Constraints and Sensitivity Factors of Large-scale New Energy Grid-connected Grids to New Energy Utilization Impact Study

In this paper, time series production simulation method is used to study the utilization rate of large-scale new energy grid with and without grid constraints. Based on the grid free constraint model, the influences of new energy installation, total social electricity consumption, inter-provincial electricity transmission, flexible transformation scale of coal power and energy storage development scale on the utilization rate of new energy are analyzed. Finally, some suggestions and measures to improve the utilization rate of new energy in S power grid are put forward.
