MicroGrid (MG) is a local distribution system where
loads are supplied by parallel-connected inverters controlled by
decentralized active power/voltage frequency and reactive
power/voltage magnitude droop controller. A paralleled ac
system, such as a multi-inverter MG with droop controller, is
susceptible to large variations in frequency/voltage magnitude.
Therefore, the protection issues are very important in these
systems. In this paper, a new controller is proposed to decrease
the frequency drop during transient time after events such as
load switching. Moreover, the proposed controller eliminates the
frequency deviation in steady state. Analysis of simulation results
validates that the proposed controller responses as reported in
the paper.
