With the increasing installed capacity of renewable energy,the problem of wind and solar power abandonment in systems with high proportion of renewable energy is serious. It is of great significance to carry out the research on the problem of renewable energy consumption and accurately position the resistance of renewable energy consumption to improve the formulation of renewable energy consumption measures. In this paper,a refined evaluation method of renewable energy consumption resistance for power system is proposed. Firstly,based on the power flow tracking algorithm,the power flow of network nodes is divided into three parts,namely conventional unit injection,renewable energy injection and load outflow. Secondly,from the point of view of network nodes,the mathematical relationship models of peak modulation,frequency modulation,node voltage deviation constraint and renewable energy consumption are established,and the coupling relationship among the three is considered to analyze the power abandonment of network nodes. Then,the evaluation model of renewable energy consumption resistance based on network nodes is constructed and solved,the key nodes of renewable energy consumption in the system are located. The restriction factors of renewable energy consumption of each node are defined and the renewable energy consumption resistance is quantified. Finally,an example is designed based on improved IEEE 39-bus system to verify the effectiveness of the evaluation method. The proposed evaluation method can provide a basis for the power sector to formulate measures to improve the consumption of renewable energy.
