A household load priority scheduling model based on real-time electricity price

In this paper, we present a household load priority scheduling model based on real-time electricity price, the optimization objective is to satisfy user´s comfort demand and reduce the electricity cost. The constraints are electric power company´s response to electrical and the working time of household appliances that user expect. The model divides all appliances into three categories: important appliances which cannot be dispatched, non-interruptible appliances which can be dispatched and interruptible appliances which can be dispatched, and the third type can be subdivided into demandable appliances and rechargeable appliances. The proposed model not only takes various electrical models of appliances into account, also including user´s psychological satisfaction. Electricity bill and users´ satisfaction curve will generated by the system, through adjusting the proportion of satisfaction, different users can get different power saving and comfort effect according to their different demands, it has important practical significance. Finally, the article verify the effectiveness of the proposed optimization model by simulations.
