Power system reactive power optimization method based on depth determination strategy gradient reinforcement learning
ActiveCN110535146AAchieve information exchangeImprove power utilizationReactive power adjustment/elimination/compensationReactive power compensationTerminal voltageTransformer
The invention provides a power system reactive power optimization method based on depth determination strategy gradient reinforcement learning. A deterministic depth gradient strategy algorithm is applied to the traditional power system reactive power optimization problem. The voltage state of the power system is sensed through a depth neural network, a corresponding action decision is then made by using a reinforcement learning method, a correct generator terminal voltage adjustment action, a node capacitor bank switching action and a transformer tapping point adjustment action are made to adjust reactive power distribution in the power system, the active power network loss of the power system is minimized. As the neural network is divided into an online network and a target network, association between parameter updating and adjacent training in each training process of the neural network is avoided, and the problem that reactive power optimization of the power system is caught in local optimization is avoided. On the premise of conforming to the security constraint of the power system, the economical efficiency of the operation of the power system is improved by reducing the network loss of the power system.

Content centric network privacy protection method based on hybrid encryption and anonymous group
The embodiment of the invention provides a content centric network privacy protection method based on hybrid encryption and an anonymous group. An interest packet is transmitted through the anonymous group, and decrypted into a plaintext interest packet layer by layer in a node of the anonymous group, thereby effectively preventing an attacker from getting association between the interest packet and a user. Hybrid encryption is performed on the interest packet and a data packet through encryption methods such as a user ID, a public key and a private key of a publisher, a symmetric key, and a public key and a private key of the anonymous group, so that the data packet can be protected from being modified in a process from signature to reception by the user, and plaintext content cannot be cracked inversely within certain time even though the attacker gets encrypted communication content by eavesdropping, thereby protecting the privacy of communication data. In the embodiment of the invention, the identity privacy information of a signer is protected through construction of the anonymous group, and meanwhile unlinkability between communication content and both communication parties is realized through a hybrid encryption method.
