Abstract
In islanded AC microgrids consisting of renewable
energy sources (RES), battery-based energy storage system
(BESS), and loads, the BESS balances the difference between the
RES power and loads by delivering/absorbing that difference.
However, the state of charge (SOC) and charging/discharging
power of the battery should be kept ...
In islanded AC microgrids consisting of renewable
energy sources (RES), battery-based energy storage system
(BESS), and loads, the BESS balances the difference between the
RES power and loads by delivering/absorbing that difference.
However, the state of charge (SOC) and charging/discharging
power of the battery should be kept within their design limits
regardless of variations in the load demand or the intermittent
power of the RES. In this paper, a supervisory controller based
on fuzzy logic is proposed to assure that the battery power and
energy do not exceed their design limits and maintaining a stable
power flow. The microgrid considered in this paper consists of a
PV, battery, load and auxiliary supplementary unit. The fuzzy
logic controller alters the AC bus frequency, which is used by the
local controllers of the parallel units to curtail the power
generated by the PV or to supplement the power from the
auxiliary unit. The proposed FLC performance is verified by
simulation and experimental results.
