Abstract
This paper discusses energy management and control algorithms of microgrid with energy storage. Specific management framework within microgrid
presented here includes: a) help prioritizing the renewable energy sources (RES) to provide power to local loads, b) manage battery to avoid deepdischarging and overcharging, c) maintain dc link voltage at a specified value, and d) regulate ac voltage buses at nominal voltage and frequency. The
system analyzed here is adopted from Consortium for Electric Reliability Technology Solutions (CERTS) microgrid test bed. While the generation
priority is from RES, the system also has a thermal generation unit to compensate for renewable energy variability and interm ittency. Depending on
battery state of charge (SOC) and power difference between photovoltaic (PV) and the load, the energy management can work with several modes:
charging, discharging, export power, import power, and halt. The system is simulated in PSCAD platform and shows that energy management and
control algorithms work as expected. © 2014 IEEE.
