Peak demand control system using load prioritisation for domestic households

Vast peak demand management approaches are being implemented in the residential space, and some of them involve automated switching control strategies. Controlled switching of appliances during peak periods minimizes demand and energy consumption, however this may constrict the consumer's flexibility to utilize desired appliances to fulfil their needs. This article presents the experimental implementation of an end-use appliance control simulation study, for performance evaluation of a control technique. The system prototype was built based on an end-use appliance, switching control technique embedded with an event detector algorithm. The performance of the switching control device was evaluated in a lab-home-representative environment. Factors surrounding occupant's energy consumption behavior and issues on frequent switching of appliances are discussed. Validation of device performance was done through experimental tests and results obtained revealed that the control system is feasible as it contributed towards peak demand and energy consumption reduction. Results also show the effectiveness of the system in increasing user's preferred appliance (UPA) usage flexibility margin.
