Improving the Utilization Rate of Wind Power Based on the Thermal-Electricity Combined Operation Technology

Abstract:

As large scale integration of wind power generation into grid, the fluctuation of wind power must be stabilized with fast response complementary power source such as gas and oil power generation. However entire power system is dominated by thermal power plant in China, moreover the proportion of heating units is more and more high. Therefore, expanding the peak regulating capacity of heating units to take in wind power on a large-scale is an inevitable choice. This research proposed the heat load and wind power forecast approach, meanwhile, the analysis strategy of forecasting uncertainty is also be put forward. Then, a thermal electricity combined (TEC) operation technology, which based on making the best use of the heat transfer and thermal storage characteristics of heating network and electric heating, is proposed in this paper to enhance the utilization of wind power. Final, a practical system block diagram is proposed for practical application.
