Abstract Increasing the efficiency of renewable energy usage is a newly-supplemented target for active distribution network (ADN) operation. Thereby, a multi-objective optimization framework for ADN operation that considers cross-regional utilization of renewable energy is proposed in this study. Firstly, based on the DC/AC model, the active/reactive decouple model of DG units under the centralized control mode is derived, and then the strategy for ADN operation considering cross-regional usage of renewable energy is put forward. Accordingly, a multi-objective model for ADN scheduling is built, taking the minimization of operation cost, renewable energy curtailment and network losses as objectives. In this model, the management for the active/reactive power output from DG units, energy storages and interruptible loads has been considered, taken the inter-temporal constraints into account. Due to high dimension and nonlinearity of the proposed model, the multi-objective harmony search algorithm is adopted. A modified 33-bus distribution system has verified the proposed method as well as the necessity for incorporating reactive capability of renewable-based DG units.
