Abstract

To meet the ever-increasing energy demand, microgrids connected to distributed energy-based grids will soon become the most reliable way to upgrade the electricity system. The introduction of microgrid systems brings great benefits to electricity providers and end users. Microgrid is usually connected to the main grid, that is, it operates in grid-connected mode and if the main grid does not provide electricity to users, the microgrid operates in island mode and provides independent power from the main grid. This paper presents a control strategy for a 7.5 KW hybrid microgrid with 1.5 kW wind and 6 kW solar installed at Maharashtra State College of Engineering. PQ control strategies and control strategies related to microgrid operation methods are focussed. This paper also discusses microgrids issues such as islanding mode, stability and voltage imbalance to ensure effective power quality. The P-Q control strategy, which balances real and reactive power with voltage control and current control, is a promising strategy for real power control in power systems without internal communication. A microgrid can provide stable and efficient performance by providing voltage and frequency support, improving power quality. Following this strategy, the PQ control simulation is completed and the promising results are obtained for the 415V and 18A system. Mathematical modeling of P-Q control and droop control is also established and compared with the simulation results. The comparative validation is also found to be successful.
