Qinghai large-scale photovoltaic power generation and network issues to be addressed

March 9, Qinghai Power Grid large-scale photovoltaic power generation and network planning and operation control key technology and application of scientific and technological achievements, and passed the results of identification of the Qinghai Provincial Science and Technology Department. The Committee of Experts believe that the results of the project as a whole reached the international advanced level.

Qinghai Electric Power Company from the start of 2009, with the government planning, the timely establishment of photovoltaic grid-related research projects, together with China Electric Power Research Institute to conduct a joint study. The project is to solve the solar cell photovoltaic power generation and the coordinated development of power planning on the one hand, to create the conditions for the photovoltaic dissolve; predict the other hand, security and stability control, photovoltaic power from photovoltaic, scheduling and control key aspects to solve the problems faced by the Qinghai photovoltaic power generation.

Qinghai large-scale photovoltaic grid to solve the main problem: light resources are concentrated in the Hercynian and Hainan, away from the load center of Qinghai, and weak regional power grid; photovoltaic short construction period, power networks sent a long cycle of construction projects PV development planning and network development plan, the need to coordinate and advance the construction of the supporting grid facilities; volatility of photovoltaic power generation, it is difficult to accurately grasp its power generation output to bring some pressure on the grid of peaking, FM, regulator, coupled with the Shanghai West regional power grid affected by the Qinghai-Tibet Interconnection Project, Seager electric iron, small hydro, and other factors.

The project's research guide scientific and reasonable to carry photovoltaic power generation and network planning, the Qinghai wind turbine inverter photovoltaic power generation capability to accommodate increased dramatically million-kilowatt photovoltaic power generation in the Qinghai power grid safety and stable operation and maximum consumer satisfaction photovoltaic power generation has important. More important this project is to promote the development of China's photovoltaic power generation demonstration role, the research results can be applied to government agencies, photovoltaic power plants and power grid enterprises laid the technical foundation for China's large-scale photovoltaic grid security consumptive .

In the process of research and development projects, the organization and management of the company is mainly responsible for the project in Qinghai, the coordination of work, the results of the project. Through the Qinghai Power Grid PV grid planning studies, the safe and stable operation analysis and grid photovoltaic accepted capacity analysis, a series of innovative achievements with independent intellectual property rights came into being, such as the protection of the power system to the large-scale photovoltaic access safe and stable photovoltaic Transient and steady-state simulation model.

These outcomes can be comprehensive, effective, and strongly support the the Qinghai grid photovoltaic power generation and network planning and scheduling run control, to improve the overall security and stability of power system operation and utilization of renewable energy. Compared to the main technical content of the research projects at home and abroad of similar technology has advanced and originality. At present, the research results have been used in Qinghai photovoltaic development planning, power station construction and network operation.

For the larger challenge, improve grid photovoltaic power generation and network planning and scheduling operation level, the next step, Qinghai will further improve the existing functionality, the development of new sub-functions to adapt the Qinghai grid photovoltaic power generation dispatching operation of changing control of the actual demand , and based on the Qinghai Power Grid to its own characteristics, to carry out the scenery water fiery energy storage power joint optimization of the scheduler is running system research and development of technologies and applications, and further reduce system peaking pressure, promote renewable energy consumptive.
