A Simulink solar micro-grid model is developed in MATLAB Simulink and it is linked with JADE using MACSimJX for realizing the practical implementation of MAS in dynamic energy management and demand side management of solar micro-grid. to achieve the lowest possible cost under intermittent nature of solar power and randomness …
Read More »Fault Tolerance Considerations for Long Endurance AUVs
As the use of Commercial-Off-the-Shelf components is often a project objective including obsolescence management. there is an added requirement for DNCS to institute regular software and hardware updates. referred to as technology refresh. and is dictated by the relatively short supportability lifespan of commercial components. To allow for future technology …
