In this work, relevant literature with regards to sizing and designing renewable energy systems microgrid have been analysed and discussed. These sizing methods were found to have been categorised mainly as intuitive, numerical, artificial intelligence, and hybrid methods. However, from preliminary investigation performed via simulation in MATLAB, using three simple numerical sizing methods from existing literature, justified the validity for the inclusion of an active energy management strategy to enhance the reliability of hybrid energy storage systems while limiting the use of non-renewable sources. In conclusion, the sizing of hybrid energy storage systems’ assets alone was shown to be inadequate to cater for uncertainty and intermittent renewable energy sources, an underpinning element in the design of reliable microgrid
