Qinghai large-scale photovoltaic power generation strategy optimization technology further enhances new energy delivery capabilities

On the 16th, the reporter learned from the headquarters of the State Grid Co., Ltd., I learned that the control strategy optimization technology project of the large-scale photovoltaic power generation led by the National Net Qinghai Province Power Company is successfully passed the project review, innovation The results are highlighted, and the overall international advanced level is met. The project research results will continue to be applied to the temporary performance optimization of the Qinghai DC to send, Shaanxi DC, Xinjiang, etc., etc. DC transmission capacity, further serving the western province clean energy electricity delivery.

Since the 2019 project, the National Network Qinghai Province, the power company, give full play to the new energy in Qinghai and its own technical advantages. After the high-proportion of photovoltaic access DC near-area power grid, the power grid lacks transient effective active support for system stability and decline. Analyze the transient feature control mode and control parameters affecting the photovoltaic power plant, and proposes the photovoltaic power failover critical parameters extraction, control, and parameter optimization methods, and solves the adaptability of the photovoltaic power control parameters on the power grid under the multi-target stabilization constraint. Puzzle, constructing grid demand – parameter optimization – parameter test – new energy power generation transient performance optimization technology system for simulation checks, completing new energy power generation transient performance optimization practices, after 2 years of technology The research, a number of scientific and technological innovation results, the project published 7 core papers, and applied for 3 invention patents. Combined with project research conclusions, National Network Qinghai Electric Power has been completed by 500,000 kilowatt-wave parameters optimization pilot in Qinghai Haixi, and enhances 200,000 kilowatts of new energy delivery capacity in Haixi.

In accordance with the 2020 wind and photovoltaic utilization hours, the number of new energy generated billions of kilowatts is added, and the isometric replacement coal is equivalent to saving electric coal million tons.
