Performance of power electronic interfaced DERs integrated with communication network

In this paper, the performance of power electronic interfaced distributed energy resources (DERs) operating with communication network is investigated. The application of power electronic interface is required, for system operation and control while achieving a stable system with high power quality. In a smart grid scenario, due to the dependency of data acquisition, protection and control, an integrated communication is essential, to improve the system reliability and efficiency. The integrated communication will create a dynamic and real time information exchange. This information are used to operate many intelligent electronic interfaces. The reference signals of the power electronic devices are largely based on those communicated measurements and information. Depending on the communication technology, these measurements can vary in quality, update rate, sensitivity and noise. This paper investigates the performance of the distributed resources operating with power electronic interfaces and communicated measurements. Close loop simulation of the power network and communication network is carried out with SIMPOWER and TRUETIME respectively.
