Abstract: The integration of battery energy storage systems (BESS) with renewable energy is a
potential solution to address the disadvantages of renewable energy systems—charge and discharge,
and irregular and intermittent power. In particular, residential BESS is advancing in numerous
countries. Residential BESS integrated with PV can reduce energy consumption and costs. However,
Korea does not yet have a residential BESS market because of the high price of residential BESS, low
electric rate, progressive rate system, and limited PV capacity. Most residential houses in Korea are
apartment houses, and thus residential BESS can be used with veranda PV. This paper presents
optimal operation schemes of residential BESS with veranda PV for apartment houses in Korea. The
BESS capacity was estimated by considering the veranda PV capacity that can be installed in
households and power consumption. The applicability of the residential BESS was analyzed through
performance and economics evaluation under current and various conditions. Several operation
schemes were tested in a demonstration house, and preferential charging of the battery with PV power
and then with PV and grid power was found to be the most optimal. The results will contribute to
effective application of residential BESS with veranda PV in the near future.
