Abstract

An assessment method for online acceptance capacity of new energy power generation includes determining an objective function and various constraint functions, building an assessment model according to the objective function and the constraint functions, and through input of online data, calculating grid acceptance capacity of each new energy power generation station and the sum of capacities of accepting all the new energy power generation stations by a grid. According to the built assessment model, not only top and bottom bound restrictions of tie line power and unit output but also wire frame and peak regulation restrictions are considered, and the acceptance capacity, with the installed capacity as the highest limiting value, of each new energy power generation station is calculated, so that policy requirements on full acceptance of new energy power generation are met, safety factors of the grid is considered, and safe and stable operation of the grid is guaranteed.

Description

technical field

[0001] The invention belongs to the technical field of electric power system scheduling automation, and in particular relates to a new energy generation online acceptance capacity evaluation method. Background technique

[0002] With the rapid and large-scale development of new energy power generation, the impact and challenges it brings to the power grid are becoming more and more significant. In areas with large-scale development of new energy such as the Northeast and Northwest of my country, there have been occurrences of peak-shaving, voltage-regulating or transmission lines in the entire network. The limited output of new energy power generation caused by congestion is not conducive to the full consumption of new energy power generation, and it also affects the safe and stable operation of the power grid. Therefore, the power grid dispatching agency needs to incorporate new energy power generation into the unified and coordinated dispatch operation manag...
