Operational Management of the Microgrid System for the Energy-sensitive Manufacturing Plant

The penetration of renewable energy sources brings a new opportunity to tackle the environment problem due to the fossil fuels. This paper considers a multiunit system consisting of the production system, the external electric grid system, the microgrid system including renewable energy system and energy storage system. A multistage stochastic programming model is established to allocate the energy generated by the renewable energy system during a finite horizon considering the uncertainty of the microgrid system due to the varied weather. Since the model is computationally intractable, an algorithm combining the Fibonacci search and the estimation of the second-stage cost is proposed. The numerical results validate the effectiveness of the solution approach.
