Abstract
A smart house generally has a Photovoltaic panel (PV), a Heat Pump (HP), a Solar Collector (SC) and a fixed battery. Since the fixed battery can buy and store inexpensive electricity during the night, the electricity bill can be reduced. However, a large capacity fixed battery is very expensive. Therefore, there is a need to determine the economic capacity of fixed battery. Furthermore, surplus electric power can be sold using a buyback program. By this program, PV can be effectively utilized and contribute to the reduction of the electricity bill. With this in mind, this research proposes a multi-objective optimization, the purpose of which is electric demand control and reduction of the electricity bill in the smart house. In this optimal problem, the Pareto optimal solutions are searched depending on the fixed battery capacity. Additionally, it is shown that consumers can choose what suits them by comparing the Pareto optimal solutions.
Highlights
Power systems reform has been performed in Japan
If the hot water temperature is less than 50 ◦C and 60 ◦C at 7 a.m. and 8 p.m., the hot water is heated by Heat Pump (HP)
Consumers in the smart house plan the usage of the appliances depending on the Real-Time Pricing (RTP) price
Summary
Power systems reform has been performed in Japan. In 2015, the Organization for Cross-regional Coordination of Transmission Operators (OCCTO) was established for the purpose of supply and demand adjustment of the national power transmission and distribution equipment, and in April 2016, full liberalization of retail electric power had started [1]. Smart meters, which can be checked remotely, will be installed, so in the future, it will be expected to construct a smart grid that can have a two-way communication with electric power demand in real time [3,4]. Full liberalization of retail electric power has been performed in Illinois, USA, and there is an electric power retail company that provides RTP price for general consumers [6]. This company notifies consumers having a smart meter of the day RTP price on the previous day. A consumer can reduce the electricity bill by modifying the time of electric appliance usage depending on the notified RTP price [7,8]
