The application relates to an energy coordination control method, device, equipment and medium for a hybrid energy storage system. The method comprises the following steps: acquiring total power instruction data of the hybrid energy storage system, state of charge parameters of energy storage units of the hybrid energy storage system, and real-time delay observation data between the energy storage units; selecting other energy storage units as neighborhood energy storage units of the energy storage unit; obtaining a neighborhood charge state prediction value set of the energy storage unit based on the state of charge parameters, the real-time delay observation data and a preset state prediction model; quantifying delay effects of each neighborhood energy storage unit of the energy storage unit based on the real-time delay observation data to obtain a delay adaptive weight set; and distributing the total power instruction data to each energy storage unit based on the state of charge parameters, a preset rated power capacity set, the neighborhood charge state prediction value set and the delay adaptive weight set to obtain power control instructions of each energy storage unit. The method can improve the timeliness and accuracy of energy control.

The invention discloses a power grid database security protection method and device, equipment and a medium, and relates to the technical field of data security access, the method comprises the following steps: identifying a plurality of groups of historical access logs of a power grid database to obtain a plurality of historical access behaviors, and analyzing and extracting to obtain corresponding access behavior characteristics; performing density-based clustering analysis on all the access behavior characteristics to obtain a plurality of behavior modes; predicting a risk coefficient of each behavior pattern based on a long short-term memory network model, and classifying the plurality of behavior patterns into a plurality of risk levels; matching a first behavior mode corresponding to the plurality of behavior modes according to the current access behavior, determining a protection strategy according to a first risk level determined by the first behavior mode in combination with the behavior intention of the current access behavior, and performing security protection; wherein the behavior intention is obtained based on analysis of the current access behavior. According to the method, the access behavior can be accurately identified, so that the power grid database is reasonably and safely protected.

The invention discloses a resource pool allocation method and device, and the method comprises the steps: carrying out the analysis of a resource allocation request when the resource allocation request is received, and obtaining an operation system, a system level, at least one node type, and the number of devices corresponding to each node type; screening a model list corresponding to the operating system from a database resource pool; screening out a CDP corresponding to the type list, the node type and the system level from all CDPs in the database resource pool, and identifying the CDP as a target CDP; if the number of devices in the target CDP meets the number of devices corresponding to each node type, setting the priority of each type; and distributing equipment in the target CDP according to the priority and the node type of each type. The resource allocation request is split into a plurality of conditions, and the CDP is matched according to the conditions, so that the change of the resource pool can be flexibly coped with. When the equipment changes, the allocation strategy can be quickly adjusted, and accurate allocation of resources is ensured, so that the allocation accuracy is improved.
