Abstract
This paper introduces an innovative approach to residential energy management by integrating load shifting options and battery storage systems. It is considered a linear model along with various levels of user discomfort associated with shifts in appliance schedules. The study examines how optimized load shifting can synchronize energy-intensive activities with periods of low demand, resulting in reduced costs and user discomfort. The objective function minimizes the weighted sum of energy costs and discomfort calculations derived from appliance shifts. Different weighting factors in the objective function yield varying levels of inconvenience for end-users, allowing them to tailor the approach to their preferences. This comprehensive strategy offers valuable insights into optimizing residential energy management while addressing user comfort concerns. Additionally, the case study contributes a dataset of shiftable home appliances, serving as a valuable resource for evaluating the effectiveness of novel approaches to this problem. • Novel linear mechanism for calculating discomfort associated with shiftable appliances. • Mixed Integer Linear Programming formulation aimed at minimizing inconvenience to household users by considering both energy costs and discomfort. • Evaluation of the impact of energy storage systems in combination with load shift options on the energy management system problem.
