Abstract

The trans-provincial and trans-regional power transmission of the southwest giant hydropower station involves complex multi-dimensional hourly generation curve decomposition with monthly energy demands. This needs to consider complex power grid peak shaving and other needs, which is an important problem to be solved urgently for the monthly power generation and operation of the hydropower station. This study constructs a monthly contracted electricity curve decomposition model suitable for trans-provincial and trans-regional power transmission giant hydropower stations. Considering the differences in electricity prices of three types, i.e. guaranteed quantity and guaranteed price, guaranteed quantity bidding and marketization, as well as the complex constraints of power grid peak shaving, market and power station operation, this paper puts forward the secondary planning goal of maximizing the total revenue of multi provincial and multi variety power generation, The mixed integer linear programming method is used to solve the model efficiently. The model is verified through two different application scenarios of a real hydropower station in dry season and flood season. The results show that under the boundary conditions of peak load regulation that meet the requirements of the power grid, the power generation income of the power station can be effectively improved by optimizing the multi-scale and multi variety power and output distribution of the two provinces and giving priority to the distribution of market-oriented power to the peak load and flat section.
