A smart grid is a new form of electricity network with high fidelity power-flow control, self-healing, and energy reliability and energy security using digital communications and control technology. To upgrade an existing power grid into a smart grid, it requires significant dependence on intelligent and secure communication infrastructures. It requires security frame-works for distributed communications, pervasive computing and sensing technologies in smart grid. However, as many of the communication technologies currently recommended to use by a smart grid is vulnerable in cyber security, it could lead to unreliable system operations, causing unnecessary expenditure, even consequential disaster to both utilities and consumers. In this paper, we summarize the cyber security requirements and the possible vulnerabilities in smart grid communications and survey the current solutions on cyber security for smart grid communications.

This work presents a novel control approach for AC Hubs, interconnecting offshore wind farms and different mainland grids via HVDC links. There are several proposals for a European overlay grid by different associations. This is where AC Hubs come into play. In order to implement such a grid in the North Sea, wind farms and long distance HVDC transmission lines need to be interconnected. The two options considered for interconnection are multiterminal HVDC configurations or AC Hubs. This work concerns itself with a novel approach for the control of AC Hubs. A technical model based on common control strategies is established and verified by simulation in MATLAB/Simulink. The main objective is to guarantee flawless operation of the AC Hub in absence of fast and reliable communication. This is achieved by applying a droop control scheme, which is similar to control strategies that are typically applied to microgrids or synchronous generators in the conventional electrical grid. After introducing the control strategy, a system layout is chosen, which is loosely based on existing data of offshore wind farms and literature discussing the future scenario of an HVDC
