Smart grid coordination in building HVAC systems: Computational efficiency of constrained economic linear optimal control
In the context of day-ahead or real-time electricity prices, the method of economic model predictive control has been shown to provide expenditure reduction in building HVAC systems, specifically if coupled with active thermal energy storage. However, due to the diurnal nature of electricity prices, these expenditure reductions can only be achieved if the economic model predictive control prediction horizon is sufficiently large, typically greater than 12 h. This work develops an alternative controller known as constrained economic linear optimal control. This constrained economic linear optimal control policy is shown to yield economic performance similar to a large-horizon economic model predictive control policy but also possesses a virtual insensitivity to horizon size. Thus, application of the constrained economic linear optimal control policy will require a fraction of the computational effort while yielding nearly identical economic performance.
