Operation Method of Source and Storage Collaborative Optimization for Improving Power Transmission Capacity in Hydropower Enrichment Areas
In view of the strong fluctuation and intermittency of renewable energy output,which leads to short-term heavy overload of power transmission section and the difficulty of clean energy transmission and accommodated,this pa-per proposes a source-storage collaborative optimization operation method to improve the power transmission capacity in hydropower rich areas.This method defines the quantitative index to measure the power transmission outside the section,and establishes a multi-objective optimization model with the goal of minimizing the power generation cost of the system,the largest output of the section and the minimum power consumption of energy storage.The best compromise solution is obtained by solving the Pareto frontier with combination of entropy weight double base point method.Finally,based on the provincial power grid example,the simulation results show that the method can effectively improve the power genera-tion of cross-sectional renewable energy through the collaborative optimization operation of hydropower,thermal power and energy storage,and promote the abandonment rate of renewable energy under the premise of ensuring the safe and stable operation of the system.
