Optimal Seasonal Wind Curtailment for Islanded Provisional Microgrid Operation

Abstract

Unlike traditional Microgrids, Provisional Microgrid (PMG) utilizes only renewable generation and small energy storage; thus, it does not have self-islanding capability and instead relies on importing power from a coupled microgrid (CMG) for islanding purposes. This paper proposes a scheduling optimization model to determine optimal scheduling of wind power curtailment for islanded provisional microgrid with an objective to minimize operation cost and ensure generation-demand balance. The impact of the seasonal net load variability on the model performance has been investigated in this work. The scheduling problem is formulated as a Mixed Integer Linear Programming (MILP) problem and solved using CPLEX tool. Numerical results demonstrate the effectiveness of the proposed model.
