Potential for New Energy Management by Variable Distribution Voltage Based on Electricity Consumption within Consumers

An energy management systems (EMS) such as building energy management systems (BEMS) and home energy management systems (HEMS) are widely used to reduce energy resources. This paper proposes an EMS that regulates the distribution voltage for energy efficiency within the consumer. The concept of the proposed EMS is as follows: the power distribution system regulates a distribution voltage to minimize the total loss by considering the operating conditions of various electrical devices installed in the customer's building. The effectiveness of the proposed method is validated by simulations and experiments using a prototype model.
