Dynamic Output-Feedback Decentralized Control Synthesis for Integration of Distributed Energy Resources in AC Microgrids

This work proposes a control design procedure based on Linear Matrix Inequalities (LMI) for integrating Distributed Energy Resources (DERs) in microgrid systems. Each DER uses local measurements as feedback, so this proposal results method to decentralized primary control. The dynamic model employed synthesize such controller presents an unmeasured state vector, uncertainties, and random disturbances. To simultaneously deal with all these difficulties while ensuring the closed-loop stability multiple performance specifications, is formulated terms of single Lyapunov function. find function gains, convex optimization problem that involves LMIs required be solved. linear discrete-time output-feedback form, facilitating its implementation. time-domain simulation system performed software PSCAD/EMTDC four DERs validate procedure’s effectiveness.
