable or allowed to gain;On the contrary,in the dry year,the excess profits obtained by the thermal power enterprises should be compensated to the hydropower enterprises that have not reached the reasonable income in the case of reasonable income.The revenue coordination mechanism between Hydropower and thermal power enterprises is the intersection of government regulation and enterprise requirements,which guarantees the sustainable development of power enterprises.
