Abstract :
This paper describes a new method for optimising the operation of stand-alone hybrid power systems containing some combination of auxiliary generator, PV generation and storage battery. The method provides a fast and accurate solution to the optimisation problem relative to previous methods. The method has been implemented on computer and an example control policy produced by the new method is presented and discussed. A comparison has been made between the new method and a conventional control algorithm under a simulation environment and using a deterministic future. This comparison has identified potential to reduce system operating costs
