Operation strategy of energy hub for commercial buildings based on tiered temperature control

In this study, the author considers an operation strategy of energy hubs for commercial buildings based on tiered temperature control, with the objective of balancing the operation cost and comfort level. A tiered temperature deviation penalty tariff is formulated to measure different levels of temperature deviation. Considering a set of uncertain factors, including photovoltaic output, load demand and outside temperature, this stochastic optimisation model can be converted into a mixed-integer linear program, solved by commercial optimisation solver, CPLEX. Numerical simulations verify the efficiency of the proposed operation strategy.
