Description

technical field [0001] The invention relates to the field of optimization of offshore wind power energy storage capacity allocation, and relates to an optimization method and device for offshore wind power energy storage capacity allocation. Background technique [0002] With the continuous deepening of the national energy supply revolution and energy structure transformation, non-aqueous renewable energy represented by offshore wind power has made great progress, and has played a positive role in promoting the realization of the carbon peak and carbon neutral vision on schedule. effect. However, the continuous development of offshore wind power in Guangdong and Jiangsu will bring greater pressure to the safe and stable operation of the power system: on the one hand, wind power has typical anti-peak characteristics, and the matching degree between output characteristics and load characteristics is generally low. It is difficult to realize full consumption; on the other hand...

Problems solved by technology

[0004] However, the existing technology still has the following defects: the microgrid energy storage layout method is mainly suitable for off-grid systems, the energy storage location and operation mode are simple, and it is difficult to consider many alternative hidden benefits of energy storage in the main large-scale power grid; The renewable energy storage configuration method is more suitable for new energy categories with strong predictability such as photovoltaics, and has great limitations for new energy sources with more random output such as offshore wind power, and does not consider the development of offshore wind power clusters. Under the constraints of power grid transmission conditions; based on the energy storage configuration method with the smallest wind power output fluctuation, the optimization dimension considered is relatively single, and the energy storage operation under various operating modes such as positive peak regulation, reverse peak regulation, and flat peak regulation of wind power cannot be analyzed in depth way difference
