英文摘要：

In order to cope with the great challenge of large-scale new energy access power grid, the conventional unit model including output and peak regulation characteristics are set up through further research of conventional units and new energy stations for Ningxia area. New energy production simulation system is developed considering the grid constraint which can be used for quantitative evaluation of adaptability for new energy power genetration and economy of new energy planning. The simulation result shows that validity and advancement of the system can provide technical support for the planning and operation departments of new energy.
