Decentralized Model Predictive Control of DC Microgrids With Constant Power Load

This article introduces a decentralized model predictive controller (DMPC) to ensure power sharing and regulate dc bus voltage in microgrids (MGs) with constant load (CPL). The proposed method replaces the conventional primary layer of MGs, i.e., inner loops droop control, single optimal controller. A automatic system is realized for prediction purposes be used cost function. control objectives are then incorporated function attain an state switching each sampling time, hence regulating accurate current among MG. solution provides fast dynamic response zero steady-state error. effectiveness verified by hardware-in-the-loop (HIL) real-time experiments, results compared control.
