Abstract

This paper investigates a distributed energy management strategy for the port power system under false data injection attacks. The attacker can tamper with the interaction information of energy equipment, penetrate the boundary between port information system and port power system, and cause serious operation failure of port energy equipment. Firstly, a hierarchical topology is proposed to allocate the security resources of the port power system. Secondly, by reconstructing the topological structure of the port information system, the robustness of the information system is improved, and the impact of false data injection attacks on the port power system is reduced, which realizes secure distributed energy management of the port power system. Finally, the simulation results show the effectiveness of the proposed strategy, and the defense capability of the port power system is improved.

Highlights

With the development of the shipping industry [1], the types and quantities of energy equipment in port are increasing, and the port has become an energy-intensive region that relies on fossil energy; pollutant emissions are increasing year by year [2]
(2) To increase the security capacity of the port power system under false data injection attacks, this paper proposes a hierarchical topology reconstruction method of the port information system, which can reduce the impact of false data injection attacks on the port power system during the whole operation condition
Ere are a total of eight nodes in the network of the information energy system: 􏼈v1, v2, v3􏼉 are protected nodes, 􏼈v4, v5􏼉 are ordinary nodes, and 􏼈v6, v7, v8􏼉 are the nodes that are attacked. e network after topology reconstruction is shown in Figure 5, which divided nodes into two layers: the protected nodes are in the first layer and the other nodes are in the second layer. e information transfer from the first layer to the second layer in the topology is directed

Summary

Introduction

With the development of the shipping industry [1], the types and quantities of energy equipment in port are increasing, and the port has become an energy-intensive region that relies on fossil energy; pollutant emissions are increasing year by year [2]. The energy management of port mainly draws on the experience and methods of the distribution grid, and it is an optimization problem of the complex system considering various practical constraints [10] It aims to realize the balance of supply and demand and to maximize the operation benefit of the port power system when meeting the physical constraints of energy equipment [11, 12]. Is paper proposes a distributed energy management strategy for the port power system based on hierarchical topology reconstruction of communication networks in order to reduce the impact of false data injection attacks on port energy management within limited defense resources to ensure the safe run of the system with lower security defense cost.
