N2 - This paper introduces a new method for optimal planning of a hybrid AC/DC microgrid (HMG). The existing works have not addressed the simultaneous optimal sizing of battery energy storage systems (BESSs) and interlink converters (ILCs). In addition, the degradation cost of the ILC has not been considered in existing works focused on the planning of HMGs. In this paper, the energy throughput concept is adopted as a constraint to limit the number of charge and discharge cycles of the BESS, minimising the cyclic aging of the batteries. The Arrhenius equation, commonly used to model fatigue in semiconductor devices, is applied to model the degradation cost of the ILC. Real data from the Australian National Electricity Market and Griffith University is used to model a real-life HMG, and several scenarios are modelled to signify the expandability and feasibility of the proposed planning method in real systems.
