Appendix I: Brief Introduction about the
system operation modes:
Self-consumption Mode
The power generated by the energy storage system will mainly be
used to support the load, and surplus power will be adopted for
battery charging and once the battery is full, the more surplus energy
will be fed into the grid. It can effectively improve PV generation self-
use rate.
Users can not only save their electricity bill but also can get more
money by selling power to the grid.
Time-of-use Mode
Time-of-use mode is set based on the time-of-use tariff system. In
the electricity market where the time-of-use electricity price is
implemented, users can choose to charge the energy storage system
when the electricity price is low and discharge when the electricity
price is high, which can not only reduce the overall electricity
consumption cost through low storage and high discharge, but also
