Microgrids – Voltage and Frequency Regulation
A Microgrid has a 3-tier hierarchical control structure. The voltage and frequency regulation is managed by both primary and secondary controls. Primary control adjust the fequency
A dynamic model of the DC-microgrid system described by a multi-input and multi-output nonlinear system with non-affine inputs is derived. This paper studies voltage regulation and maximum power point tracking (MPPT) control for a DC-microgrid that includes a photovoltaic (PV) panel, battery, constant resistance and constant power loads.
The control system should be able to regulate the voltage as well as the frequency, both during islanded operations of the microgrid and grid-tied operation. This paper gives an outline of a microgrid, its general architecture and also gives an overview of the three-level hierarchical control system of a microgrid.
The literature review summarizes the microgrid control methods to be employed in primary control. The majority of research is focused on the main control, particularly the traditional droop control approach and its improvements. Droop controllers maintain voltage and frequency fluctuations in position.
In microgrids, an effective control mechanism must be implemented to facilitate equitable distribution of load among multiple power sources, enhance power quality, and control DC bus voltage. The strategy of hierarchical control is best suited to address the aforementioned challenges, as it allows some autonomy between control levels .
