N2 - Abstract: Nowadays, renewable energy sources (RES), especially solar and wind, slowly replaced non-renewable energy in power generation in a grid system because non-renewable energy results in an environmental issue like global warming. With the recent improvement and development, RES technology has slowly become a trend in power generation. Plus, the rotational generator system is gradually replaced by the inverter-dominated system due to the rise of RES. However, the replacement of RES results in a lack of inertia. Plus, the power generated by RES is unstable because it is highly dependent on weather. Thus, a synchronverter and energy storage system (ESS) with a bidirectional DC/DC converter (BDC) can be added to the grid system to provide virtual inertia to ensure the stability, reliability and power flow of the grid system. In this report, the charging and discharging properties of ESS in different modes controlled by the energy management system are discussed. Moreover, the frequency, active power (P), reactive power (Q) and output voltage, and current due to different load, are also discussed in this paper. Thus, the main objective of this report is to present the integration of solar power system, ESS and synchronverter in a power system. The integration of the system is simulated in MATLAB/Simulink, and the results are shown.
