The invention discloses a dynamic compression method and system for power grid operation state data. The method comprises the following steps: acquiring power grid real-time data and power grid state topology; constructing a sparse matrix according to the obtained real-time data of the power grid in combination with the state topology of the power grid; calculating a compression index of the sparse matrix; and selecting an optimal compression method from a plurality of compression methods according to the compression index to perform compression processing on the sparse matrix to obtain compressed data. A compression strategy is dynamically adjusted in different power grid operation situations by adopting a dynamic sparse matrix compression method, and an optimal compression algorithm is dynamically selected according to actual conditions, so that the compression efficiency is improved, and efficient data processing and storage are realized. 本发明公开了一种电网运行状态数据的动态压缩方法及系统，通过获取电网实时数据以及电网状态拓扑；根据获取的电网实时数据，及结合电网状态拓扑构
