Modeling and Dynamic Behavior
of Battery Energy Storage
A simple model
for large-scale
time-domain
stability studies.
ITH THE CONTINued development
and proliferation of
renewable energy
systems worldwide,
particularly wind and photovoltaic
(PV) generation, computer simulation models for these technologies
to be used in large interconnected
power-system stability analyses
have been a key focus over the past
several years. Such computer simulation models are used by powersystem planners and operators to
simulate various scenarios of large
interconnected systems-e.g., continental Europe and the western or
eastern North American grid-to assess the stability and reliability of the bulk electric power system. In Europe, much of
this work has been led by efforts within the International
Electrotechnical Commission, while in North America,
most of the major efforts in modeling has gone through
the Renewable Energy Modeling Task Force (REMTF) of the
Western Electricity Coordinating Council (WECC). The total
nameplate capacity of wind generation installed worldwide has surpassed 360,000 MW, and PV generation has
surpassed 130,000 MW, with the top three countries in

terms of cumulative total capacity being China, the United
States, and Germany.
More recently, energy-storage systems, such as the battery system shown in Figure 1, are being considered and
deployed in many regions in North America. Energy storage comes in many forms and different technologies and
offers a means of storing energy that is often produced by
renewable energy systems, such as wind generation, during off-peak hours (e.g., at night) and reusing the energy
during peak demand. Also, energy-storage technologies
offer many other potential benefits such as helping to
reduce the variability of the power output of variable energy sources (wind and PV generation) as well as providing
voltage control and frequency regulation capabilities. For
