基于半同态加密体制的安全分布式经济调度
Secure distributed economic dispatch based on semi-homomorphic encryption
摘要
Abstract
Economic dispatch(ED)is a basic and important problem in power system operation,which mainly involves how to accurately allocate and manage power generation resources to meet the load demand,while reducing the overall cost of power generation as much as possible.This paper proposes an economic dispatch algorithm based on distributed optimization from the point of view of the consensus protocol to minimize the generation cost of the power system.At the same time,a privacy-preserving scheme is developed based on the Paillier cryptosystem with semi-homomorphic en-cryption.This scheme can not only ensure that the information transmitted by the network is not obtained by malicious attackers,but also that the privacy information of each node is not obtained by other nodes.The Lyapunov energy func-tional is constructed to analyze the effect of the time-varying delay induced by encryption and decryption on the economic dispatch model,and the convergence condition that makes a tradeoff between conservatism and complexity is derived.The effectiveness and superiority of the method are illustrated by the simulation comparison.关键词
