In the environment of energy structures adjustment, the reasons for wind and photovoltaic curtailment phe- nomenon are discussed according to the current situation of wind power and photovoltaic development and the current process of the ultra high voltage main grid construction. Combined with the actual test data of a power plant, the regula- tion characteristics and quantitative data of multiple power supply are summarized. Feasibility and reliability of the multi sources coordinated real-time control technology are analyzed based on the measured data. And then several real- time control technologies arc elaborated, which include the optimization and control technology of wind and thermal power, joint optimization scheduling strategy of wind, thermal and hydropower, complementary control strategy of wind, thermal and storage, and the real-time control methods considering network constraint and power transaction scheme. The results show the advantages of multi-source coordinated control which provides technical support for the planning, design and operation of large-scale wind power, photovoltaic, hydropower and thermal power coordination system. The research in this paper has a reference value for the construction of China＇s new energy power station and real-time control of new energy transmission.
