Abstract
A Time-of-Use (TOU)-tariff scheme, helps residential customers to adjust their energy consumption voluntarily and reduce energy cost. The TOU tariff provides flexibility in demand, alleviate volatility caused by an increase in renewable energy in the power system. However, the uncertainty in the customer’s behavior, causes difficulty in predicting changes in residential demand patterns through the TOU tariff. In this study, the dissatisfaction model for each time slot is set as the energy consumption data of the customer. Based on the actual customer’s consumption pattern, the user sets up a model of dissatisfaction that enables aggressive energy cost reduction. In the proposed Home Energy Management System (HEMS) model, the efficient use of jointly invested offsite photovoltaic (PV) power generation is also considered. The optimal HEMS scheduling result considering the dissatisfaction, cost, and PV curtailment was obtained. The findings of this study indicate, that incentives are required above a certain EV battery capacity to induce EV charging for minimizing PV curtailment.
Highlights
A Home Energy Management System (HEMS) is a home automation solution based on the Internet of Things (IoT)
The IoT is versatile in terms of connectivity, as it connects a network of computers and other devices such as home appliances and networks resulting in interoperability [1,2]
The importance of HEMS is increasing because it helps residential customers to optimize energy consumption by improving energy efficiency through smart home appliances
Summary
A Home Energy Management System (HEMS) is a home automation solution based on the Internet of Things (IoT). Home automation has benefitted with the application of Artificial Intelligence (AI) technology. When the system detects the resident’s arrival within a certain distance of the home, the air conditioner in the house can changes from the energy-saving mode to the customer’s preferred temperature, lights can go on as the resident enters the house, and music can be played [3]. With the development of IoT and AI technologies, smart home appliances such as air conditioners, washing machines, and dishwashers that combine IoT with AI technology have the ability to provide advanced services to residential customers [4]. The importance of HEMS is increasing because it helps residential customers to optimize energy consumption by improving energy efficiency through smart home appliances
