The invention discloses a wind-solar storage primary frequency modulation coordination control system and method based on edge calculation, and the system comprises a main control station edge calculation intelligent terminal based on a new energy power station control room, and a sub-control station edge calculation intelligent terminal based on a photovoltaic power station, a wind power stationand an energy storage power station. The wind-solar storage primary frequency modulation coordination control system is characterized in that the structure of a new energy power station is changed, anenergy storage power station with a certain capacity is configured, and the energy storage power station participates in the primary frequency modulation coordination control system. The method comprises the steps of obtaining the grid-connected active and high-precision frequency data; judging whether the current frequency exceeds a limit value or not; performing primary frequency modulation byadjusting power; carrying out frequency modulation again by adjusting power; and judging whether the frequency returns to a normal range. According to the present invention, by utilizing an edge calculation container and a virtual technology, different frequency modulation algorithms are calculated at the same time and are weighted and averaged; and by utilizing the advantage of an edge computingterminal of rapid calculation of a lightweight algorithm, the system is close to an device terminal and is good in real-time performance.

Description

technical field [0001] The invention relates to the technical field of primary frequency regulation of new energy power stations, in particular to a coordinated control system for primary frequency regulation based on edge computing, wind and storage. Background technique [0002] Global climate change, the implementation of the Paris Agreement, especially my country's commitment to peak carbon emissions by 2030 and achieve carbon neutrality by 2060. The task of energy conservation and emission reduction is arduous. Adjusting the structure of energy supply and utilization is a major trend. Energy supply is mainly based on renewable energy, namely wind power and photovoltaic power generation, but wind power and photovoltaic power generation is random and closely related to climatic conditions. Therefore, when a high proportion of new energy power generation is integrated into the grid, it faces huge technical challenges in terms of grid dispatching and safe and stable operati...
