Optimal Dispatch of Multi-Energy Integrated Micro-Energy Grid: A Model Predictive Control Method

In order to reduce the impacts caused by large-scale renewable energy resources accessing utility grid, micro-energy grid system, as a natural extension of microgrid in internet era, is proposed and developed provide new solution for optimal utilization resources. this paper, multi-energy integrated system which contains wind, PV, bedrock storage, magnetic levitation electric refrigeration, solid oxide fuel cell, solar thermal collector, V2G technologies, detailed models generation/conversion/storage devices are formulated. Besides this, uncertainties cold/heat/electricity loads considered, dispatch problem established from day-ahead real-time time scales based on model predictive control method. The scheduling aims at economic optimization guides scheduling, utilizes rolling feedback correction mechanism effectively correct deviation generations horizon, improves accuracy, follows plan, ensures economics same time.
