Dynamic dispatch of isolated neighboring multi-microgrids based on model predictive control

摘要

This paper propose a mathematical formulation of energy management problem and its implementation in an energy management system (EMS) for isolated neighboring multi-microgrids. Using the model predictive control technique, the optimal operation of the microgrids is determined by utilizing an extended horizon of prediction and evaluation, which allows a proper scheduling of the energy storage units, responsive loads, and controllable distributed generators. A finite mixed integer quadratic programming problem is modeled and solved with both forecasts and newly updated system state information. Case study is employed to assess the performance of the proposed approach and simulation results show that the operation costs of coordinated multi-microgrids is lower than that of operated individually.
