Power grid systems have witnessed different kind of non-physical attacks being initiated from both internal and external sources that have resulted into physical damages and economical losses. The integration of computation and communication components within the power grid systems has resulted in enhancing the capability and improving performance efficiency of these systems. However, the incorporation of computation and communication modules open the doors for vulnerabilities that can lead towards cyber-attacks. The employment of effective cyber-security measures, playing the role of defense mechanisms in modern power grid systems, are of primary importance for both academia and industry led by governments initiatives. The development of cyber-security solutions for power grid systems requires profound knowledge of the physical components within the power system. This work proposed the design and development of a prototype for cyber physical energy systems that can be utilized as an experimental test bed suitable for executing a range of experiments concerning the performance impact of cyber-attacks on power grid systems and the effectiveness of countermeasure.
