The seminar will present an integrated view of optimized capacity design and operation, of islanded energy hubs. We consider energy hubs that incorporate emerging distributed energy resources as well as energy storage devices, and fully support the electricity and heat demand of an islanded installation. To explicitly account for the stochasticity in renewable generation and load, the energy hub capacity design problem is first expressed as a chance-constrained optimization problem, and then reformulated as a robust counterpart problem. Battery charging/discharging responds to stochastic renewable generation and load realizations through a control policy. The design result demonstrates a balanced trade-off, between robustness and cost efficiency. After the energy hub has been designed, we propose a bi-level operating strategy, where a day-ahead schedule is optimized at the upper level. Model predictive control is used for tracking the schedule in real-time at the lower level. Finally, we discuss the potential for increasing the reliability of energy hub systems, while decreasing operational cost by sharing energy between multiple energy hubs through networking.
