Computationally efficient representation of energy grid-cyber physical system

The computation integrity of the cyber part of an Industrial Cyber Physical System requires a reliable executable model of the underneath physical system. This physical system is usually a continuous-time one and its model execution requires resources far beyond existing embedded computing capabilities. The need for capturing the real time transient behavior of a physical system imposes additional burden in CPS in terms of computational time steps. In this work, we present that it is feasible to emulate a physical system (the Distribution Energy Grid in this case) by direct mapping it on hardware computational resources while maintaining its real time transient behavior. The hardware mapped physical system model can then act as a co-processing element to the CPS computational part. The focus on the real time transient behavior of a modern distribution grid-CPS, is inevitable due to the extended use of power electronic devices, intermittent generation and fast switching smart metering devices.
