Abstract

The invention provides a coordinated source grid load control system for access of intermittent renewable energy to the power grid. The system comprises a layered and partitioned grid-connected key influential factor analysis module, a renewable energy set output characteristic representation module of multiple spatial and temporal distribution, a regional power production simulated calculation module based on multiple spatial and temporal scales and an intermittent renewable energy absorption capability measuring module. According to the invention, a renewable energy set output characteristicrepresentation equation of multiple spatial and temporal distribution is established, a power production simulated calculation module based on multiple spatial and temporal scales is established, renewable energy absorption measuring indexes are established, and the effect of a coordinated source grid load control strategy after that high-permeability intermittent renewable energy access the power grid is verified.

Description

technical field [0001] The invention belongs to the technical field of power grid regulation, and in particular relates to a source-grid-load coordination control system for intermittent renewable energy access to the power grid. Background technique [0002] At present, my country's existing power grid planning has not yet fully adapted to the impact of large-scale renewable energy access. When the project cannot be connected to the grid or does not meet the requirements of grid connection, the phenomenon of abandoning wind and light occurs from time to time. [0003] Hierarchical and partitioned operation is the inevitable result of the development of the power grid and the basis for the stable operation of the large power grid. The hierarchical zoning planning and operation of the power grid should be carried out in a reasonable hierarchical zoning according to the grid voltage level and power supply area. Reasonable stratification refers to connecting power plants and l...
