英文摘要：

This paper proposed a stochastic model predictive control（SMPC） based energy local network（ELN） optimization and scheduling method for reducing the impacts introduced by the intermittent output of renewable energy resources, fluctuant of load demand and random real-time electricity price of a high renewable energy penetration level ELN. We constructed a mixed integer quadratic programming model as the objective function of the ELN operation by analyzing the features of all the elements in the ELN, and this optimization model can be online operated in a stochastic model predictive control（SMPC） framework. Forecast uncertainty for power production of renewable energy resources, real-time electricity price and load demand were described by scenarios, and a two-stage scenario cutting method was proposed to choose the typical scenarios. Simulation results show that the method proposed in this paper is effective and feasible by comparing with the open-looped operation method and MPC based operation method.
