| description | This paper presents the design of an adaptive active power controller to enhance the power-sharing capabilities
of distributed generators (DGs) in an autonomous microgrid. Each DG in an autonomous microgrid consists of a
droop-controlled inverter to control active and reactive power by regulating frequency and voltage correspondingly.
The high droop gain can be used in the power controller to encourage faster power sharing among the DGs. However,
high droop gain can cause undamped growing oscillations during load fluctuations or generation losses. During
such events, attaining faster power-sharing between DGs using high droop gains is difficult. So, the problem with an
autonomous microgrid is the conflict between faster power sharing and stability. Stability needs to be compromised to
attain quicker power sharing and vice versa. Hence, to achieve power-sharing swiftly with high droop gain and
to diminish the growing oscillations caused, this paper proposes a fuzzy logic-based adaptive active power
controller (FLAPC). The proposed FLAPC is adaptive and easy to implement. It offers faster power sharing for different values of droop gains and step change in load. The FLAPC is developed in MATLAB 2018a/Simulink environment, and time domain simulations are performed to see the efficacy of the proposed controller. The results of time domain simulations are compared with a droop controller without any additional controller, conventional lead-lag power system stabilizer, and proposed controller for step change in load at different droop gains. The results show that the proposed controller enhances the power-sharing performance and also ameliorates the system’s stability by reducing the settling time and overshoot in active power responses of DGs. |
