Abstract

When considering issues such as power shortage, environmental pollution, and dependence on petroleum, a battery energy storage system (ESS) is one of the promising options to overcome these problems. This paper deals with a 3 kW residential battery ESS that consists of a buck/boost power conversion unit, a DC/AC bidirectional conversion unit, and a Li-ion battery pack with a battery management system. In order to connect an ESS to the grid, the system needs to meet requirements such as having a bidirectional power flow, low THD, and anti-islanding. This paper presents an operation scheme and the implementation of a residential ESS. The scheme was experimentally verified on a prototype.
