Abstract: The optimisation, sizing and techno-economic assessment of stand-alone renewable energy systems affects not only the likelihood of deployment but also their reliability to supply electricity and potable water where needed. Very little work has been done earlier into the effects of integrating water desalination alongside meeting load demand. Moreover, the impact of intelligent techniques, in this context, against more established software tools has not been applied. In this paper, PSO (Particle Swarm Optimisation) is compared to HOMER for the simultaneous optimisation of size and PMS (Power Management Strategy) in stand-alone hybrid energy systems. These systems incorporate significant relative water load met by reverse osmosis. Multi-objective functions in PSO minimise Total NPC (Net Present Cost) (includes capital, maintenance and replacement costs over a 25 year system lifetime) and lifetime CO2 emissions whilst meeting these two loads. Results are analysed and compared for the conditions of dynamic (15 min resolved) versus static water demand in addition to meeting varying electric loads. The PSO algorithm is implemented using MATLAB/Simulink and compared to a similar overall configuration developed in HOMER to meet the same loads (electric, water).
