Systems and methods for providing a memory sub-system controller that selectively performs extrinsic defect scan operations on certain word line groups of a memory sub-system are described. The controller performs an extrinsic defect scan operation on a set of predetermined portions of a set of memory components. The controller, in response to performing the extrinsic defect scan operation, stores a map that identifies a subset of the predetermined portions of the set of memory components having a reliability value that fails to satisfy a reliability criterion. The controller, in response to storing the map, performs one or more subsequent extrinsic defect scan operations on the identified subset of the predetermined portions of the set of memory components having the reliability value that fails to satisfy the reliability criterion.

Aspects of the present disclosure configure a system component, such as a memory sub-system controller, to modify pulses used to program memory components. The controller receives a request to program data in an individual memory component of a set of memory components. The controller computes a plurality of memory reliability criteria associated with the individual memory component and compares the plurality of memory reliability criteria to one or more threshold values. The controller selects a program pulse used to program the data to the individual memory component based on a result of comparing the plurality of memory reliability criteria to the one or more threshold values.

The present application belongs to the technical field of power system reliability evaluation and virtual power plant operation optimization, and provides a virtual power plant heterogeneous resource regulation capacity evaluation method and system. The technical scheme is that, for multiple source uncertainty variables, an empirical Copula function is obtained by fitting historical data, and a time series scenario set is generated based on the empirical Copula function and a trained stacked auto-encoder model. Based on the generated time series scenario set, the regulation capacity of all uncertainty scenarios is calculated, and a regulation capacity sample set is constructed based on the calculated regulation capacity of all uncertainty scenarios. Based on the constructed regulation capacity sample set, a multi-confidence level regulation curve library is constructed. The multi-confidence level regulation curve library is embedded as a constraint condition in the intraday rolling scheduling, and the power supply reliability criterion is set to calculate the power supply reliability, and the probabilistic evaluation result of the power supply reliability is obtained. It can adapt to the access demand of different types and different sizes of distributed energy resources.

Programming techniques disclosed herein may be used to recover from potential plane and / or die level failures. The memory system may detect evidence of a plane or die level failure that impacts memory operations performed in a target region of the blocks if a first programming technique is used in the target region. For example, the memory system may note that a significant number of blocks have memory operation failures in the target region. The storage system switches to a second programming technique for programming the target region responsive to detecting evidence of a plane or die level failure. The blocks may be tested for a reliability criterion after programming using the second programming technique in the target region of the block. The second programming technique may overcome the plane or die level failure such that blocks may continue to be used with the second programming technique.
