- Conclusions - 22 An exhaustive analysis is expected to assess the drawbacks and advantages of this topology modification; A simulation of the overall system is made to define the power/energy requirements; Control and energy approaches for the studied prototype are proposed using the EMR approach; Specific characteristics of recreational products were addressed; Two connected intervention area could be evaluated using the same EMR model and control structure: 1) H-ESS design; 2) Energy strategy; Usability of more accurate models to answer others objectives; Future works will be based on reduced-scale prototype in a laboratory and after on real-scale prototype implementation.
