Cyber Security in Future Power Systems


Project Description

With the increase interest in renewable power generation, the demand for a smart and
intelligent power system is increasing. This has led to the use of digital communication
infrastructure in power systems called smart grid. Smart grid offers many advantages such as
the availability of uninterrupted power supply to consumers, reduction in line losses,
accommodating increase renewable generation and storage, involvement of consumers in
electricity markets, and demand side response. Future power systems or smart grids will have
increase share of renewable generation such as solar and wind as well as rely on storage.
These renewable generation and storage rely on power electronic converters. Each
manufacturer of converters/inverters use their own algorithm to programme their hardware
and make it efficient. Additionally, these converters rely on communication protocols to
respond to any signal from system operator. Therefore, these smart converters/inverters are
vulnerable to cyber-attacks. Although various Cyber Physical Systems (CPS) have been
proposed in the past, there is no universal standard for CPS which can be used with different
types of converters. This project is aimed to investigate the various cyber challenges for
power system operator incorporating increase converter connected generation into the
system. The specific objectives of the project are outlined below.
Objectives:
1. Investigate the various challenges arises with the use of smart converters
2. Investigate the existing CPS, their advantages, disadvantages and limitations
3. Develop CPS for future power systems
4. Incorporate the knowledge in future standards for CPS in power systems

Important note: The candidate will be based at Edinburgh Napier University, UK and the candidate will be supervised by a team of experts including: Dr Jawad Ahmad, Dr Arshad (Research fellow at University of Strathclyde), Prof Bill Buchanan.
