“…The three inverters have a phase difference of 120 °and the configuration of the inverters generates a three-phase voltage source (Manias, 2017). The power requirements of the microgrid system dictate the exchanges of power between the microgrid systems and the utility grid via a bidirectional inverter/rectifier (Debela, Ensermu and Bhattacharya, 2017). VSI generates an output waveform in which parameters such as frequency, voltage, and harmonic content are controlled (Narayanan, Seema and Singh, 2018).…”

“…There are three common control techniques for PWM inverters, and they include single PWM, Multiple PWM, and Sinusoidal Pulse Width Modulation (SPWM). A study conducted by (Debela, Ensermu and Bhattacharya, 2017) found that using an SPWM inverter produced a 300 V peak on the AC power supply, resulting in a 95% conversion efficiency under steady-state conditions. The most frequently used modulation is the SPWM because of its apparent usage in industrial applications (Kim, 2017).…”

Solar Photo Voltaic (PV) powered community microgrids are a promising sustainable solution for neighborhoods, residential quarters, and cities in sub-Saharan Africa (SSA) to meet their energy demands locally and to increase energy independence and resilience. This review provides a comprehensive study on the nature of solar PV community microgrids. Through their capacity to operate in both grid-connected and island modes, community microgrids improve utility system resiliency while also boosting energy security in local states and towns. The integration of solar PV microgrids with the electricity utility grid requires control strategies to facilitate the load sharing between distributed generation units, voltage and frequency control, as well as emergency islanding. Control strategies such as hierarchical control and droop are discussed in the review article. To identify the effectiveness of control strategies through system simulation, a review of various modeling designs of individual components in a solar PV microgrid system is discussed. The article goes on to talk about energy optimization approaches and their economic impact on microgrid systems. Finally, the review concludes with an overview of the technical challenges encountered in the integration of solar PV systems in microgrids.
