Cyber-Physical Dynamic Simulation of Large-scale Transmission and Distribution Networks for Secure Distributed Energy Resources Integration
Xin Fang | xfang@ece.msstate.edu
Abstract: Distributed energy resources (DERs) are being rapidly deployed in distribution networks, which brings new challenges and opportunities to balancing the power system and stabilizing the system frequency. For reliable power system operation, regulation services are used to stabilize the system frequency through automatically balancing the system generation and load. To better leverage the capability of DERs providing grid services, the cyber-physical dynamics of DERs should be modeled to consider DER communication variations. In addition, the dynamic behavior of a large number of DERs should be accurately captured. In this seminar, a Cyber-Physical Dynamic Simulation (CPDS) model to capture the uncertainty of the two-layer communication latency and power dynamics of DERs will be presented. The variability of the DER communication delays and dynamic constraints are comprehensively modeled in this work. The DER AGC model with communication delay is designed to validate DERs’ frequency regulation services. Like current performance-based frequency regulation evaluation, the delivery of the DER frequency regulation will be assessed through post-analysis of the actual AGC response with respect to the AGC control signal from system operators. Consequently, the reliability improvement with DERs providing reliable frequency regulation services can be evaluated from a comprehensive perspective considering all the dynamics of communications and power.
