The invention discloses a provincial-level electric power spot market safety checking calculation method, device and equipment and a storage medium, and the method comprises the steps: regularly obtaining the real-time state result data of a regional power grid, carrying out the automatic checking of a stored state estimation result, deleting the result data which fails in checking, and carrying out the verification of the result data. Provincial electric power spot market calculation based on an abnormal regional power grid model is avoided; a province virtual control area part in regional state estimation is replaced by a province same-time state estimation result, equipment missing data of a state estimation result part is filled by an interpolation method, and the problem of state estimation result missing or large actual measurement deviation caused by network delay and instability is solved; based on a historically stored regional power grid state estimation result, a power generation ...

The invention discloses a provincial power grid day-ahead power generation plan compilation method, system and device and a medium. The method comprises the steps of obtaining a power grid physical model of a network dispatching area; respectively calculating sensitivity data of load nodes and in-province units to inter-province tie lines based on a power grid physical model; in-province unit operation parameters and system operation boundary data are obtained, and constraint conditions are constructed in combination with sensitivity data; constructing a target function by taking the minimum operation cost of the power grid as an optimization target; and solving the target function by considering the constraint condition to obtain an optimal day-ahead power generation plan. Based on the regional power grid model range, the method achieves the actual calculation of the inter-provincial tie line power flow, carries out the day-ahead plan adjustment according to the section constraint, avoids ...
