1. Introduction
Recently, due to the governmentʹs energy 3020 policy, interest in energy saving is increasing and
the zero energy building business through ESS is being actively promoted. However, fire accidents
continue to occur with installations of ESS. In particular, because ESS facilities are installed in the field,
it is difficult to analyze the causes of accidents due to an absence of data.
In addition, due to situations in which there is no way for an administrator existing outside to
respond to a fire or error, a system through which an administrator can effectively respond to events is
required [1‐4].
In this environment, we propose the development of a standalone PMS and a remote control and
monitoring EMS for ESS safety operation. Applying standalone PMS to an existing ESS facility through
the proposed system and building an external WAS and data storage to operate an EMS that can be
remotely controlled and monitored. This makes it possible to solve the overall problems of ESS
operation such as securing safety of ESS operation installed in buildings and improving communication
and technical reliability of existing ESS [5‐7].
2. Materials and Methods
In Korea, under the supervision of KEPCO, prototypes are produced and various models are tested
in various areas with the participation of existing lithium battery manufacturers such as Samsung SDI
and LG Chemicals [8].
However, it is unlikely that the technology gap with foreign countries will be narrowed in a short
time, since domestic technology development has progressed slowly due to the lack of test evaluation,
safety certification, and incentives to install infrastructure and ESS. Overseas companies have advanced
technology because they have been successfully proceeding with commercialization, having focused
on development and experiments [9‐10].

3.1. PMS Design and Development
PMS consists of a Python‐based Postgresql database. The communication driver is supported by
RS232/485 to connect to a solar inverter and TCP / IP driver to support Modbus communication by
connecting to an internal network. System supports various OS such as Windows and Linux. The
developed PMS is designed to collect and control the data of ESS element facilities communicating
based on manufactured communication library modules for each facility.
