Abstract

The invention discloses a power system DC link optimized operation curve generation method and system. The method includes: generating a DC link typical operation curve according to static data and dynamic data of a power system and performing correction; the method comprises the following steps of: establishing an electric power system security constraint unit combination model with hour as granularity based on a typical operation curve of a DC link, constructing constraint conditions of the electric power system security constraint unit combination model, allowing the DC link to perform power and adjust the cost on the basis of the typical operation curve, and generating a DC link optimized line curve to serve as a reference when planning boundary conditions are formulated in actual power system planning. According to the method, the optimized operation curve used for replacing the typical operation curve of the traditional two-section DC link can be provided, and reference is provided for power system planners when planning boundaries are formulated.

Description

technical field [0001] The invention belongs to the technical field of electric power system planning, and in particular relates to a method and a system for generating an optimal operation curve of a direct current tie line of an electric power system. Background technique [0002] The DC transmission system has the characteristics of strong line transmission capacity, low loss, and asynchronous operation. It has obvious advantages in long-distance transmission, and is especially suitable for long-distance transmission of large-scale clean energy across provinces. Areas rich in wind power and photovoltaic resources are suitable for the development of various types of clean energy power generation, but at the same time, the problem of consumption is introduced. Vigorously developing DC transmission technology and building large-capacity DC transmission channels in new energy-prone areas and load centers is a feasible solution to the above problems, and has been applied in my...
