Abstract

Abstract: This paper proposes a comprehensive optimization scheduling strategy for unbalanced microgrid with three-phase imbalance including multiple distributed generations. Firstly, we determine the evaluation indices for the security, economy and efficient operation of three-phase unbalanced microgrid; establish the multi-objective optimization scheduling model; and obtain the running strategy of microgrid through solving the model. Secondly, we analyze each objective function from different operation angles, which can make full use of the effectiveness of the multi-objective approach. The example simulation verifies the effectiveness of the proposed optimization scheduling strategy in giving full play to all kinds of distributed generations.

Key words: unbalanced microgrid, distributed generation, energy storage, scheduling strategy, multi-objective optimization
